Title: Work platform system including suspended paneled portion and method of implementing same

Description:
FIELD OF THE INVENTION 
     The present invention relates, generally, to the field of work platform systems that are erected to facilitate accessing various parts of various structures. More particularly, the present invention relates to work platform systems that are capable of being erected to extend lengthwise over significant distances between end regions, where the work platform systems further extend beneath at least some portions of the structures with respect to which the work platform systems are facilitating access. 
     BACKGROUND OF THE INVENTION 
     A number of types of work platform systems are available on the market for use in a variety of environments, circumstances, and projects including, for example, construction or maintenance projects. Whether a project is a public works project (e.g., low bid), or a private project, reducing costs and/or maintaining costs at reasonable levels are important considerations for the parties involved (e.g., contractors and/or the owner). One environment in which work platform systems are used is along and particularly beneath structures that extend significant distances lengthwise, such as bridges. Such work platform systems can be employed for various reasons including, for example, to allow workers to perform various maintenance procedures (such as inspecting, cleaning, painting, repairing, or refurbishing) or construction procedures with respect to the structures, particularly in relation to regions along or proximate underside regions of the structures such as along the undersides of bridges. Also, such work platform systems can serve to perform a shielding function in terms of limiting the extent to which debris arising from such maintenance or construction procedures or otherwise can fall to regions beneath the work platform systems. 
     Various conventional work platform systems exist that can be implemented in such environments, and these various work platform systems vary in a number of their attributes. At least some such conventional work platform systems are catenary-based systems in which deck portions are mounted on wires that extend between end regions of the overall work platform systems, where the wires are further suspended at various intervals along the lengths of the wires by way of additional supports. 
     Although some such catenary-based systems can be relatively inexpensive to implement, at least some of these systems can be disadvantageous in certain respects. Among other things, one or more conventional catenary-based systems can be relatively difficult to erect or require conditions (e.g., lane closure) or expertise for proper implementation that are difficult to obtain or guarantee. Also, one or more conventional catenary-based systems are made of components that are limited in terms of lifespan or reusability, and/or employ components that lack sufficient durability or stability or are ergonomically undesirable for other reasons. Further, at least some such conventional systems provide walking surfaces that lack desired levels of flatness (e.g., the walking surfaces bend or experience excessive undulation). 
     For at least these reasons, therefore, it would be advantageous if a new or improved work platform system and/or method of use (e.g., in terms of installing the work platform system) could be developed that addressed one or more of the above-described concerns, and/or other concerns. 
     SUMMARY OF THE INVENTION 
     In at least some exemplary embodiments, the present invention relates to a work platform system for implementation in relation to a structure. The work platform system includes a first flexible element and a second flexible element, where a respective first end of each of the flexible elements is coupled at least indirectly to a first support component and a respective second end of each of the flexible elements is coupled at least indirectly to a second support component. The work platform system also includes a plurality of panel structures supported upon the flexible elements and substantially extending between the first flexible element and the second flexible element, wherein the panel structures are positioned in succession with one another so as to form a row of the panel structures extending along the flexible elements. Each of the panel structures includes a first pair of opposed edges each extending substantially parallel to the flexible elements and a second pair of opposed edges each extending between the first pair of opposed edges. A first of the panel structures includes a first support extension extending outward away from a first one of the respective second pair of opposed edges of the first panel structure. Additionally, the first support extension of the first panel structure includes a first formation into which a second one of the respective second pair of opposed edges of a second of the panel structures is positioned, the first formation serving to at least partly limit movement of the second panel structure relative to the first panel structure. 
     Additionally, in at least some embodiments, the present invention relates to a work platform system for implementation in relation to a structure. The work platform system includes a first pair of flexible elements and a second pair of flexible elements, where a respective first end of each of the flexible elements is coupled at least indirectly to a first support component and a respective second end of each of the flexible elements is coupled at least indirectly to a second support component. The work platform system also includes a plurality of panel structures supported upon the flexible elements and substantially extending between the first pair of flexible elements and the second pair of flexible elements, where the panel structures are positioned in succession with one another so as to form a row of the panel structures extending along the flexible elements. Each of the panel structures includes a first pair of opposed edges each extending substantially parallel to the flexible elements and a second pair of opposed edges each extending between the first pair of opposed edges. A first of the panel structures includes a first support extension extending outward away from a first one of the respective second pair of opposed edges of the first panel structure. Additionally, the first support extension of the first panel structure includes a first formation into which a second one of the respective second pair of opposed edges of a second of the panel structures is positioned, the first formation serving to at least partly limit movement of the second panel structure relative to the first panel structure. 
     Additionally, in at least some embodiments, the present invention relates to a work platform system for implementation in relation to a structure. The work platform system includes a first pair of flexible elements, a second pair of flexible elements, and a third pair of flexible elements, where a respective first end of each of the flexible elements is coupled at least indirectly to a first support component and a respective second end of each of the flexible elements is coupled at least indirectly to a second support component. The work platform system further includes a plurality of panel structures supported upon the flexible elements. Each of the panel structures includes a first pair of opposed edges each extending substantially parallel to the flexible elements and a second pair of opposed edges extending between the first pair of opposed edges. A first of the panel structures is supported upon at least one flexible element of the first and second pairs of flexible elements, substantially extending between the first and second pairs of flexible elements. A second of the panel structures is supported upon at least one flexible element of the second and third pairs of flexible elements, substantially extending between the second and third pairs of flexible elements. At least a first portion of the remaining plurality of panel structures are positioned in succession with the first panel structure and at least a second portion of the remaining plurality of panel structures are positioned in succession with the second panel structure, thereby forming two rows of panel structures extending along the flexible elements. The work platform system further includes a plurality of additional cover portions positioned between the two rows of panel structures and at least indirectly engaging both flexible elements of the second pair of flexible elements. 
     Further, in at least some embodiments, the present invention relates to a method of implementing a work platform system in relation to a structure. The method includes attaching a first pair of flexible elements and a second pair of flexible elements at least indirectly to a first support and a second support, respectively, and installing a first panel section onto the first and second pairs of flexible elements. The method also includes installing a second panel section onto the first and second pairs of flexible elements, where the installing of the second panel section includes placement of a second side edge of the second panel section into at least one support component extending outward from a first side edge of the first panel section and rotating the second panel section until the second panel is supported on the first and second pairs of wire extensions.

     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , a side elevation view is provided of a suspension bridge  100  in combination with a partly implemented (or partly installed) work platform system  110  that is being implemented in relation to the suspension bridge for the purpose of allowing one or more work operations to be performed by work personnel in relation to the suspension bridge. It should be appreciated that the suspension bridge  100  is merely one example of a structure in relation to which a work platform system such as the partly implemented work platform system  110  (or that work platform system when in a different state of implementation as discussed further below) can be implemented and utilized. That said, the present disclosure is intended to encompass work platform systems and implementations of work platform systems in relation to any of a variety of structures rather than merely suspension bridges. Thus, although  FIG. 1  shows the suspension bridge  100 , it should be appreciated that the present disclosure is intended to encompass work platform systems and implementations of work platform systems in relation to a variety of other structures including, for example, other types of bridges such as arched bridges, buildings, towers, rigs (e.g., oil rigs), piers, conveyors, and other structures. 
     It is envisioned that at least some of the work platform systems disclosed herein are particularly suitable for use in relation to structures such as the suspension bridge  100 , where it is desired that the work platform system extend significant distances along (and often underneath) the structure. To this end, the present disclosure particularly encompasses work platform systems that include both a respective support subsystem and a respective suspended subsystem that extends (and potentially extends significant distances) between portions of the support subsystem. In this regard, referring still to  FIG. 1 , it can be seen that the partly implemented work platform system  110 , even when in the partly implemented state as shown, both includes a partly implemented suspended subsystem  120  as well as a support subsystem  130 . As shown, the support subsystem  130  includes a first portion  132  and a second portion  134  that respectively are at opposite ends of the partly implemented suspended subsystem  120  and respectively supported upon respective towers  140  of the suspension bridge  100 , with the partly suspended subsystem  120  extending between the portions  132  and  134  of the support subsystem  130 . 
     It should be appreciated that, although  FIG. 1  begins by showing the work platform system  110  in a partly implemented state, it will be apparent from additional description provided below as to how this work platform system (and particularly the suspended subsystem thereof) is further modified so as to include additional components and otherwise take on additional features so as to form a fully implemented work platform system as ultimately shown in  FIG. 15 . That is, although  FIG. 1  (as well as  FIGS. 2 and 3 ) shows an early stage of an implementation (installation) process of a work platform system in relation to the suspension bridge  100 , during which the work platform system takes the form of the partly implemented work platform system  110 , additional description provided below provides detail as to how the partly implemented work platform system  110  evolves into a fully implemented work platform system, which is ultimately shown in  FIG. 15 . 
     Referring additionally to  FIG. 2 , an enlarged detail view of a region or portion  150  of the side elevation view of  FIG. 1  is provided, to show a portion of the suspension bridge  100  along with an assembly  200  of the first portion  132  of the support subsystem  130  and an additional portion of the partly implemented suspended subsystem  120  of the partly implemented work platform system  110 . More particularly as shown in  FIG. 2 , in the present example in which the partly implemented work platform system  110  is being implemented in relation to the suspension bridge  100 , the first portion  132  of the support subsystem  130  is implemented so as to be attached to and supported by a respective one of the towers (or piers)  140  of the bridge, with the partly implemented suspended subsystem  120  in turn being supported by that portion  132  of the support subsystem generally at a junction  225 . Thus, in the detail view provided in  FIG. 2 , the first portion  132  of the support subsystem  130  is mounted on and supported by a first of the towers  140  of the bridge  100 , albeit it should be understood (e.g., as shown in  FIG. 1 ) that another substantially identical portion (the second portion  134 ) of the support subsystem is mounted on/supported by the other of the towers  140  (e.g., at another junction corresponding to the junction  225 ). 
     As discussed further in relation to  FIG. 3 , the first and second portions  132  and  134  of the support subsystem  130  are supported directly in relation to the towers  140  (e.g., by way of anchors as discussed below). However, in addition to such manner of support, as is evident from  FIG. 2  (as well as from  FIG. 1  upon close inspection), it should also be appreciated that in the present embodiment the first and second portions  132  and  134  of the support subsystem  130  are further supported by support chains  220 . As shown, the support chains  220 , which can be considered to constitute additional parts of the support subsystem  130 , are connected to and extend downward from locations along a deck  222  of the suspension bridge  100  to locations along the main body of the support subsystem  130  (particularly to certain structural support components thereof, as discussed further below). The support chains  220  not only allow for suspension of the support subsystem  130  (particularly the main body of that support subsystem) in relation to the deck  222  of the suspension bridge  100 , but also allow for implementation of the support subsystem  130  in relation to the suspension bridge. In particular, in the present embodiment it is envisioned that the support chains  220  are used to hoist the otherwise-fully-assembled portions  132  and  134  of the support subsystem  130  upward and into place at appropriate vertical levels along the towers  140 , where the portions  132  and  134  are then anchored into place in relation to the towers by way of anchors as discussed below. 
     Referring additionally to  FIG. 3 , a top plan, partly cross-sectional view taken along a line  3 - 3  of  FIG. 2  is provided, to further show a portion of the suspension bridge  100  in relation to the assembly  200  of  FIG. 2 .  FIG. 3  particularly illustrates features of the portions of the partly implemented work platform system  110  that are included within the assembly  200 . In this regard,  FIG. 3  shows the first portion  132  of the partly implemented support subsystem  130  as extending fully around the first of the towers  140  of the suspension bridge  100 . It will be understood that, although not shown in  FIG. 3 , the second portion  134  of the support subsystem  130 , which is provided on the other of the towers  140  of the suspension bridge, similarly extends fully around that tower in the present embodiment. Further, even though in the present embodiment the first portion  132  and second portion  134  respectively extend entirely around the respective towers  140  in relation to which those portions are respectively positioned and/or supported, in alternate embodiments the first portion and/or the second portion (or some other platform or platform portion) need not encircle the respective tower (or pier or other structure) but rather can simply be positioned along and/or supported in relation a single side or a single region or portion of the respective tower (or pier or other structure). 
     Further, the partly implemented suspended subsystem  120  in the present embodiment is shown to include multiple pairs of flexible elements  230 , such as, for example, wire tendons in the embodiment shown. More particularly, the pairs of wire tendons  230  in the present embodiment include first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth pairs of wire tendons  301 ,  302 ,  303 ,  304 ,  305 ,  306 ,  307 ,  308 , and  309 , respectively. A portion of the first pair of wire tendons  301  is shown in an additional detail view provided as  FIG. 3A  to particularly illustrate that, although pairs of wire tendons are not visible in  FIG. 3 , each of the pairs of wire tendons  230  does nevertheless include two distinct wire tendons, which run side-by-side along with one another (that is, the two wire tendons at corresponding positions along their respective lengths are at substantially the same vertical levels, as measured relative to the ground or some similar vertical or substantially vertical reference). Also, in the present embodiment, each of the wire tendons of each pair of the wire tendons is a 7/16 inch diameter wire tendon, although in other embodiments other sizes of wire tendons (e.g., ⅝ inch diameter wire tendons) can be used, with different sizes of wire tendons particularly being selected to provide desired load capacity. 
     It should be appreciated that pairs of flexible elements (e.g., wire tendons) in the present embodiment can be considered “paired” particularly in the sense that the support role played by each given tendon of the pair, in terms of supporting other structures upon it (e.g., a particular side edge of a panel section such as one of the panel sections  750  discussed below) is also performed equally or substantially equally by the other wire tendon of the pair, such that the other wire tendon plays a substantially redundant or auxiliary support role relative to the given wire tendon of the pair (and vice-versa). Through the use of pairs of redundant wire tendons, support can still be achieved for the suspended subsystem  120  even in circumstances where one of the wire tendons ceases to provide its intended support role. 
     Further with respect to the pairing of wire tendons, it should be noted that the mere presence of two wire tendons in support roles in a given suspended subsystem does not necessarily make those two wire tendons “paired” if the support roles provided by each respective wire tendon fail to be shared or overlap to a significant degree or if the support role being provided by the two wire tendons lacks any substantial qualitative similarity. For example, it would be appropriate to consider two wire tendons to be paired if both of the wire tendons support at least one component in the same or a substantially same manner (e.g., where each of two wire tendons supports the same edge of a panel section such as one of the panel sections  750  discussed below). This could be true even if the two wire tendons do not provide equal amounts of support (e.g., where one of the tendons bears 60% of the burden and the other bears 40% of the burden). Alternatively, also for example, it would not be appropriate to consider two wire tendons to be paired in a circumstance where a given one of the wire tendons supported a first side edge of a panel section but the other wire tendon supported a second opposite side edge of that panel section, and where the wire tendons otherwise did not share or substantially share any other support role (e.g., share some other support role with respect to some other component). 
     Notwithstanding the above description, it should be understood that the present disclosure is also intended to encompass numerous other embodiments employing numerous other arrangements of wire tendons. For example, in some alternate embodiments, the wire tendons of a given pair need not be arranged side-by-side (need not share common vertical levels along their lengths) but rather can be arranged above or below one another or in some other manner. Also for example, in some other embodiments, instead of employing pairs of wire tendons, single wire tendons can be employed independently (that is, employed to perform a support role that is not shared or substantially shared by any other redundant wire tendon or tendons), or groups of more than two wire tendons that are paired with one another (that is, paired in the sense described above, in terms of a shared or substantially shared support role) can be employed. Also, depending upon the embodiment, a given arrangement of paired (or independent) wire tendons can be employed repeatedly throughout the suspended subsystem in a consistent manner, as is the case with the partly implemented suspended subsystem  120  of  FIG. 3 , or alternatively differing numbers of paired (or independent) wire tendons can be employed in a varying manner at different locations in a given suspended subsystem. 
     As for the first portion  132  of the support subsystem  130 ,  FIG. 3  particularly shows that first portion of the support subsystem  130  with floor panels and suspension chains removed so as to more clearly reveal several structural support components of that first portion  132  that together form a “skeleton” of that first portion. Such floor panels (upon which work personnel and/or tools or machinery or other items can be supported and move or be moved) and suspension chains (which assist in supporting the first portion  132  relative to the suspension bridge  100 ) are shown elsewhere in  FIGS. 2, 7, and 12 , with  FIG. 7  particularly illustrating the floor panels. That said, as shown in  FIG. 3 , in the present embodiment the structural support components (that is, the “skeleton”) of the first portion  132  of the support subsystem  130  particularly include a plurality of anchors  300 , a plurality of hubs  310 , and a plurality of joists  330 , where the hubs  310  are connected with one another by way of the joists  330 . It will be appreciated from  FIG. 3  that the anchors  300  particularly to anchor or support the remainder of the support subsystem  130  in relation to the tower  140 , where there is a respective anchor positioned respectively between the tower  140  and each respective hub  310 . The anchors  300  can take a variety of forms including, for example, expansion anchors (where bolting to the tower  140  takes place) or chemical anchors (e.g., involving glue). 
     Referring to  FIGS. 4 and 5 , there is illustrated in more detail an example of one of the hubs  310 , as well as one of the hubs  310  in connection with an example of one of the joists  330 . A joist such as the joist  330  can be considered any elongate structural member adapted for bearing or supporting a load, such as a bar joist, truss, shaped-steel (i.e., I-beam, C-beam, etc.), or the like. By contrast, a hub such as the hub  310  is an interconnection structure, such as a node, hinge, pivot, post, column, center, shaft, spindle, or the like. In the present example, the hub  310  of  FIG. 4  (and, indeed, each of the hubs  310  of  FIG. 3 ) is configured so that, when attached to one of the joists  330  as shown in  FIG. 5 , the hub  310  is capable of articulation relative to the joist  330  (and vice-versa). Articulation, as used herein, is defined as the capability to swing, and/or rotate, about a pivot point or axis. This articulation feature among other things allows for less manpower to readily assemble and disassemble components of the system in, or near, the desired finished position. 
     Further as shown in  FIGS. 4 and 5 , the hub  310  includes a top element  311  and a bottom element  312  spaced at distal ends of a middle section  315 . The top element  311  and bottom element  312  can be substantially planar in configuration, as well as parallel to each other. The top element  311  and bottom element  312 , in the embodiment shown, are substantially planar surfaces that are octagonal in shape (as viewed from a plan view). The middle section  315  can be a cylindrical section where a longitudinal axis of the middle section  315  is normal to the planes of the top element  311  and bottom element  312 . In the embodiment shown, the middle section  315  is a right circular cylinder. In  FIG. 4 , a lower portion of the middle section  315  is removed for clarity (at a location  323 ) to reveal that the middle section  315  is hollow. Further as shown in  FIG. 4 , there are a plurality of openings  313 ,  314  extending through both the top element  311  and bottom element  312 , respectively. The plurality of openings  313  (e.g.,  313 A,  313 B,  313 C,  313 D,  313 E,  313 F,  313 G,  313 H) are interspersed on the top element  311  so as to offer various locations for connecting to one or more of the joists  330  (see, e.g.,  FIG. 5 ). The plurality of openings  314  (e.g.,  314 A,  314 B,  314 C,  314 D,  314 E,  314 F,  314 G,  314 H) are similarly spaced on the bottom element  312  so that respective pairs of the openings  313  and  314  (e.g.,  313 A and  314 A) are coaxial. 
     It should particularly be appreciated that, in the present embodiment, the wire tendons  230  of the partly implemented suspended subsystem  120  can also be coupled to the support subsystem  130  by coupling those wire tendons to respective ones of the openings  313  (or  314 ) of the appropriate ones of the hubs  310 . In the present embodiments, these connection locations generally constitute the junction  225  mentioned above in relation to  FIG. 2 . The actual mechanism by which coupling takes place can vary depending upon the embodiment. For example, in some embodiments, the wire tendons  230  can have looped ends, and then additional loop structures, C-bracket structures, clasping structures, or hook-type components are provided so as to extend through both the respective looped ends of respective ones of the wire tendons  230  and corresponding ones of the openings  313  (or  314 ) of the hubs  310  so as to achieve attachment. In other embodiments, any of a variety of other connective, clasping, locking, or fastening mechanisms or brackets can be employed to achieve attachment of the wire tendons  230  (and ultimately the fully completed suspended subsystem) to the support subsystem  130  at the junction  225 , and such structures can be supplemented by additional structures that facilitate a clean transition between the floor panels of the support subsystem and the corresponding floor panels of the suspended subsystem. 
     Also as shown, at the center of the top element  311  is a center opening  316 , which is configured to be able to receive a linkage or suspension connector by which the hub  310  can be suspended from another structure, such as from a deck  222  (see  FIG. 2 ) of the suspension bridge  100 . The center opening  316  can be generally cruciform in configuration with a center opening area  319  and four slots  317  (e.g.,  317 A,  317 B,  317 C,  317 D) extending therefrom. Transverse to each of the four slots  317 A,  317 B,  317 C,  317 D, and interconnected thereto, are also a series of cross slots  318 A,  318 B,  318 C,  318 D. For added strength a reinforcing plate  320  is added to the underside of the top element  311 , where openings on the reinforcing plate  320  correspond to (and are generally coextensive with) the center opening  316  configuration and all the ancillary openings thereto (e.g., the slots and area  317 ,  318 ,  319 ). A handle  322  is optionally added to a side of the middle section  315 . Although not visible in  FIGS. 4 and 5 , it should be appreciated that an identical (center) opening is formed on the bottom element  312 , and the bottom element along its top side can likewise include a reinforcing plate with the same opening. Also not shown, attached to the reinforcing plate along the bottom element  312  and the interior face of the middle section  315  can be a plurality of gussets that provide added support to the hub  310 . 
     In addition to  FIG. 5  depicting a top perspective view of the interconnection between a single one of the hubs  310  and a single one of the joists  330 , further  FIGS. 6A and 6B  show an exploded top perspective cutaway view, and a regular (unexploded) top perspective cutaway view, respectively, of a typical connection between the hub  310  and joist  330 . As shown, the joist  330  includes an upper element  332  and a bottom element  333 . Interspersed between the elements  332 ,  333  are a plurality of diagonal support members  338 . Each of the elements  332 ,  333  is made of two L-shaped pieces of angle iron  339 A,  339 B. The elements  332 ,  333  typically can be identical in construction, with the exception being that the upper element  332  includes connector holes  354 A,  354 B at its midspan. The joist  330  includes a first end  331 A and a second end  331 B. At each of the ends  331 A,  331 B of both the upper element  332  and bottom element  333 , there extends an upper connecting flange  335  and a lower connecting flange  336 . Additionally, through each of the upper and lower connecting flanges  335 ,  336 , there are connecting holes  337 . 
     Thus, given the above description, it should be appreciated that there are four upper connecting flanges  335 A,  335 B,  335 C,  335 D and four lower connecting flanges  336 A,  336 B,  336 C,  336 D, as well as four connecting holes  337 A,  337 B,  337 C, and  337 D, on the joist  330 . Accordingly, at the first end  331 A, extending from the upper element  332 , is an upper connecting flange  335 A and lower connecting flange  336 A, with a connecting hole  337 A therethrough (see both  FIG. 5  and  FIG. 6A ). Similarly, at the second end  331 B of the upper element  332 , there extends an upper connecting flange  335 B and lower connecting flange  336 B, with a connecting hole  337 B therethrough. Also, at the first end  331 A of the lower element  333  there extends an upper connecting flange  335 D and lower connecting flange  336 D. Through these connecting flanges  335 D,  336 D are a connecting hole  337 D. Further at the second end  331 B of the joist  330  extending from the lower element  333  is an upper connecting flange  335 C and lower connecting flange  336 C with a connecting hole  337 C therethrough. In addition to the respective connecting holes  337 A,  337 B,  337 C,  337 D, each of the connecting flanges  335 A,  335 B,  335 C, and  335 D additionally includes a respective additional locking hole  360 A,  360 B,  360 C,  360 D, respectively, all of which are located inwardly of the respective connecting holes (that is, axially toward the center of the joist  330  relative to the connecting holes). 
     Further as shown in  FIGS. 6A and 6B , pins  340 A can be placed through the connecting holes  337  of the connecting flanges  335 ,  336  at each of the first end  331 A and second end  331 B of the joist  330  and further through any two corresponding ones of the openings  313 ,  314  of the hub  310 .  FIGS. 6A and 6B  particularly show one of the pins  340 A employed at the first end  331 A, it being understood that the same or substantially same arrangement can be present at the end  331 B. In this manner, the joist  330  can be connected in a virtually limitless number of ways, and angles, to the hub  310 . For example, as shown particularly in  FIGS. 6A and 6B , one of the pins  340 A can be placed in through the connecting flange  335 A, through the opening  313 A, through the connecting flange  336 A (all at the first end  331 A of the upper element  332 ), through the connecting flange  335 D, through the opening  314 A, and then through the connecting flange  336 D. In this scenario, the pin  340 A further threads through connecting holes  337 A and  337 D. 
     Also as shown (particularly see  FIGS. 6A and 6B ), each of the pins  340 A additionally includes two roll pins  342  at its upper end. The lower of the two roll pins  342  acts as a stop, thereby preventing the pin  340 A from slipping all the way through the joist  330  and hub  310 . The upper roll pin  342  acts as a finger hold to allow easy purchase and removal of the pin  340 A from the joist  330  and hub  310 . The design of these various parts is such that free rotation of both the joist  330  and hub  310  is allowed, even while the joist  330  and hub  310  are connected together. Rotational arrows R 1  of  FIGS. 5 and 6B  show the rotation of the joist  330  relative to the hub  310 , while rotational arrows R 2  show the rotation of the hub  310  relative to the joist  330  of  FIGS. 5 and 6B . These rotational capabilities of the joist  330  and hub  310  relative to one another provide, in part, the articulating capability of the present design. 
     Although articulation of the joist  330  and hub  310  relative to one another can occur in some embodiments or operational circumstances, in other embodiments or circumstances such articulation is precluded. In particular, articulation is typically precluded when the work platform system is fully implemented, or even when the structural support components of the partly implemented support subsystem  130  are installed as shown in  FIG. 3 . To preclude such articulation, as shown in  FIGS. 6A and 6B , optional locking pins  340 B (one of which is shown) are installed in relation to the interfacing hubs  310  and joists  330 . More particularly as shown, locking of the hub  310  and joist  330  of  FIGS. 6A and 6B , so as to prevent relative articulation, is achieved by adding the locking pin  340 B through the locking holes  360 A and  360 D proximate the end  331 A of the joist  330 . The locking pin  340 B particularly operates to preclude such articulation (at least in part) due to contact with the hub  310  along two of several grooves (or slots/dimples)  324  formed along the perimeters of the upper element  311  and lower element  312  of the hub  310 . Because the locking pin  340 B extends through two of the grooves  324 , the locking pin effectively is prevented from moving around the perimeters of the upper and lower elements  311 ,  312  and correspondingly prevents such movement of the joist  330  relative to the hub  310 . 
     As with the pin  340 A, the locking pin  340 B can include additional two roll pins  342  as shown, which serve the same purposes as discussed above with respect to the roll pins provided on the pin  340 A. Although not shown in  FIGS. 6A and 6B , it should be likewise understood that another of the locking pins  340 B can similarly be added through the locking holes  360 B and  360 C proximate the end  331 B (see  FIG. 5 ) of the joist  330  when that end is connected to another one of the hubs  310  by another of the pins  340 A. 
     It should be appreciated that, in the present embodiment the support subsystem  130  employs components and features according to the QuikDeck™ suspended access system available from Safway Services, LLC of Waukesha, Wis., the beneficial assignee of the present patent application. As already discussed, and as further discussed below, these components of the support subsystem  130  among other things include the anchors  300 , hubs  310 , and joists  330  and related subcomponents discussed above as well as the floor panels  732  and support chains  220  further discussed below. Nevertheless, it should also be appreciated that a variety of other support subsystems and support subsystem components can also or instead be utilized depending upon the embodiment or circumstance, and such other support subsystems and associated components are also intended to be encompassed herein. 
     Among other things, the present disclosure is particularly also intended to encompass support subsystems that employ other component(s) such as any of those described in U.S. Pat. No. 7,779,599 entitled “Articulating Work Platform Support System, Work Platform System, and Methods of Use Thereof”, issued on Aug. 24, 2010, which is hereby incorporated by reference herein (said issued patent being assigned to a common assignee with the present patent application). Also, for example, notwithstanding the above description of the hubs  310 , joists  330 , and associated components shown in  FIGS. 4, 5, 6A, and 6B , it should be appreciated that these components are only example components that can be employed among the components forming the underlying/internal structural support components (or “skeleton”) of the support subsystem  130  and that other structural support components can be employed in other embodiments. Further for example, depending upon the embodiment, the support subsystem  130  can include a variety of other components in addition to, and/or instead of, the anchors, hubs, joists, floor panels, and support chains already discussed above. 
     Additionally for example, depending upon the embodiment, various differently-shaped components can be utilized. For example, while joists such as the joist  330  can be bar joists, the joists can also be open-web joists and/or structural tubing. Further for example, one or more of the joists  330  can be made of multiple pieces of structural tubing shapes, or the joists  330  can be one single structural tubing shape. Similarly, the joist  330  could be made of shaped steel (e.g., wide flange elements, narrow flange members, etc.), or other suitable shapes and materials. Also, additionally other types of joists that are curved rather than linear (straight) can be employed, as can other types of panel portions and supports for such panel portions. Further, although in the present embodiment it is envisioned that the first and second portions  132  and  134  of the support subsystem  130  (including all hubs, joists, anchors, floor panels, and support chains thereof) will be fully assembled and installed in relation to the towers  140  prior to any portions of the suspended subsystem (e.g., the partly implemented subsystem  120 ) being implemented, in alternate embodiments it is possible that portions of the support subsystem  130  will be implemented contemporaneously with, or subsequent to, implementation of the suspended subsystem. 
     Turning now to  FIG. 7 , a top plan, partly cross-sectional view of an assembly  700  of portions of a further implemented work platform system  710  corresponding to (that is, portions of the system which would be positioned in) the region  150  of  FIG. 1  is shown. The particular view provided by  FIG. 7  is one taken along line  7 - 7  of  FIG. 12 , which as discussed further below shows an additional enlarged detail view of a side elevation view of the assembly  700  in combination with portions of the suspension bridge  100  corresponding to the region  150  of  FIG. 1 . The further implemented work platform  710  should be understood particularly to be the partly implemented work platform system  110  of  FIGS. 1-3  as further modified to include additional components. In particular, the portions of the further implemented work platform system  710  shown in  FIG. 7  include both the support subsystem  130  discussed above as well as portions of a further implemented suspended subsystem  720 , which is the partly implemented suspended subsystem  120  after being modified to include additional components. 
     Although the support system  130  appears somewhat different in  FIG. 7  by comparison with  FIG. 3 , this is merely because  FIG. 7  now shows panel sections  732  that are supported upon the hubs  310  and joists  330  (the “skeleton”) of the support structure that were shown and discussed in relation to  FIG. 3 . As already mentioned above, the panel sections  732  effectively provide a floor upon which work personnel can walk and on which equipment and components can be transported and supported. Notwithstanding this difference in appearance, it should nevertheless be understood that the support subsystem  130  of  FIG. 7  is the same as that shown in  FIG. 3 , as well as the same as that shown in  FIGS. 2 and 12 , and thus particularly includes all of the hubs  310 , joists  330 , and anchors  300  shown in  FIG. 3  as well as the panel sections  732  and the support chains  220  shown and discussed in relation to  FIGS. 2 and 12 . It should additionally be understood that, although the support subsystem  130  is considered be a fully implemented or installed support structure for the present embodiment, in other embodiments additional components not shown in  FIG. 7  (or in  FIG. 2, 3 , or  12 ), such as railings, can still be added to the support subsystem  130  and that the support subsystem would only be complete after such additional components are implemented. 
     With respect to the further implemented suspended subsystem  720 , as shown in  FIG. 3  this suspended subsystem differs from the partly implemented suspended subsystem  120  of  FIG. 3  particularly insofar as the subsystem  720  includes multiple panel sections  750  that have been installed so as to be supported upon the various pairs of wire tendons  230 . More particularly as shown, given the presence of the nine pairs of wire tendons  230  (that is the pairs of wire tendons  301 ,  302 ,  303 ,  304 ,  305 ,  306 ,  307 ,  308 , and  309 ), there are shown to be eight partly completed rows of the panel sections  750 , namely, first, second, third, fourth, fifth, sixth, seventh, and eighth rows  751 ,  752 ,  753 ,  754 ,  755 ,  756 ,  757 , and  758 , where each respective one of the rows (e.g.,  751 ,  752 , etc.) is supported upon a corresponding pair of successive ones of the pairs of the wire tendons  230  (e.g., the pairs  301  and  302 , the pairs  302  and  303 , etc.). It should be appreciated that the actual number of rows of panel sections  750 , as well as the actual number of pairs of wire tendons  230 , can vary depending upon the embodiment. For example, in some other embodiments, there is only a single row of the panel sections  750  positioned on and between two pairs of the wire tendons  230 , while in other embodiments, there can be more than or less than eight rows of panel sections and more than or less than nine pairs of wire tendons. 
     Turning now to  FIGS. 8A, 9, and 10 , a top plan view, side elevation view, and right end side elevation view of an example one of the panel sections  750  of  FIG. 3  are respectively shown. For example,  FIGS. 8A, 9, and 10  can be considered to show a panel section  765  shown in  FIG. 3 , which is the rightmost panel section of the sixth row  756  of panel sections, and which can be considered identical to each of the other panel sections  750  shown in  FIG. 3 . As illustrated, the panel section  765  is generally in the shape of an elongated rectangle, and in the present embodiment has a width dimension  759  of 92 inches (or about eight feet) and a length dimension  761  of 24 inches (two feet). For purposes of the present discussion, the width dimension  759  corresponds substantially to the distance between neighboring ones of the pairs of wire tendons, between which the panel section  765  extends, and the length dimension  761  by contrast corresponds to the length of the panel section  765  along the wire tendons (albeit in other embodiments length and width dimensions can be defined differently). 
     In other embodiments, these dimensions of any one or more of the panel sections that are employed in a given suspended subsystem can vary from those shown with respect to the panel section  765 . For example, in another embodiment, the panel section can be approximately eight feet long by one foot wide. Indeed, the panel section need not be an elongated rectangle but also could be another shape, such as that of a square. Additionally, although not shown in  FIG. 7 , in some embodiments different panel sections having different sizes (and/or shapes) can be implemented in the same work platform system. For example, certain of the panel sections can have the two feet by eight feet dimensions stated above, and others of the panel sections in the same work platform system can have one foot by eight feet dimensions. Through the use of panel sections of varying dimensions (e.g., different length and/or width dimensions), a variety of practical issues associated with the implementation of the work platform system can be conveniently addressed. For example, if one or more obstacles (e.g., a pipe jutting beneath the deck  22 ) precludes the implementation of one of the panel sections  750  along one of the rows of panel sections, it can still potentially be possible for a panel section of a different size to be implemented instead. 
     As an example, the panel section  765  particularly includes a top panel surface  763  having dimensions that are equal to the previously-mentioned width and length dimensions  759  and  761  of the overall panel section  765 , and that is the surface upon which work personnel can walk. In the present embodiment, the top panel surface  763  is made of wood (e.g., plywood). Use of wood as the top panel surface  763  can be particularly advantageous in that surface provides better traction even during conditions where moisture exists on the surface (e.g., during a rainstorm) than if other materials such as sheet metal were used. Nevertheless, the particular material employed to form the top panel surface  763  can vary depending upon the embodiment. 
     Further with respect to the panel section  765 , the top panel surface  763  is mounted upon steel tubes or struts  760 , which are shown in each of  FIGS. 8A, 8B, 9, and 10  (the struts are shown in phantom particularly in  FIGS. 8A and 8B ), and which form a support structure or “skeleton” underlying the panel surface  763 . Additionally as shown, the struts  760  particularly include a pair of side struts  762 , a pair of end struts  764 , and a supporting strut(s)  766 . The side struts  762  and end struts  764  effectively form a loop that follows along the perimeter of the panel surface  763 , with the side struts  762  extending the full length of the width dimension  759  and the end struts  764  extending the full width of the length dimension  761 . The supporting strut(s)  766  is positioned underneath the panel surface  763  so as to extend between the two side struts  762 . 
     As shown in  FIG. 8A , the struts  760  forming the underlying support structure (i.e., side struts  762 , end struts  764  and supporting struts  766 ) can have the same shape, thickness and inner and outer dimensions. In other embodiments, struts  760  can have different shapes, thicknesses, and outer and inner dimensions. For example, in one embodiment, the side struts  762  and end struts  764  can be square tubular steel while supporting struts  766  can be rectangular tubular steel. 
     In the embodiment shown in  FIG. 8A , the panel section  765  contains a single supporting strut  766  positioned midway between the end struts  764 . In the embodiment shown in  FIG. 8B , the panel section  765  contains two supporting struts  766  evenly positioned between end struts  764 . As illustrated through  FIGS. 8A and 8B , more or fewer supporting struts  766  can be used to support the panel surface  763 , and the number and positioning of supporting struts  766  can depend on the material, weight, strength and/or thickness of panel surface  763 . For example, in one embodiment, a single supporting strut  766  can be used with a panel surface  763  having a ½-inch thickness, while two supporting struts  766  can be required with a panel surface  763  having a ⅜-inch thickness. 
     In addition to the top panel surface  763  and the struts  760 , the panel section  765  additionally includes several support components that extend outward from the struts  760  and allow for the mounting of the panel section  765  in relation to the wire tendons  230  and also in relation to other ones of the panel structures  750  as shown in  FIG. 7  (e.g., so as to form the rows of panel sections). More particularly as shown, these support components include four wire tendon support extensions  770  as well as four handle support extensions  780 , all of which extend outward beyond the confines of either the width and length dimensions  759  and  761  mentioned above. As shown, the wire tendon support extensions  770  particularly extend outward away from the end struts  764 , that is, outward along directions that are parallel or substantially parallel to the width dimension  759 . Two of the wire tendon support extensions  770  extend outward generally at opposite ends of one of the side struts  762 , and the other two of the wire tendon support extensions  770  extend outward generally at opposite ends of the other of the side struts  762 . By contrast, the handle support extensions  780  extend outward from the side struts  762  in directions parallel or substantially parallel to the length dimension  761 , and are all positioned at locations well inward of the end struts  764 . 
     As is evident from  FIGS. 8A and 8B , the wire tendon support extensions  770  include small bends  774  such that outer portions  776  of the extensions  770  are shifted slightly relative to inner portions  778  by which the extensions  770  are affixed to the end struts  764 . More particularly, in the present embodiment, each of the wire tendon support extensions  770  extending from a first one of the end struts  764  (e.g., the right end strut shown in  FIG. 8A ) has a respective outer portion  776  that is offset or shifted in a first direction along the length dimension  761 , and each of the wire tendon support extensions  770  extending from the other one of the end struts  764  (e.g., the left end strut shown in  FIG. 8A ) has a respective outer portion  776  that is offset or shifted in a direction opposite that of the first direction. Such oppositely-directed offsets (or “joggles”) of the outer portions  776  that are at opposite ends of the panel section  765  are complementary so as to make it possible for two of the panel sections  750  in neighboring ones of the rows (e.g., two panel sections that are respectively positioned, side by side, in the rows  756  and  757  of  FIG. 7 ) to be supported upon a shared pair of the wire tendons  230  (e.g., by the pair of wire tendons  307 ) and also to be aligned such that the corresponding side struts  762  of each of the panels sections are exactly aligned with one another. Thus, in  FIG. 7 , the rows  751 ,  752 ,  753 ,  754 ,  755 ,  756 ,  757 , and  758  of the panel sections  750  are shown to be completely aligned with one another. 
     Further as illustrated, particularly in  FIG. 9 , each of the wire tendon support extensions  770  and particularly the outer portions  776  thereof includes a pair of indentations  772  that extend upward from a bottom ridge of those portions. It is by virtue of these indentations  772  that the outer portions  776  of the wire tendon support extensions  770  can be slipped over and onto the two pairs of wire tendons  230  between which the panel  750  is to be positioned. Thus, for example, continuing to assume that the panel section  750  of  FIGS. 8A, 8B, 9, and 10  is the panel section  765  of  FIG. 7  that is the rightmost one of the panel sections of the sixth row of panel sections  756 , then the indentations  772  of the leftward one of the outer portions  776  shown in  FIG. 9  can be considered to be the indentations that receive (slip over) the pair of wire tendons  307 , and the indentations  772  of the rightward one of the outer portions  776  shown in  FIG. 9  can be considered to be the indentations that receive (slip over) the pair of wire tendons  306 . 
     In addition to the above features, it will be observed from  FIG. 9  that in the present embodiment each of the wire tendon support extensions  770  also includes an orifice or notch  781 , positioned generally in between the indentations  772  of the respective wire tendon support extension. By virtue of the presence of the orifices  781  of the wire tendon support extensions, in some embodiments, additional structures such as guard rail posts or wires or other structures (not shown) can be affixed to the wire tendon support extensions and thus to the remainder of the suspended subsystem. 
     Notwithstanding the above discussion concerning the wire tendon support extensions  770 , it should be appreciated that those extensions (or similar structures employed to allow the panel sections  750  to be supported upon flexible support elements such as the wire tendons  230 ) can take on different forms in other embodiments. For example, in some alternate embodiments, the wire tendon support extensions do not have any offsets (or “joggles”). That is, in such embodiments, the wire tendon support extensions are straight such that the inner and outer ends (that is, the portions of the wire tendon support extension corresponding to the inner and outer portions  778  and  776  discussed above) are aligned. The offsets (or “joggles”) need not be employed in all embodiments, since the thickness of the wire tendon support extensions can be small, and since there is not always any particular need that panel sections provided in rows on opposite sides of a given pair of wire tendons be fully aligned (that is, so that the side struts  762  of panel sections in different rows are lined up). 
     Further in some alternate embodiments one or more subfeatures of one or more the wire tendon support extensions can take a form different than those discussed above with respect to  FIGS. 8A, 8B, 9, and 10 . For example, in one alternate embodiment, one or more of the wire tendons support extensions of a panel section can take the form of a wire tendon support extension  770 A shown in  FIG. 9A , which for comparison purposes is shown to correspond to a portion of one of the wire tendon support extensions  770  of  FIG. 9 . In this example, rather than having the two indentations  772  that are identical in shape, instead the wire tendon support extension  770 A has a first indentation  772 A and a second indentation  772 B that are somewhat different in shape, with the second indentation  772 B identical or substantially identical to the indentations  772  of  FIG. 9  but the first indentation  772 A having an additional cutout region  783 A expanding the indentation beyond the size and shape of the indentations  772  of  FIG. 9 . The expanded size of the first indentation  772 A with the additional cutout region  783 A allows, in at least some embodiments, easier mounting of the wire tendon support extension  770 A onto pairs of wire tendons such as the wire tendons  230 . Also it can be noted that, in the alternate embodiment of  FIG. 9A , the wire tendon support extension  770 A includes an orifice  781 A corresponding to the orifice  781  of one of the wire tendon support extensions  770  of  FIG. 9  except insofar as the orifice  781 A is positioned lower and closer to the second indentation  772 B than to the first indentation  772 A (at least when compared to the uppermost tips of the two indentations) to accommodate the presence of the additional cutout region  783 A of the first indentation  772 A. Notwithstanding the above description concerning  FIGS. 9 and 9A , it should be understood that the wire tendon support extensions can be modified in other manners as well. For example, in some additional embodiments, additional holes (e.g. in addition to the orifice  781  or orifice  781 A can be added to facilitate fixturing and/or for use on scaffold arrangements of other sizes). 
     Referring still to  FIGS. 8A, 8B, 9, and 10 , the handle support extensions  780  take a different structural form than the wire tendon support extensions  770  insofar as each of the extensions  780  is a looping structure that extends outward away from one of the side struts  762  (outward away from the top panel surface  763 ), then extends sideways generally parallel to the side struts so as to form a respective intermediate handle portion  779 , and then loops back so as to connect up again with the respective side strut from which it originally extended (at a different location along that side strut). In this sense, each of the handle support extensions  780  is a U-shaped extension. Further as evident from  FIG. 10 , when the panel section  765  is viewed from the right end side (or the left end side), it becomes apparent that each of the handle support extensions  780  not only is U-shaped but also has an L-shaped characteristic. More particularly as shown, each of the handle support extensions  780  juts outward from the respective side strut  762  on which it is mounted, in a generally horizontal manner (that is, parallel to the top panel surface  763 ), but then extends further to include a hook-like formation  785 , at which the respective handle support extension first dips down (that is, away from the top panel surface) slightly and then curves back upward (that is, toward the plane of the top panel surface) to a location at which the intermediate handle portion  779  of the extension is formed. In the present embodiment, the respective intermediate handle portions  779  of the respective handle support extensions  780  are at respective locations that are substantially higher than the respective locations at which the respective handle support extension  780  first extend horizontally outward. 
     The particular hook-shaped configuration of the handle support extensions  780  of each of the panel sections  750  such as the panel section  765  serves several purposes. To begin, shape of the handle support extensions  780  allows those extensions to serve as handles by which work personnel (or other installation equipment) can grasp and support (and thus lift and move) the panel sections  750  during implementation of the work platform system. Additionally, the shape and positioning of the handle support extensions  780  (as discussed further below) allows for adjoining ones of the panel sections  750  in any given row of the panel sections to be easily positioned in relation to one another and ultimately interlocked with one another. Indeed, due to this interlocking of panel section sections of a given row afforded by the handle support extensions  780 , in combination with the weight of the panel sections themselves, the panel sections  750  in the present embodiment can generally be supported and mounted onto the pairs of wire tendons  230  (with the indentations  772  receiving the pairs of wire tendons) without any additional securing mechanisms that would tend to preclude lifting of the panel sections off of the wire tendons. That is, the panel sections  750 , once in place, are not positively locked to the wire tendons but merely remain in place relative to those tendons because of their weight and their interconnections with neighboring panel sections. That said, it should also be appreciated that, in alternate embodiments, the panel sections  750  can include other features by which the panel sections are positively locked or secured to the pairs of wire tendons on which those panel sections are supported. 
     Further in regard to the installation and interlocking of the panel sections  750  such as the panel section  765 ,  FIGS. 11A, 11B, and 11C  respectively provide first, second, and third partially cutaway schematic views of an additional panel section  791  (which is of the same type as each of the panel sections  750 ) being installed in relation to the panel section  765  that has already been positioned onto the wire tendons  230  (e.g., on to the sixth and seventh pairs  306  and  307  of the wire tendons), so that the additional panel section  791  likewise is positioned onto and supported by those wire tendons. More particularly, each of  FIGS. 11A, 11B, and 11C  is a cross-sectional view that is taken through both of the panel sections  765  and  791 , along a line that corresponds to a line  11 - 11  shown in  FIG. 8  with respect to the panel section  765 , where as shown in  FIG. 8  the line  11 - 11  cuts through one of the handle support extensions  780  of the panel section  765  that is along that one of the side struts  762  of that panel section adjacent to which the additional panel structure  791  is to be placed. Further in this regard, it should be understood that, although  FIG. 8  does not show also the additional panel section  791 , the cross-sectional view that is provided in  FIGS. 11A, 11B, and 11C  is that which would be appropriate given a typical installation process of the additional panel section  791  in relation to the panel section  765  in which the end struts  764  of the two panel sections are aligned with one another. 
     More particularly,  FIG. 11A  shows how, when the additional panel section  791  is first being installed in relation to the panel section  765 , the additional panel section  791  is first positioned (e.g., by work personnel lifting the panel section  791  into place using the handle support extensions  780 ) so that the top panel surface  763  of the additional panel section  791  is received into and extends substantially vertically upward from the two co-aligned handle support sections  780  of the panel section  765 . When positioned in this manner, a first of the side struts  762  of the additional panel section  791  is positioned into the hook formations  785  of the handle support extensions  780  of the first panel section  765  into which the additional panel section  791  has been received. Also, in this initial position, the top panel surface  763  extends downward to the handle support extensions  780  of the panel section  765  (or almost to those handle support extensions) and extends in between the neighboring side struts  762  of the panel sections  765  and  791 ). 
     Turning to  FIGS. 11B and 11C , respectively, upon the additional panel section  791  being positioned into place relative to the panel section  765  as shown in  FIG. 11A , then further installation of the additional panel section  791  occurs by rotation of that panel section  791  in a direction generally indicated by an arrow  792  of  FIG. 11B , that is, rotation generally downward and outward away from the panel section  765 , up until such time as the additional panel section  791  is fully in place such that the top panel surface  763  of that panel section is horizontal and parallel to the top panel surface  763  of the panel section  765 . When such rotational movement is fully completed, it will be appreciated that both of panel sections  765  and  791  are then supported upon the wire tendons  306  and  307  between which those panels both extend, by way of the wire tendon support extensions  770  formed on each of those panels (as discussed above with respect to  FIGS. 8 and 9 ). Also, upon full installation, the neighboring side struts  762  of the panel sections  765  and  791  generally adjoin one another. 
     It will be appreciated that, to allow for proper rotation of the additional panel section  791  relative to the panel section  765 , the handle support extensions  780  necessarily extend outward away from the side strut  762  of the first panel section  765  on which those handle support extensions are mounted by a distance that is somewhat in excess of the cross-sectional width of the side struts  762  of the additional panel section  791 , with such an excess distance being shown in  FIG. 11C  as a distance  794 . It will further be appreciated that, following proper and full installation, panel section  765  assembled in side-by-side relation will be at least partially restricted in movement in at least one of the side-to-side and up-and-down directions, more preferably in both the side-to-side and up-and-down directions, as a result of the interconnection of handle support extensions. Handle support extensions, in combination with tendon support extensions  770  (not shown), therefore at least partially, preferably completely, limit movement of fully installed panel sections in side-by-side relation in all three axes of movement, that is, side-to-side, up-and-down, and front-to-back. In some embodiments, therefore, panel sections  765  are secured to tendons and each other without the necessity of additional locks or securing structures, mechanisms or devices. 
     Further as shown in  FIG. 11C  (although not shown in  FIGS. 11A and 11B ), the additional panel section  791  includes handle support extensions  780  just as does the panel section  765 . Given that the spacing of the handle support extensions  780  on each of the panel sections  765 ,  791  is the same as that shown in  FIG. 8  (which is representative of the features of each of the panel sections  750  including the panel sections  765  and  791 ), it should be recognized that the handle support extensions  780  on one of the side struts  762  of each of the panel sections  750  are offset in a first direction, relative to the middle strut  766  of the respective panel section, but that the handle support extensions  780  on the opposite one of the side struts  762  of the respective panel section  750  are offset from the middle strut in the opposite direction. That is, the handle support extensions  780  along the top one of the side struts  762  as shown in  FIG. 8  are offset to the right while the handle sections along the bottom one of the side struts  762  are offset to the left. More particularly, in the present example embodiment of the panel section  765  as shown in  FIG. 8 , the leftmost portion of the left handle support extension  780  extending from the upper one of the side struts  762  is offset thirty-two inches from the left side edge of that panel section, which is also the left side edge of the left one of the end struts  764 , and the leftmost portion of the right handle support extension  780  extending from that side strut is offset over another twenty-eight inches from the leftmost portion of that left handle support extension. By contrast, the rightmost portion of the right handle support extension  780  extending from the lower one of the side struts  762  is offset thirty-two inches from the right side edge of that panel section, which is also the right side edge of the right one of the end struts  764 , and the rightmost portion of the left handle support extension extending from that side strut is offset over another twenty-eight inches from the rightmost portion of that right handle support extension. 
     Given this arrangement of the handle support extensions  780  on each of the panel sections  750 , it should be appreciated that the handle support extensions  780  of each of the panel sections  750  are substantially complementary. That is, due to the oppositely-shifted arrangements of the handle support extensions  780  on opposite sides of each of the panel sections  750 , neighboring panel sections can be positioned next to one another in a manner in which, instead of the handle support extensions  780  of the neighboring panel sections encountering and obstructing one another, the handle support extensions  780  of each of the neighboring panel structures serves to engage or mesh with the other of the neighboring panel structures. For example, when one of the panel sections  750  such as the additional panel section  791  is implemented in relation to another of the panel sections such as the panel section  765  as shown in  FIG. 11C , the handle support extensions  780  on the side of the panel section  765  facing the additional panel section  791  extend under and up and around the adjoining side strut  762  of the additional panel section  791 , and likewise the handle support extensions  780  on the side of the panel section  791  facing the panel section  765  (as shown in phantom in  FIG. 11C ) extend under and up and around the adjoining side strut  762  of the panel section  765 . 
     Although the panel section  765  shown in  FIGS. 8, 9, and 10  and again in  FIGS. 11A, 11B, and 11C  is one example type of panel section that can be employed in a suspended subsystem such as the further implemented suspended subsystem  720 , as already discussed it should be appreciated that depending upon the embodiment or circumstance numerous types of panel sections having many different types of features can be employed. In addition to variations in the overall sizes, dimensions, or shapes of the panel sections that are employed, which can vary with the particular suspended subsystem and even vary in the context of a given suspended subsystem, it is also possible for features of the panel sections such as the handle support extensions to vary as well.  FIGS. 11D, 11E, 11F, 11G, 11H, 11I, 11J, 11K, 11L, and 11M  are several examples of alternative panel sections  850 ,  856 ,  860 ,  870 ,  880 ,  885 ,  888 , and  890  having certain features differing from those of the panel section  765 . More particularly, as shown, in these example embodiments, each of the alternative panel sections includes wire tendon support extensions  770  substantially identical to those of the panel section  756 , but instead have different types or arrangements of handle support extensions and/or complementary components for interfacing handle support extensions. 
     More particularly in this regard, referring to  FIG. 11D , a perspective view is provided of the alternative panel section  850 , which is substantially identical to the panel section  765  except insofar as, although the alternative panel section  850  includes a pair of the handle support extensions extending from a first side  852  of the alternative panel section, no other handle support extensions are provided on the opposite side  854  of the alternative panel section. Additionally, rather than employing the hooked type of handle support extensions  780  present in the panel section  756 , the alternative panel section  850  employs handle support extensions  851  that differ from the handle support extensions in that the handle support extensions merely extend outward from the side  852  horizontally and then experience an upward 90 degree bend, as is shown particularly well in  FIG. 11G , which is discussed further below. 
     Further, referring to  FIG. 11E , a perspective view is provided of the alternative panel section  856 , which is substantially identical to the alternative panel section  850  except insofar as, although the alternative panel section  856  includes a pair of the handle support extensions  851 , one (rather than two) of those handle support extensions is provided on a first side  858  of that alternative panel section and the other of those handle support extensions is provided on an opposite side  859  of that alternative panel section. Additionally, referring to  FIG. 11F , a perspective view is provided of the alternative panel section  832 , which is substantially identical to the alternative panel section  856  except insofar as the alternative panel section  832  only includes a single one of the handle support extensions  851  along a first side  861  (positioned generally at the middle of that side), but no handle support extension along an opposite side  864 . 
     Although the type, number, and positioning of the handle support extension(s)  851  in each of the alternative panel sections  850 ,  856 , and  832  varies from that of the panel section  756 , it should be appreciated that the handle support extension(s) in each of these alternative panel sections still can perform to at least some extent the functions performed by the handle support extensions  780  in the panel section  756  (and the panel section  791 ) as illustrated in  FIGS. 11A, 11B, and 11C . The handle support extension(s)  851  can still be used for carrying and moving of the alternative panel sections  850 ,  856 , and  832  (as shown in  FIGS. 11D-11G ). Also, the handle support extension(s)  851  can further serve (at least to some extent) to orient, capture and support adjacent panel sections. For example, as illustrated in  FIG. 11G , which illustrates in a cross-sectional, partly cutaway view two of the alternative panel sections  850  of  FIG. 11D  in an assembled positioned adjacent to one another side-by-side (as if in a row of the panel sections), it is still the case in such an embodiment that the handle support extensions  851  extending from the opposite side  852  of one of those alternative panel sections will extend under, up, and around a neighboring side strut  862  of the other of those alternative panel sections  832 , and thus serve to at least partly hold in place and support that other panel section. 
     Further, with respect to  FIG. 11H , the alternative panel section  870  by contrast with the alternative panel section  850  of  FIG. 11D  includes a pair of handle support extensions  872  extending from a first side  874  that, in contrast to the handle support extensions  851 , have no bends at all but rather merely are U-shaped structures extending out purely horizontally from the first side  874 . Additionally, on an opposite side  878  of the alternative panel section  850 , rather than having any handle support extensions of any type, instead that alternative panel section includes a pair of complementary interlocking devices or protrusions  876 . As shown, each of the respective interlocking devices  876  is aligned, along the opposite side  878 , with a respective one of the handle support extension  872  positioned on the first side  874 , and the interlocking devices  876  are sized and configured so that protruding portions of the interlocking devices will respectively fit within complementary interior orifice regions of the handle support extensions  872  of another one of the alternative panel sections  870  when two such alternative panel sections are assembled. 
     Such an arrangement is shown in  FIG. 11I , which provides a side elevation view of two of the alternative panel sections  870  of  FIG. 11H  positioned adjacent to one another side-by-side (as if in a row of the panel sections). As illustrated, the interlocking devices  876  along the opposite side  878  of one of the alternative panel sections  870  are received within, and extend through and beneath, respective ones of the handle support extensions  872  positioned on the first side  874  of another of the alternative panel sections. Given such positioning of the interlocking devices  876  within the handle support extensions  872 , the two alternative panel sections  870  are interconnected with one another. Further, as with the handle support extensions  780  and  851 , the handle support extensions  872  again serve both as handles to facilitate carrying and moving of the alternative panel sections  870 , but also serve to support the adjacent alternative panel section. For example, as illustrated in  FIG. 11I , the handle support extensions  872  receiving the interlocking devices  876  also extend beneath a neighboring side strut  879  of the alternative panel section associated with those interlocking devices. 
     Although the alternative panel section  870  shown in  FIGS. 11H and 11I  is one example of an alternative panel section employing the handle support extensions  872  that are flat, the alternative panel sections  880 ,  885 ,  888 , and  892  respectively shown in respective  FIGS. 11J, 11K, 11L, and 11M  are additional examples in this regard. In contrast to the alternative panel section  870 , however, none of the alternative panel sections  880 ,  885 ,  888 , and  892  include any of the interlocking devices  876 . More particularly,  FIG. 11H  shows a perspective view of the alternative panel section  880 , and shows that panel section as having only one of the handle support extensions  872  extending from a first side  882  (generally from a middle location along that side) but having no other handle support extension  872  extending from an opposite side  883 . By contrast,  FIG. 11K  shows the alternative panel section  885  as having one of the handle support extensions  872  extending from a first side  884  and another of the handle support extensions  872  extending from an opposite side  886 ,  FIG. 11L  shows the alternative panel section  888  as having two of the handle support extensions  872  extending from a first side  887  but no handle support extensions extending from an opposite side  889 , and  FIG. 11M  shows the alternative panel section  892  as having two of the handle support extensions  872  extending from a first side  890  and another two of the handle support extensions  872  extending from an opposite side  894 . 
     It should be appreciated that, as with the handle support extensions  780  of the panel section  756 , the pairs of the handle support extensions  872  extending from the first and opposite sides  892  and  894  of the alternative panel section  890  of  FIG. 11M  are offset from one another along the lengths of those respective sides, so as to be complementarily positioned to facilitate the positioning of multiple ones of the alternative panel sections  890  side-by-side. Likewise, as with the handle support extensions  851  of the alternative panel section  856  of  FIG. 11E , the handle support extensions  872  of the alternative panel section  885  of  FIG. 11K  are offset from one another along the lengths of the sides  884  and  886  so that the handle support extensions on the opposite sides are positioned complementarily. 
     Turning now to  FIGS. 11N, 11O, 11P, 11Q and 11R , a further alternative panel section  1000  is shown. Alternative panel section  1000  includes gravity latch  1010 . Gravity latch  1010 , shown in the up position in  FIGS. 11N and 11O , is joined with tendon extensions  770  at pivot point  1015 . Gravity latch  1010  includes a tendon-engaging portion  1012  configured to directly or indirectly engage tendons  230  when in a down position as shown in  FIGS. 11P and 11Q , and extension  1013  with securing aperture  1014  and upper surface  1016 . In the exemplary embodiment illustrated, tendon-engaging portion  1012  has a C-shape or configuration. 
     Gravity hook  1010  is specifically designed with a center of gravity A which is just offset from pivot point  1015  when in both the up position and down position, as illustrated in  FIGS. 11P and 11Q . In  FIGS. 11O and 11R , the center of gravity A is indicated using a circular marking solely to reference the area A. Embodiments of gravity hook  1010  may or may not include a visible or physical indication of the center of gravity. 
     Because the center of gravity A is offset from pivot point  1015  when in both the up and down positions, gravity hook  1010  will stay in the up position until hook  1010  is physically rotated such that the center of gravity A passes to the other side of pivot point  1015 . Similarly, gravity hook  1010  will stay in the down position until hook  1010  is physically rotated such that the center of gravity A passes back over pivot point  1015 . Gravity hook  1010  therefore acts to prevent upward movement of panel sections  750  relative to tendons  230 . 
     Aperture  1014  of extension  1013  is configured to correspond to aperture  1017  of tendon extension  770 . For added stability, a securing component, such as a zip-tie, bolt, or other structure, can be secured through apertures  1014 ,  1017 , thereby physically connecting gravity hook  1010  and tendon extension  770  at a second point, the first being pivot point  1015 . Similarly, notch  1018  of tendon extension  770  is configured to correspond to the location of upper surface  1016  when gravity hook is the down position, allowing an additional cover structure (discussed below) to be installed between panel sections  750  over gravity hook  1010 . Notch  1018  also allows access to upper surface  1016  to pivot gravity hook  1010  from a down position to an up position. 
     For example, as illustrated in  FIGS. 11N, 11O, 11P and 11Q , upper surface  1016  is configured to provide a graspable area or contact area for manipulating gravity hook  1010 . For example, when in the up position, upper surface  1016  can be pushed, such as with a toe strike or by hand, to pivot gravity hook  1010  to its down position. When in the down position, upper surface  1016  protrudes above notch  1018  so that gravity hook  1010  can be returned to its up position such as by manipulating the hook  1010  by foot or grasping upper surface  1016  by hand. 
       FIG. 11R  illustrates the gravity hook  1010  in further detail. As shown in  FIG. 11R , tendon engaging portion  1012  includes an inclined surface  1020 . Under uplift conditions (i.e., under tendon pull force  1030 ), angled surface  1020  causes gravity hook  1010  to rotate clockwise (relative to the view shown in  FIG. 11R ), thereby keeping the gravity hook  1010  in a closed position. 
     The location of the center of gravity A and pivot point  1015  also serves to keep gravity hook  1010  closed under uplift conditions. Specifically, in the closed position, center of gravity A is offset from the center of pivot point  1015  at a distance of  1024  and also set below the center of pivot point  1015 . The position of the tendon  230  is also offset from the center of pivot point  1015 . As a result, under uplift conditions (i.e., under tendon pull force  1030 ), gravity hook  1010  is rotated in a clockwise position and remains closed. 
     It should be appreciated that the panel section  1000  described above can have any configuration of handle support extensions as discussed herein. Additionally, it should be appreciated that the examples of alternative panel sections discussed above are merely examples and that numerous other variations of panel sections can be implemented in embodiments encompassed by the present disclosure. 
       FIGS. 11S and 11T  illustrate modified tendon extension  770   a ′ and  770   b ′ for use with panel  1000  and gravity latch  1010 . Modified tendon extensions  770   a ′ and  770   b ′ provide support and stability when stacking unassembled panel sections  1000 . As illustrated in  FIGS. 11S and 11T , modified tendon extensions  770   a ′ and  770   b ′ include contoured portions  771   b , making tendon extension  770   a ′ distinctly a right-side tendon extension and tendon extension  770   b ′ distinctly a left-side tendon extension. In other words, tendon extensions  770   a ′ and  770   b ′ are mirror images of each other. 
       FIG. 11T  shows modified tendon extension  770   a ′ in more detail. As shown, contoured portion  771   b  angles away from the body  771   a  of tendon extension  770   a ′ and the plane of the panel section  1000 . When panel sections  1000  are stacked on top of one another (such as for storage or transport, for example), respective right and left tendon extensions  770   a ′,  770   b ′ on adjacently stacked panel sections engage each other in an overlapping fashion to prevent or limit movement (e.g., side-to-side movement) of the panels  1000  during storage and transport. 
       FIG. 11U  shows an alternative embodiment of a gravity latch  1010 ′. Gravity latch  1010 ′ functions the same as described with reference to  FIGS. 11N-11R , but has a more hook-shaped tendon engaging portion  1012 ′. In some embodiments, as shown in  FIG. 11U , gravity latch  1010 ′ includes receiving aperture  1019 ′ for engaging a protuberance and a toe board. 
     Returning to  FIG. 7  and further turning to  FIGS. 7A and 7B , full implementation of the suspended subsystem includes not only implementing the panel sections  750  onto the wire tendons  230 , but also involves implementation of additional components as well. To illustrate these additional components,  FIG. 7A  provides a detail view of a region  961  of  FIG. 7  particularly focused upon a location at which several of the panel sections  750  of each of two neighboring rows of the panel sections  751  and  752  are supported upon an intermediate pair of the wire tendons  230 , namely, the wire tendons  302 . Further,  FIG. 7B  is also provided to show the same region (region  961 ) as shown in  FIG. 7A , as that region would be seen from underneath (that is,  FIG. 7A  is a top plan view of the region  961  while  FIG. 7B  is a bottom plan view of that region or substantially the same region). 
     From  FIGS. 7A and 7B , it should particularly be evident that, due to the configuration of the panel sections  750  and the wire tendon support extensions  770 , the top panel surfaces  763  of the panel sections do not cover over the supporting wire tendons  302 , but rather there is a space or gap between the top panel surfaces of the panel sections  750  of neighboring rows of the panel sections such as the rows  751  and  752 . Given the presence of these gaps between the top panel surfaces  763  of neighboring rows of the panel sections  750  such as the panel sections of the rows  751  and  752 , in the present embodiment additional cover structures (or gap fillers)  767  are provided subsequent to the implementation of the panel sections onto the wire tendons  230 , with one of the additional cover structures  767  particularly being shown in  FIGS. 7A and 7B . The additional cover structures  767  serve to fill in the gaps between the top panel surfaces  763  of the panel sections  750  of neighboring rows of the panel sections (again, such as the rows  751  and  752 ) and to cover over the pairs of wire tendons  230  therebetween (e.g., the pair of wire tendons  302 ) along generally the entire lengths of those wire tendons except for locations at which suspension chains are coupled to the wire tendons by way of suspender structures discussed further below. 
     As illustrated particularly in  FIGS. 7A and 7B , the additional cover structures  767  have widths that are greater than the gaps between the rows of panel sections such that outer edges  899  of the additional cover structures actually extend over edge portions of the panel sections ( FIG. 7B  shows the outer edges  899  in phantom). Additionally, as illustrated in  FIGS. 7A, 7B , as well as  FIGS. 17A, 17B, 17C, 17D, 18, 19, and 20  discussed further below, the additional cover structures  767  in the present embodiment are coupled tightly to the wire tendons  230  by way of additional components. 
     More particularly, in the present embodiment, the additional cover structures  767  includes a pair of bolt holes  950  by which the additional cover structures  767  can be bolted to a pair of tendon retainer structures  769 .  FIG. 18  shows a perspective view of one of the additional cover structures  767  and particularly shows the bolt holes  950 .  FIGS. 17A, 17B, 17C, and 17D , respectively, show a perspective side view, top plan view, side elevation view, and end elevation view of an example one of the tendon retainer structures  769 . As shown, the tendon retainer structure  769  includes a main outer shell  952  having a roof  954  and first and second side walls  956  and  957  respectively extending downwards from each of two sides of the roof, respectively. Also, the tendon retainer structure  769  includes a flat internal compression structure  958  that includes two ear extensions  960  that respectively fit into two complementary slots  962  formed near the bottom edges of each of the two side walls  956 ,  957 . Although generally complementary, the complementary slots  962  are slightly larger than the ear extensions  960 , particularly in a vertical direction. Consequently, when the flat internal compression structure  958  is positioned within an internal channel  964  between the side walls  956  and  957  of the main outer shell  952  such that the ear extensions  960  extend within the complementary slots  962 , the flat internal compression structure  958  can move vertically upward and downward relative to the main outer shell  952 . 
     In addition to the above-mentioned features, the first side wall  956  of the main outer shell  952  has first and second wire receiving indentations  966  and  967 , respectively, and the second side wall  957  has third and fourth wire receiving indentations  968  and  969 , respectively. As shown, all of the wire receiving indentations  966 ,  967 ,  968 , and  969  are generally located at a vertical level that is substantially the same, but slightly higher, than the complementary slots. Also, the first and second wire receiving indentations  966  and  967  are located respectively at generally opposite ends of the first side wall  956 , and the third and fourth wire receiving indentations  968  and  969  are located respectively at generally opposite ends of the second side wall  957 . As will be discussed further below, the first and third indentations  966  and  968 , respectively, share in common a first shape that includes an elongated indented portion  970 , and are respectively located at respectively opposite ends of the first and second side walls  956  and  957 , respectively. By comparison, the second and fourth indentations  967  and  969 , respectively, share in common a second shape that lacks the elongated indented portion, and are located at respectively opposite ends of the first and second side walls  956  and  957 , respectively. Additionally, it will be appreciated that the roof  954  of the main outer shell  952  includes an orifice  971  and the flat internal compression structure  958  also includes snap-in cage nut having a threaded internal orifice  972  that is generally aligned with the orifice  971  when the ear extensions  960  are within the complementary slots  962 . 
     Turning to  FIG. 20 , an exploded perspective, partly cutaway view is provided of the tendon retainer structure  769  in relation to each of the additional cover structure  767  of  FIG. 18 , an additional retainer bracket  980 , a retaining bolt  982 , and the pair of wire tendons  302 .  FIG. 20  particularly indicates how the tendon retainer structure  769  can be positioned onto the pair of wire tendons  302  and, once so positioned, can grip the wire tendons. More particularly, it can be appreciated that the tendon retainer structure  769  first can be positioned onto the wire tendons  230  by first positioning the tendon retainer structure generally in between the wire tendons so that the channel  964  is generally aligned with the lengths of the wire tendons, and then rotating the tendon retainer structure in a direction indicated by an arrow  984  so that the wire tendons are fit into the first, second, third, and fourth wire receiving indentations  966 ,  967 ,  968 , and  969 . It will be appreciated that this process of rotating the tendon retainer structure  769  into position in this regard is facilitated by the elongated indented portions  970  of the first and third wire receiving indentations  966  and  968 . 
     Additionally, with the tendon retainer structure  769  positioned onto the wire tendons  302 , the additional cover structure  767  is positioned so that one of the bolt holes  950  is over the orifice  971  and particularly aligned with the threaded internal orifice  972 . Further, the retainer bracket  980 , which in the present embodiment is an L-shaped bracket having two orifices  985  that are located respectively on each of a horizontal wall portion  986  and a vertical wall portion  988  of the bracket, is aligned so that the orifice  985  on the horizontal wall portion  986  is also aligned with the threaded internal orifice  972 . With all of these components so aligned and positioned so that the additional cover structure  767  is atop the roof  954  and the horizontal wall portion  986  is atop the additional cover structure, then the bolt  982  can be inserted through the orifice  985 , bolt hole  950 , orifice  971  and into the threaded internal orifice  972 . Rotational tightening of the bolt  982  then has the effect of rotating the cage nut within which the threaded internal orifice  972  is formed, thus causing the flat internal compression structure  958  to move upwards relative to the shell  952  so as to grip the wire tendons  302  with flat internal compression structure and the upper surfaces of the indentations  966 ,  967 ,  968 , and  969 . As this occurs, the retainer bracket  980  is held against the tendon retainer structure  769  with the additional cover structure  767  sandwiched in between, such that ultimately all of the retainer bracket, additional cover structure, and the tendon retainer structure are fixedly coupled to the wire tendons  302  in a robust manner. In view of the securing function of tendon retainer structure  769  relative to the panels, tendon retainer structure  769  can in some embodiments be referred to as a deck retainer clamp. 
       FIGS. 17E and 17F  illustrate an alternative embodiment of tendon retainer structure  1200 . In some embodiments of suspended subsystem  120 , tendons  230  are configured lower in relation to panel sections  750 . In such embodiments, a tendon retainer structure  1200  as illustrated in  FIGS. 17E and 17F  can be used. Tendon retainer structure  1200  is essentially identical to retainer structure  769  except for side walls  956 ′,  957 ′ which are elongated to account for tendons  230  at a lower position, and internal compression structure  958 ′ which is contoured instead of flat. 
     Also, in some embodiments, the tendon retainer structure  1200  includes an internal compression structure  958 ′ which is elongated, as shown in  FIGS. 17E and 17F . Importantly, it is not necessary for an internal compression structure to be contoured (as in  958 ′) in order to be elongated. The tendon retainer structure  769  of  FIG. 20 , for example, also contains an elongated internal compression structure  958 . Referring back to  FIG. 11P or 11Q , it is more easily seen that the elongated internal compression structures  958 / 958 ′ are designed to project into the tubular struts forming the framework of the panel structures. 
     With respect to the retainer bracket  980  in particular, it should be appreciated such retainer brackets are only optional with respect to the implementation of any given one of the tendon retainer structures  769  and additional cover structures  767 . The retainer brackets  980  can particularly be provided in areas where it is desired to fixedly mount other structures in relation to (or as part of) the wire tendons  230  and/or the panel structures  750 , for example, to mount guard rails. That said, it should be evident from  FIGS. 7A and 7B  that, in the embodiment shown there, no retainer brackets are present. Rather, as illustrated by  FIG. 7B , only the additional cover structure  767  is affixed to the tendon retainer structure  769 , which is particularly shown in  FIG. 7B . Nevertheless, it should be particularly evident from  FIGS. 7A and 7B  that, thanks to the fixed coupling of the additional cover structure  767  to the tendon retainer structure  769  and the fixed coupling of both of those structures to the wire tendons  302  by way of the bolt  982 , the additional cover structure  767  because of its edges  899  overlapping the panel sections can fill in the gap between the neighboring rows of the panel sections and also act as a redundant means of securing panel sections in relation to the wire tendons  302 . 
     Referring now to  FIGS. 18B-18H , additional cover structure can have alternative configurations which allow additional cover structure to be used without tendon retainer structure  769 . In such instances, additional cover structures function as gap fillers to cover the gaps between decking panels. 
     As illustrated in  FIGS. 18B, 18C and 18D , alternative embodiments of additional cover structure  1300  include a first end  1302  with a protuberance  1303  and a second end  1315  with a receiving aperture  1316  and tendon-engaging side wall  1317 . The protuberance  1303  is designed to engage the receiving aperture  1316  of a subsequent cover section  1300 . For example, as illustrated in  FIGS. 18B, 18C and 18D , and perhaps best in  FIG. 18C  which is a side view of the cover section  1300  of  FIG. 18B , Z-shaped protuberance  1303  includes horizontal extension portion  1305  which transitions to vertical side wall  1306  at a distance away from the main body portion of additional cover structure  1300 . Vertical side wall  1306  then transitions to engaging protuberance  1307  which extends horizontally from vertical side wall  1306 . 
     In the exemplary embodiments shown in  FIGS. 18B, 18C and 18D , Z-shaped protuberance  1303  has a substantially Z-like configuration with vertical side wall  1306  angled outward away from additional cover structure  1300 , and horizontal extension portion  1305  and engaging protuberance  1307  are substantially parallel with each other. In further exemplary embodiments, Z-shaped protuberance  1303  can include a vertical side wall  1306  with a different angle, and horizontal extension portion  1305  and engaging protuberance  1307  can be other than substantially parallel. 
     When assembled as illustrated in  FIG. 18D , a first additional cover structure  1300  is held approximately perpendicular to an already installed additional cover structure  1301  such that the Z-shaped protuberance  1303  of the first additional cover structure  1300  is over the receiving aperture  1316  of the installed additional cover structure  1301 . As the engaging protuberance  1307  of the first additional cover structure enters the receiving aperture  1316  of the installed additional cover structure  1301 , the first additional cover structure  1300  is rotated to a more horizontal position such that the engaging protuberance  1307  extends under the installed additional cover structure  1301  and vertical side wall  1306  enters the receiving aperture  1316  of installed additional cover structure  1301 . 
     As the first additional cover structure  1300  continues to rotate to a final horizontal position, wire tendons  302  contact, directly or indirectly, the tendon-engaging side wall  1317 . In the exemplary embodiments shown in  FIGS. 18B-18D , tendon-engaging side walls include two legs  1318 , each including a tendon indentation  1312  and a corresponding angled side surface  1311 , separated by cut-away  1319 . As first additional cover structure  1300  continues to a horizontal position, wire tendons  302  will first contact angled side surfaces  1311 . The pressure exerted on angled side surfaces  1311  causes legs  1318  to flex towards each other, allowing tendons  302  to continue sliding up angled side surfaces  1311  as the first additional cover structure  1300  continues to its final horizontal position. 
     Once first additional cover structure  1300  reaches its final position, Z-shaped protuberance  1303  fully engages receiving aperture  1316  and tendons  302  snap into position at tendon indentations  1312 . Legs  1318  are no longer flexed, and upward movement of the additional cover structure  1300  relative to the tendons  302  is prevented by the engagement of tendons  302  in tendon indentations  1312 . 
     It is to be appreciated that alternate configurations of protuberance  1303  can require different positioning and rotating to engage protuberance  1303  with receiving aperture  1316 . 
       FIGS. 18E and 18F  illustrate a second alternative embodiment of additional cover structure  1320  which includes a first end  1322  with a tendon-engaging side wall  1325  and a second end  1324  with a tendon-engaging side wall  1325 . 
       FIGS. 18G and 18H  illustrate a third alternative embodiment of additional cover structure  1330  having tendon-engaging side wall  1335  and receiving aperture  1336  at a first end  1334  and a tapered body  1331  resulting in a second end  1332  having a smaller width than first end  1334 . Second end  1332  is inserted directly into receiving aperture  1336  to secure additional cover structures  1330  together, with tendon-engaging side wall  1335  engaging tendons  302  as described above. 
     It will be appreciated that there is some overlap of additional cover structures when installed. It will further be appreciated that tendon retainer structure  769  is not necessary when using alternative additional cover structures  1300 ,  1320 ,  1330  because additional cover structures  1300 ,  1320 ,  1330  engage tendons  302  directly or indirectly. However, additional cover structures  1300 ,  1320 ,  1330  can, in some instances, still be used with tendon retainer structures  769 , such as, for example, when installing a guard rail at an interior point, i.e., a point not along the exterior perimeter of a suspended subsystem  120 . 
     As illustrated in each of  FIGS. 18B-18H , each additional cover structure  1300 ,  1320 ,  1330  includes a central aperture, or bolt hole  950 ′. Central aperture  950 ′ can be used to secure additional structures to additional cover structures  1300 ,  1320 ,  1330 , including but not limited to containment brackets, rail posts, uplift posts and other structures known and used in the art. It will further be appreciated that the additional cover structures of  FIGS. 18B-18H  grip tendons by simply pushing the structures downward onto the tendons and allowing the tendons to engage the respective tendon-engaging portions. In other words, no moving components are used (i.e., no opening and/or closing of tendon-engaging structures) for quick and easy installation of additional cover structures/gap fillers. 
       FIGS. 18I-18M  illustrate yet a further embodiment of an additional cover structure  1300 ′. In the exemplary embodiment shown in  FIGS. 18I-18M , additional cover structure  1300 ′ has a first end  1302 ′ including an engaging contour  1303 ′, which in  FIG. 18I  is shown as a Z-bend, and a first clip slot  1310 ′. As shown in  FIG. 18I , Z-shaped protuberance  1303 ′ is substantially similar to protuberance  1303  in structure and function, as described above in reference to  FIGS. 18B-18D . Additional cover structure  1300 ′ also has a second end  1315 ′ including a plurality of Z-bend slots  1316 ′ and a second clip slot  1310 ′. In the exemplary embodiment shown, clip slots  1310 ′ include a plurality of raised bumps  1304 ′ arranged in pairs on either side of clip slots  1310 ′. 
       FIG. 18J  shows a clip  1111 ′ that is used with additional cover structure  1300 ′. Clip  1111 ′ is an oblong component having a grasping portion  1112 ′, neck  1113 ′, and clip body  1114 ′. As explained in further detail with respect to  FIGS. 18  K and  18 L, grasping portion  1112 ′ has a length and width approximately equal to, though just smaller than, the dimensions of clip slot  1310 ′ so that it passes through clip slot  1310 ′. Similarly, neck  1113 ′ has a length and width such that it can rotate within clip slot  1310 ′. Clip body  1114 ′ includes two tendon-engaging portions  1115 ′, each being flexible to slide over and receive a tendon. Tendon-engaging portions each comprise two legs  1116 ′ with lower angled surfaces  1117 ′ and together the legs  1116 ′ form tendon-receiving apertures  1118 ′ and flex gaps  1119 ′. It will be appreciated that, like additional cover structures of  FIGS. 18B-18H , clip  1111 ′ engages tendons without moveable components (i.e., no opening and/or closing of tendon-engaging structures). 
       FIGS. 18K and 18L  show how clip  1111 ′ engages additional cover structure  1300 ′ prior to assembly with a platform system. As illustrated in  FIG. 18K , clip  1111 ′ is first inserted into clip slot  1310 ′ from the bottom such that grasping portion  1112 ′ is parallel with clip slot  1310 ′. Once clip  1111 ′ projects through clip slot  1310 ′ such that neck  1113 ′ is within the clip slot  1310 ′, clip  1111 ′ is rotated such that grasping portion  1112 ′ is perpendicular with clip slot  1310 ′. To that end, it is appreciated that neck portion  1113 ′ has a diameter just smaller than the width of clip slot  1310 ′ to permit free rotation of clip  1111 ′ within clip slot  1310 ′. As a result, grasping portion  1112 ′ is disposed between pairs of bumps  1304 ′. Bumps  1304 ′ prevent rotational movement of clip  1111 ′. It should be appreciated that other structures and devices, as well as different configurations of raised bumps, can be used to prevent rotation of clip  1111 ′ while engaging tendons. 
       FIGS. 18M and 18N  illustrate clip  1111 ′ engaged with additional cover structure  1300   a ′ to engage tendons. As illustrated in  FIG. 18M , additional cover structure  1300   b ′ is installed with clip  1111 ′ engaging tendons. Additional cover structure  1300   a ′ is installed by first engaging the Z-bend  1303 ′ with corresponding Z-bend slots  1316 ′ of additional cover structure  1300   b ′. It is appreciated that clip slots  1310 ′ on the respective additional cover structures  1300   a ′ and  1300   b ′ do not overlap. Rather, each clip slot  1310 ′ of additional cover structures  1300   a ′ and  1300   b ′ can be used to secure additional cover structures  1300   a ′ and  1300   b ′ to the tendons as required. 
     As additional cover structure  1300   a ′ is pivoted downward (as described generically with reference to  FIGS. 18B-18D ), tendon-engaging portions  1115 ′ of clip  1111 ′ are aligned over tendons. Tendons first engage lower angled surfaces  1117 ′, forcing legs  1116 ′ of each tendon-engaging portion  1115 ′ to separate slightly. Flex gaps  1119 ′ allow the legs  1116 ′ to separate in this manner without requiring a worker or other individual to physically manipulate (that is open or close) tendon engaging portion  1115 ′ or legs  1116 ′. With further pushing, legs  1116 ′ separate enough to permit tendons to enter tendon-receiving apertures  1118 ′, as illustrated in  FIG. 18N . 
     It is appreciated that additional cover structures  1300 ′ do not directly contact or rest on tendons. Rather, as illustrated in the figures, clips  1111 ′ act as an indirect connection between tendons and additional cover structures  1300 ′. As illustrated with reference to, for example,  FIG. 18H , it is further understood that additional cover structures  1300 ′ overlap panel sections  765 , thereby transferring at least part of any load placed on additional cover structures  1300 ′ to panel section  765  and not directly to tendons through clips  1111 ′. 
     Referring still to  FIGS. 7, 7A, and 7B , and also referring now to  FIG. 12 , in the present embodiment the further implemented suspended subsystem  720  also includes, in addition to the pairs of wire tendons  230  and the panel structures  750  supported thereon (plus the cover sections such as the cover section  767  positioned in between the rows of panel sections), suspension chains  790  that are coupled between the underside of the deck  222  of the suspension bridge  100  and the pairs of wire tendons  230  at various locations along the lengths of the wire tendons. The suspension chains  790  can be periodically spaced along the lengths of each of the pairs of the wire tendons  230 , and the number of such suspension chains can vary depending upon the circumstances or embodiment.  FIG. 12  shows particularly two of the suspension chains that have been positioned along at least the fourth pair of wire tendons  304 , upon which are supported the third and fourth rows of the panel sections  753  and  754  that are fully complete in that each of those rows (unlike the other rows  751 ,  755 ,  756 ,  757 , and  758 ) include panel sections  750  that have been implemented along the entire length of the fourth pair of wire tendons  304 . 
     It should be appreciated that, although not clearly apparent from  FIG. 12 , one or more of the suspension chains  790  are provided in relation to each of the pairs of wire tendons  230  (e.g., in relation to each of the wire tendon pairs  301 ,  302 ,  303 ,  304 ,  305 ,  306 ,  307 ,  308 , and  309  in the example of  FIG. 7 ). Each of the suspension chains  790  along a particular pair of the wire tendons  230  is installed typically only when a sufficient number of the panel sections  750  have been installed onto that pair of wire tendons so as to allow work personnel to walk out to the respective location at which the respective suspension chain is to be attached. Although the number of the suspension chains  790  along each of the pairs of wire tendons  230  can be the same and the relative spacing of the suspension chains  790  along each of the pairs of wire tendons are identical in the present embodiment, this need not be the case in all embodiments. For example, in another alternate embodiment, it is possible that suspension chains  790  will be provided with a first spacing frequency along the length of one pair of the wire tendons and provided with a different spacing frequency along the length of another pair of the wire tendons. 
     Further as shown, in order to couple the suspension chains  790  to the pairs of wire tendons  230 , in the present embodiment, suspender structures  800  are employed, one of which is shown in each of  FIGS. 7A and 7B  and others of which are shown in  FIG. 12 . Referring further to  FIGS. 13A and 13B  in this regard, an exploded perspective side view of one of the suspender structures  800  and a top plan view of the suspender structures  800  are shown, respectively, to illustrate particular features of the suspender structures  800 . As shown, the suspender structures  800  includes a top planar (or substantially planar) surface  802  that extends between side edges  804  and further includes downwardly extending bracket extensions  806  positioned at each of first and second ends  808  of the suspender structure  800 . Similar to the wire tendon support extensions  770  of the panel sections  750 , the bracket extensions  806  each include a respective pair of indentations  810  that are intended to cover over and receive wire tendons of a given pair of the wire tendons  230  so that the structure  800  is positioned into place relative to the pair of wire tendons, for example as shown in  FIG. 7B . Additionally, the top planar surface  802  has a width between the side edges  804  that is substantially equal to that of the additional cover structures  767  that, as discussed above, can be provided to extend between neighboring panel sections  750  of the rows of panel sections. Thus, the top planar surfaces  802  of the suspender structures  800  can serve a similar purpose of filling in the gaps between neighboring panel sections of neighboring rows of panel sections, particularly at the locations along the pairs of wire tendons  230  at which the suspender structures are positioned. 
     Further as shown, the suspender structure  800  includes a main body  801  having a top handle portion  812  that includes a planar portion  814  that overlays the top planar surface  802  along much of that surface and further includes two upwardly extending handle portions  816  that extend upward from the planar portion  814  diagonally upwards, that is, both upwards away from the top planar surface  802  and generally outwards toward the respective side edges  804  of the suspender structure  800 . Each of the handle portions  816  includes a respective slot  818  by which work personnel implementing the suspender structure  800  can grasp the suspender structure. Further as shown, the top planar surface  802  as well as the planar portion  814  include three additional holes or orifices, namely, first and second end orifices  820  that are circular and an intermediate orifice  822  that is oblong. The end orifices  820  are respectively positioned proximate opposite ends of the intermediate orifice  822 , in between those respective opposite ends of the intermediate orifice  822  and outer end tips  824  of the planar portion  814 . Further, additional orifices  826  that are also circular and of smaller diameter than the orifices  820  are positioned proximate the bracket extensions  806  of the top planar surface  802 . Each of the additional orifices  826  is positioned generally to the side of a respective one of the outer end tips  824  of the planar portion  814 . 
     The intermediate orifice  822  as shown includes a central region  821 , end slot regions  823 , and intermediate transverse slot regions  825  that allow the intermediate orifice to serve as an attachment feature by which one (or potentially more than one) of the suspension chains  790  can be attached to the suspender structure  800 . Although not shown in detail in  FIGS. 13A and 13B , it should be understood that one of the suspension chains  790  can be attached by inserting a free end of the suspension chain through the central region  821  of the intermediate orifice  822  and then sliding the suspension chain over and into one of the end slot regions  823 . Once the suspension chain  790  is placed within one of the end slot regions  823 , a suspension chain retainer pin (not shown) is placed in that one of the transverse slot regions  825  that is adjacent that end slot region so that the suspension chain  790  is kept retained in that end slot region. The suspension chain  790  and intermediate orifice  822  (and particularly the end slot regions  823 ) are sized and configured so that, upon proper placement of the retainer pin within the appropriate transverse slot region, the suspension chain is effectively locked to the main body  801  of the suspender structure  800  and is unable to slip, vertically or horizontally, from its position in the end slot region  823 . This locking system effectively fixes the suspender structure  800  to the suspension chain  790 . Additionally, in some embodiments, an additional “zip tie” or other tag type structure can be placed between a hole in the retainer pin and an adjacent portion of the suspension chain  790  to provide a visual aid to the installer to ensure that the retainer pin has been installed. 
     In contrast to the intermediate orifice  822 , the orifices  820  and  826  allow for assembly of first and second grasping portions (or clasp portions)  830  to the main body  801  of the suspender structure  800  in a manner that allows the suspender structure to grasp the wire tendons of a pair of the wire tendons  230  and lock the suspender structure in relation to those wire tendons such that tension force provided by the suspension chain  790  can be applied to the wire tendons and hold those wire tendons in place relative to the deck  222 . More particularly as shown, each of the grasping portions  830  includes a central post  832  that extends upward from a central location  836  along a horizontally extending portion  834  that extends outward in opposite directions from that central location. Further as illustrated, each of the grasping portions  830  also includes an additional post  838  that is offset radially from the central location  836  and central post  832  and that has a smaller diameter than the central post. More particularly as shown, the location of the additional post  838  is still relatively close to the central post  832  by comparison with how close ends  840  of the horizontally extending portion  834  are located relative to the central post  832 , but also is offset from a central axis  842  (that is, shifted to the side of that central axis  842 ) extending between the ends  840 . 
     Implementation of the suspender structure  800  in relation to a pair of the wire tendons  230  proceeds by first inserting the respective central posts  832  of the two respective grasping portions  830  into the respective end orifices  820  of the main body  801  from underneath the main body, with both of the grasping portions rotated so as to be axially aligned with the central axis  842 , such that the grasping portions are in starting orientations  843  as shown in  FIG. 13B . Once the central posts  832  are inserted through the end orifices  820 , the central posts  832  are coupled to the main body  801  by way of nuts  844  so as to retain the grasping portions  830  in relation to the main body  801 . With the grasping portions  830  oriented in this manner, it is then possible to install the suspender structure  800  (to which a suspension chain  790  can already have been coupled as discussed above) onto the pair of wire tendons  230 , so that the wire tendons  230  proceed into the indentations  810 . Alignment of both of the grasping portions  830  in the starting orientations  843  aligned with the central axis  842  allows for the grasping portions to be slipped initially in between the wire tendons of the given pair of wire tendons. 
     Once the suspender structure  800  is in position relative to the pair of wire tendons  230  as discussed above, then the grasping portions  830  are further rotated ninety degrees (90°), in the present example in a clockwise manner as indicated by arrows  846 , until the additional posts  838  (and particularly tips/heads thereof) become aligned with the additional orifices  826 . This rotation can be accomplished by way of torque bolts. Once this has occurred, the nuts  844  can be further tightened so as to cause the grasping portions  830  to move upward towards the main body  801  and grasp fixedly the pair of wire tendons  230  extending between the grasping portions and the main body. Indentations  848  formed along upper side edges of the horizontally extending section  840  of each of the grasping portions  830  further enables the wire tendons to be grasped in this manner. In view of the installation procedure of suspender structure  800 , and its functions of grasping tendons and securing a suspension chain(s), suspender structure  800  can, in some embodiments, be referred to as a suspender clamp. 
     As will be appreciated, the suspension chains  790  by virtue of the suspender structures  800  serve to provide extra support to the further implemented suspended subsystem  720  at locations in between the portions  132  and  134  of the support subsystem  130  (e.g., the two portions located respectively at the two towers  140 ) to which the ends of the further implemented suspended subsystem  720  and wire tendons  230  thereof are coupled. Such extra support helps to keep the support subsystem  130  flat (or substantially flat) along its length, and to eliminate or reduce undulation occurring along its length. Additionally it should be appreciated, particularly with reference to  FIG. 7B , that the suspender structures  800  with the grasping portions  830  (and horizontally extending portions  834  thereof) also serve to help retain panel sections  750 . As is evident from  FIG. 7B , when implemented in relation to one of the suspender structures  800 , the panel sections  750  extend beneath the side edges  804  of the top planar surface  802  of the suspender structure. Also as shown in  FIG. 7B , in addition to the panel sections  750  extending beneath the side edges  804  of the suspender structure  800 , the grasping portions  830  (and horizontally extending portions  834  thereof) of the suspender structure  800  when rotated into position also are positioned so that the panel sections  750  (and particularly the end struts  764  thereof) are situated in between the ends  840  of the horizontally extending portions  834  and the side edges  804 . Thus, the horizontally extending portions  834  further serve to assist with retaining in place the panel sections  750 . 
       FIGS. 14A and 14B  illustrate an alternative embodiment of suspender structure  1400 . As described in further detail below, it is to be understood that the different modifications of alternative suspender structure  1400  can be used independently with suspender structure  800  of  FIGS. 13A and 13B . For example, in some embodiments of suspended subsystem  880 , tendons  230  are configured lower in relation to panel sections  750 . In such embodiments, a suspender structure  1400  as illustrated in  FIG. 14A  having elongated bracket extensions  806 ′ to account for tendons  230  at a lower position can be used. Additional changes to various surfaces (i.e.,  834 ′,  840 ′) can also be required to account for lowered tendons. 
       FIG. 14A  also shows alternative structures for tightening grasping portions  830 ′ to engage tendons  230 . In the embodiment shown, instead of using central posts  832  that project upward from grasping portions  830  and secure to main body  801  with nuts  844 , suspension structure  1400  uses bolts  832 ′ that extend downward through main body  801 ′. Nuts  844 ′ are secured to bolts  832 ′ below grasping portions  830 ′. 
     As shown in  FIGS. 14A and 14B , bolts  832 ′ contain an unthreaded portion  832   a ′, which allows grasping portions  830 ′ to slide easily on bolts  832 ′ as the nuts  844 ′ are rotated around threaded portion  832   b ′ of bolts  832 ′. As nuts  844 ′ are tightened onto bolts  832 ′, grasping portions  830 ′ are forced upward to secure tendons  230 . As nuts  844 ′ are loosened from bolts  832 ′, grasping portions  830 ′ are released downward to release tendons  230 . Once nuts  844 ′ are loosened completely, nuts  844 ′ are disposed about a second unthreaded portion  832   c ′ of bolt  832 ′. 
     Bolts  832 ′ also include lower washer  837   b ′, connected to bolts  832 ′ by roll pin  837   a ′, which prevents nut  844 ′ from disengaging bolt  832 ′ completely. In the embodiment shown, spring  839 ′ is disposed between washer  837   b ′ and nut  844 ′. Spring  839 ′ keeps nut  844 ′ pushed up against threaded portion  832   b ′ of bolt  832 ′, making it easier to re-engage threaded portion  832   b ′. Spring  839 ′ can, however, be omitted in other exemplary embodiments, and lower washer  837   b ′ can be secured to bolts  832 ′ using additional or alternative structures. 
     It should be appreciated that grasping portions  830 ′ are not removable from main body  801 ′ of suspender structure  1400  in the embodiment shown in  FIGS. 14A and 14B . This allows for easier assembly of the work platform assembly and prevents lost parts. The design of suspender structure  1400  also allows for attachment of the suspender structure  1400  to tendons  230  from above the work platform assembly. 
     Referring now to  FIGS. 21-25 , in some embodiments of the work platform system shown in  FIGS. 1, 3, 7 , etc., additional components, such as toe boards and railings, can be incorporated with the work platform system and panel sections  750 . For example,  FIG. 21  illustrates a panel section  750  with an exemplary rail post  2000  and toe board frame  2500  with toe board  2700  ready for installation of toe board frame  2500 .  FIG. 22  illustrates the toe board frame  2500  in more detail. 
       FIG. 21  illustrates an exemplary rail post  2000 , which in the embodiment shown, is a squared hollow post containing two rail system securing structures  2002 , which in the embodiment shown are looped structures. In further embodiments, rail post  2000  can have any shape, and rail system securing structures  2002  can be any structure designed to secure a rail system. For example, chains, rope or other material can be strung through looped structures  2002  to create a rail system. 
       FIG. 21  shows toe board  2700  ready to install on toe board frame  2500 . Toe board  2700  is contoured to correspond to the shape of toe board frame  2500  and has a securing aperture  2701  which corresponds to the aperture  2406  of rail post mount  2400 . Bolt  2702  is used to secure toe board  2700  to toe board frame  2500  by engaging apertures  2701  and  2406 . However, in further exemplary embodiments, it is understood that different securing mechanisms and structures can be used. 
     As illustrated in  FIGS. 21 and 22A , toe board frame  2500  is a bent frame  2502  made of squared tubular material with two panel engaging extensions  2505  configured to insert into struts  760  of panel section  750  (see  FIGS. 8, 9, and 10 ) and rail post supporting member  2520 . Central brace  2510  includes securing flange  2515  for attaching a toe board and/or rail  2000 , and securing flange  2515  includes a cage nut (not shown) installed on the bottom of flange  2515 . Toe board frame  2500  also includes apertures  2504 , which corresponds to aperture  2503  on tendon extension  770  of panel section  750 . Additional securing components (i.e., zip ties, bolts, etc.) can be optionally used to further secure toe board frame  2500  to panel section  750 . 
       FIG. 22B  shows an alternate embodiment of a toe board frame  2500 ′. In the embodiment shown in  FIG. 22B , toe board frame  2500 ′ includes two buttons  2580  in place of apertures  2504 . Buttons  2580  are made from bent portions of flexible metal  2584  having a single protuberance  2582  on each end. Buttons  2580  are inserted within horizontal extensions  2505  such that the protuberances  2582  extend out of holes in horizontal extensions  2505 . Buttons  2580  engage apertures  2503  on tendon extensions  770  of panel section  750 . 
     While in the embodiment described above, buttons  2580  are specifically described as a bent portion of flexible metal containing a protuberance at each end, it is to be understood that different materials and structures can be used to provide movable protuberances which extend outward from the horizontal extensions  2505  of toe board frame  2500 ′. For example, other structures such as spring loaded pins, ball locks, friction fit components, and other structures and devices known in the art. 
       FIG. 23  illustrates an exemplary rail post mount  2400  for use with toe board frame  2500 . Rail post mount  2400  includes a front plate  2402 , first side plate  2412  and second side plate  2422 . Side plates  2412 ,  2422  are separated by a distance to form a rear channel  2450 , having interior dimension corresponding to the exterior dimensions of rail post  2000 . To secure rail post  2000  to rail post mount  2400 , side plates  2412 ,  2422  include a plurality of apertures and/or contours which correspond to apertures/contours on rail post  2000 . Rail post  2000  can then be secured in channel  2450  using bolts, ties, or any other structure or device known in the art. 
     In some embodiments, such as illustrated in  FIG. 24 , rail post  2000  includes one or more spring-loaded pins  2005 , and channel  2450  includes a plurality of apertures corresponding to different placements of rail post  2000  within channel  2450 . Using a spring-loaded pin allows rail post  2000  to be easily moved up or down within channel  2450  by simply depressing the pin to disengage the pin from a corresponding aperture and sliding the rail post  2000  up or down until the pin re-engages an aperture. In further embodiments, rail post  2000  can secure to rail post mount  2400  using one or more carriage bolts  2008  either in addition to a spring-loaded pin  2005  or other securing mechanism, or as a sole securing mechanism. 
     Front plate  2402  includes bottom portion  2403  with apertures  2406  and vertical surface  2407 . Bottom portion  2403  transitions into vertical plate  2404 , which then transitions into hook  2405 . Vertical plate  2404  forms a third wall of channel  2450  so that channel  2450  becomes closed on three sides, with the top, bottom and one side of the channel being open. 
     As illustrated in  FIG. 21 , when rail post mount  2400  is secured on toe board frame  2500 , vertical surface  2407  contacts central brace  2510  such that apertures  2406  align with apertures  2516  of securing flange  2515  and hook  2405  secures over top member  2502  of toe board frame  2500 . Rail post mount  2400  and toe board frame  2500  is then further secured at apertures  2406 ,  2516  using bolts, ties or any other structure or device known in the art. In some exemplary embodiments, toe board frame  2500  can include a cage nut on central brace  2510  below flange  2515 . When rail post mount  2400  is secured to toe board frame  2500 , vertical surface  2407  contacts central brace  2510  below flange  2515  and above the cage nut. To secure rail post mount  2400  to toe board frame  2500 , a nut passes first through an aperture  2516  of flange  2515 , then through an aperture  2406  on bottom portion  2403  of rail post mount  2400 , and ultimately engages the cage nut. 
     In further embodiments, bottom portion  2403  includes an aperture  2406  and a spring-loaded pin  2409 . When rail post mount  2400  is connected to toe board frame  2500 , spring-loaded pin  2409  is depressed while vertical surface  2407  is slide under flange  2515 . Once spring-loaded pin  2409  is aligned with the corresponding aperture  2516  on flange  2515 , spring-loaded pin  2409  engages the aperture  2516  and helps to secure rail post mount  2400  to and align rail post mount  2400  with toe board frame  2500 . 
       FIG. 25  illustrates an exemplary work platform system with panel sections  750  installed with additional cover structures  1300  in place. Toe boards  2600  are secured to toe board frames  2500 . In the exemplary embodiment shown, rail posts  2000  are also included at every fourth toe board  2600 . However, in further embodiments, more or fewer rail posts  2000  can be used, and, as described above, rail posts  2000  can be positioned at a point interior from toe boards  2600 . 
       FIG. 25  also shows suspender structures  800  located at approximately every sixth toe board  2600 . However, it should be appreciated that more or fewer suspender structures  800  can be used, and suspender structures  800  can be positioned at any frequency along toe boards. As described in more detail with respect to  FIGS. 13A  and  13 B, suspender structures  800  have a width such that, when installed between panel sections  750 , suspender structures  800  act to fill the gap between panel sections  750  and are stabilized in location by side edges  804  of suspender structures  800  resting on panel sections  750 . When used at an exterior panel section  750 , there is only a single panel section  750  to stabilize suspender structures  800 . In place of the second panel section  750 , suspender structure uses central brace  2510  of toe board frame  2500 . 
       FIGS. 26-29  show alternative additional components, such as toe boards and railing systems. For example,  FIG. 26  illustrates an alternative toe board frame  2500 ″ with securing flange  2515 ″ and rail post mount  2400 ″. As shown, toe board frame  2500 ″ is a bent frame  2502 ″ made of squared tubular material with two panel engaging extensions  2505 ″ configured to insert into struts  760 / 760 ′ of panel sections  750  and rail post support member  2520 ″. Unlike toe board frames  2500  and  2500 ′, toe board frame  2500 ″ does not contain an upward vertical bend. Central brace  2510 ″ includes securing flange  2515 ″ with aperture  2406 ″ for securing a toe board and rail post mount  2400 ″ for securing a rail post. Toe board frame also includes apertures  2504 ″ and/or buttons  2580 ″ which correspond to apertures  2503 ″ on panel sections  750 , as described with reference to  FIGS. 22A and 22B , above. 
     As shown in  FIG. 26 , rail post mount  2400 ″ is a rounded tubular structure with an inner diameter slightly larger than the outer diameter of rail post  2000 ″ ( FIG. 28A ). Rail post mount  2400 ″ contains apertures  2410 ″ which correspond to apertures and/or buttons on rail post  2000 ″ to secure rail post  2000 ″ in rail post mount  2400 ″. It is to be appreciated that there is not bottom surface to rail post mount  2400 ″ to allow adjustable vertical positioning of a rail post  2000 ″. 
     As further shown in  FIG. 29 , securing flange  2515 ″ also includes rail system securing apertures  2512 ″ for use with flexible rail systems, such as chains. 
       FIG. 27  illustrates an exemplary toe board  2702 ″ for use with toe board frame  2500 ″. Where toe board frame  2700  is specifically contoured to correspond to toe board frames  2500  and  2500 ′, toe board frame  2700 ″ is similarly contoured to correspond to toe board frame  2500 ″. As shown, toe board  2700 ″ also includes aperture  2701 ″ which correspond to aperture  2406 ″ on securing flange  2515 ″ of toe board frame  2500 ″ to secure toe board  2700 ″ using a bolt (not shown). 
       FIGS. 28A and 28B  show rail post  2000 ″ in detail. As illustrated, rail post  2000 ″ is a tubular post containing a plurality of apertures and/or buttons  2001 ″. It is to be understood that apertures and/or buttons occur in corresponding pairs such that a second set of apertures/buttons is disposed directly opposite the apertures/buttons shown. When securing rail post  2000 ″ to rail post mount  2400 ″, a corresponding pair of apertures/buttons are aligned with apertures  2410 ″ in rail post mount  2400 ″, and rail post  2000 ″ is secured in position. By providing a plurality of aperture/button pairs on rail post  2000 ″, rail post is vertically adjustable within rail post mount  2400 ″ 
     Rail post  2000 ″ also includes rail system securing structures  2002 ″, which are specifically designed for use with chain rail systems (see  FIG. 29 ). Rail system securing structure  2002 ″ is shown in more detail in  FIG. 28B . Rail system securing structure  2002 ″ includes body  2002   a ″ which is secured to rail post  2000 ″ and contains two corresponding pairs of chain slots  2002   d ″/ 2002   e ″. Gravity latch  2002   b ″ is pivotally connected to body  2002   a ″ at the end away from rail post  2000 ″. To secure chain rails to rail post  2000 ″, chains (or string or other flexible rail system) are pushed downward on gravity latch  2002   b ″ over the desired chain slot  2002   d ″ or  2002   e ″. Side extensions  2002   f ″ of gravity latch  2002 ″ are rotated downward while latch body  2002   g ″ is forced upward. Gravity latch  2002 ″ pivots around pivot point  2002   c ″. Once the chain or other rail material clears the side extensions  2002   f ′, gravity latch  2002 ″ causes latch body  2002   g ″ (containing a majority of the mass of gravity latch  2002 ″) to fall back into position, forcing extensions  2002   f ″ upward and thereby closing chain slots  2002   d ″/ 2002   e″.    
       FIG. 29  illustrates an exemplary work platform system similar to  FIG. 25 , except the alternative toe board frame  2500 ″, rail post  2000 ″ and toe boards  2700 ″ are used and a rail system  2800 ″ of flexible chain is installed. In the exemplary embodiment shown, the flexible chain rail system  2800 ″ uses both chain slots  2002   d ″ and  2002   e ″ of a top rail securing structure  2002 ″, with flexible chains extending from one rail post  2000 ″ to the next rail post  2000 ″ and diagonally from the securing structure  2002 ″ of a first rail post  2000 ″ to the securing apertures  2512 ″ ( FIG. 26 ) of flange  2515 ″ ( FIG. 26 ). A second lower rail securing structure  2002 ″ on each rail post  2000 ″ is left available for a second rail system. 
     It should be noted that, although the embodiment of work platform system shown in  FIGS. 1, 3, 7 , etc. is a system in which the suspended subsystem is intended to extend not only generally horizontally between the portions  132 ,  134  of the support subsystem  130  but also generally linearly due to the fact that the suspension bridge  100  itself is a linear structure, it is envisioned that other embodiments of the work platform system can or will need for a suspended subsystem to be implemented in manners that are nonlinear, for example, in a curving manner as illustrated schematically by a suspended subsystem  995  shown in  FIG. 30 . Nonlinear implementations of this type can raise special implementation concerns because, as illustrated in  FIG. 30  for example, although panel sections from different rows may at certain locations be aligned or “in phase”, for example, as shown at a location  997 , at other locations such as a location  999  the panel sections may no longer be aligned or be “in phase”. Although this in and of itself may not always pose a difficulty, difficulties can arise particularly when out of phase panel sections make it difficult to fit in desired suspender structures  800  to allow for desired suspension chains  790  to be installed. Nevertheless, such difficulties can be alleviated through the use of panel sections of differing sizes that allow for reestablishment of alignment among the panel sections of different rows. For example, realignment between the rows of panel sections at the location  997  of  FIG. 30  can be achieved by introducing a row panel in one of the rows that is half of the length of the standard-size row panel being utilized otherwise. 
     From the above discussion, it should be appreciated that the further implemented suspended system  720  of  FIGS. 7 and 12 , as with respect to the suspended system  120  of  FIGS. 1 and 3 , is in a partially completed form. That is, although some of the panels sections  750 , suspension chains  790 , suspender structures  800 , and cover sections  767  are shown to be implemented in relation to  FIGS. 7 and 12 , there nevertheless remain regions along the pairs of wire tendons  230  at which panel sections and other components mentioned above are not yet installed. More particularly, even though  FIG. 7  suggests that the rows of panel sections  753  and  754  may be fully complete rows of the panel sections  750  that extend the full length of the pair of wire tendons  304  in between those rows of panel sections, as shown the other rows of panels  751 ,  752 ,  755 ,  756 ,  757 , and  758  still require the installation of additional panel sections  750 . 
     Nevertheless from the above description, it can be appreciated from  FIGS. 7 and 12  that, upon the addition of further ones of the panel sections  750 , cover sections  767 , suspension chains  790 , and suspender structures  800  along the entire lengths of all of the pairs of wire tendons  230 , the further implemented suspended subsystem  720  will eventually be modified to attain a fully implemented state. More particularly, as shown in  FIG. 15 , completion of this process will result in a fully implemented work platform system  860  provided on suspension bridge  100  as shown, where the fully implemented work platform system not only includes the two portions  132  and  134  of the support subsystem  130  that are mounted on the two towers  140  of the suspension bridge (as already discussed with reference to  FIG. 7 ), but also includes a fully implemented suspended subsystem  120  extending between those two portions of that support subsystem, where the fully implemented suspended subsystem  120  includes multiple ones of the suspension chains  790  along its length that are coupled to the deck  222  of the suspension bridge. 
     More particularly in this regard, it should be evident from the discussion provided in relation to  FIGS. 7, 7A, 7B, and 12  that the further implemented suspended subsystem  720  can be modified to attain the fully implemented suspended subsystem  880  particularly by (a) positioning additional ones of the panel sections  750  along the entire lengths of the pairs of wire tendons  230  so that each of the rows  751 ,  752 ,  753 ,  754 ,  755 ,  756 ,  757 , and  758  includes a full set of the panel sections extending all or substantially all of the distance between the two portions  132  and  134  of the support subsystem  130  mounted on the two towers  140 , (b) coupling sufficient or appropriate numbers of the suspension chains  790  between the deck  222  of the suspension bridge  100  and the wire tendons  230  by way of associated ones of the suspender structures  800 , which also serve to retain in place the panel sections  750  relative to the wire tendons  230 , and (c) providing additional cover structures  767  between the rows of panel sections  751 ,  752 ,  753 ,  754 ,  755 ,  756 ,  757 , and  758  to eliminate any gaps existing between those rows that exist notwithstanding the presence of the suspender structures  800 . 
     To further illustrate steps of implementation/installation/erection of the fully implemented work platform system  860  of  FIG. 15 , a flowchart  900  is further provided in  FIG. 16 , the flowchart illustrating such steps in accordance with exemplary embodiments of the present disclosure. It will be understood that the steps of the flowchart  900  generally correspond to the description already provided above relating to  FIGS. 1-15 and 16-26 . 
     As shown, upon the process commencing at a start step  902 , the process first involves a step  904  of assembling/installing a support subsystem such as the support subsystem  130 . The step  904  includes performing of a first substep  906  that involves assembling and securing a first portion of the support subsystem (e.g., the first portion  132 ) at one end of the structure, and another substep  908  that involves assembling and securing a second portion of the support subsystem (e.g., the second portion  134 ) at another end of the structure. In the substeps  906  and  908 , it will be understood that installation and securing of the respective portions of the support subsystem includes the implementation of any appropriate suspension, anchoring, and/or bracing structures as needed and, additionally, that such installation and securing occurs at a desired elevation or height (e.g., a desired distance above ground level). 
     In accordance with at least some embodiments, a substep  910  is also performed that includes providing and installing structures, such as adaptor brackets (not shown) to each of the support subsystem portions (for example, at leading edges of the support subsystem portions), with this substep serving to ready or configure the respective support subsystem portions to be connected to flexible elements such as the pairs of wire tendons  230  discussed above. Next, in a step  912 , the flexible elements (again, e.g., the pairs of wire tendons  230 ) are secured to the respective portions of the support subsystem, such as by way of the adapter brackets previously mentioned. Attachment of these flexible elements typically will also establish multiple rows between the flexible elements (e.g., between the different pairs of wire tendons). Attachment of the flexible elements begins the installation of the suspended subsystem as discussed above, which ultimately results in the implementation of a fully implemented suspended subsystem such as the fully implemented suspended subsystem  120  and thus, viewed in combination with the support subsystem  130 , implementation of a fully implemented work platform system such as the fully implemented work platform system  110  mentioned above. 
     Upon the flexible elements being attached, then the process advances to a step  914  that involves installing panel sections such as the panel sections  750 . The step  914  includes several substeps  916 ,  918 ,  920 ,  922 , and  924  as shown. The substep  916  is initially performed as one starts installation of the panel sections at one end of structure, e.g., at the first portion  132  discussed above. This substep involves placing a plurality of the panel sections on a plurality of the flexible elements and securing the panel sections to a portion of the support subsystem  130  (again, e.g., the first portion  132 ) and can involve the implementation of specialized panel structures or other structures that allow for a smooth transition (e.g., a smooth floor surface) to be maintained as one proceeds from the support subsystem to the suspended subsystem. 
     Next, at the substep  918 , the process includes placing subsequent or additional ones of the panel sections  750  on a plurality of the flexible elements and securing such subsequent or additional panel sections to the respective previous panel sections using handle support extensions such as the handle support extensions  780  discussed above. This step is typically performed with respect to each of the rows of the suspended subsystem as established by the different flexible elements. Further, this step of placing and securing the panel sections  750  in at least some embodiments can involve positioning and lowering of panel sections in a particular manner. For example, positioning and lowering of a panel section can be performed entirely by hand by work personnel, or by way of machinery, and/or involve an extension connector such as a lanyard. In the case where a lanyard or similar ropelike connector was utilized, such connector would be attached to the handle support extensions tending to rotate away from the work personnel during installation of the panel section (e.g., the handle support extensions that would be at the top of the additional panel section  791  if it was shown in  FIG. 11A ) and, by way of holding the unattached end of the lanyard, the work personnel could lower the panel section in a controlled manner. Substep  918  can also include activating one or more gravity latches. 
     Further, at the substep  920 , tendon retainer structures  769  are installed in relation to the flexible elements, typically at desired, predetermined and/or specified locations along the flexible elements. Although shown as occurring sequentially after the substep  918 , it is contemplated that the substep  920  can take place generally as the panel sections  750  are placed on the plurality of flexible elements in accordance with the substep  918 . In some embodiments, substep  918  can be omitted entirely. Additionally, at the step  922 , the additional cover structures  767  are installed and secured to the tendon retainer structures using retaining or connecting structures (e.g., bolts such as the bolt  982 ). This substep  922  also can take place generally as the panel sections  750  are placed on the plurality of flexible elements. Finally, as indicated by the substep  924 , in some embodiments a guard railing system also is installed with respect to the panel sections  750  and it is contemplated that this substep too can take place generally as panel sections  750  are placed on the plurality of flexible elements. The guard railing system can be implemented by attachment of guard rail structures to a variety of other structures including, for example, retainer brackets such as the bracket  980  or features such as the orifices  781  associated with the panel sections. 
     Next, as represented by a step  926 , installing of platform suspension structures takes place, and this includes substeps  928 ,  930 , and  932  as shown. Although shown in the flowchart  900  of  FIG. 16  as occurring subsequent to the installing of the panel sections in accordance with the step and substeps  914 ,  916 ,  918 ,  920 ,  922 , and  924 , in other embodiments the step  926  and associated substeps  928 ,  930 , and  932  can occur substantially contemporaneously with the step and substeps  914 ,  916 ,  918 ,  920 ,  922 , and  924 . As indicated, the substep  928  involves installing and securing suspender bracket structures, such as the suspender structures  800 , to the flexible elements (again, e.g., the wire tendons  230 ) at desired, predetermined and/or specified locations. Next, the substep  930  is performed, which includes installing and securing suspension structures (e.g., the suspension chains  790 ) to beam clamps or other portions/members of the structure in relation to which the work platform system is being implemented (e.g. to locations along the deck  222  of the suspension bridge  100 ) at desired, predetermined and/or specified locations along the structure. 
     Then, at the further substep  932 , adjustment (e.g., raising or lowering) of the elevation of the panel sections  750  (connected to the flexible elements) and additionally securing (for example, using a chain retaining structure as previously described) of the suspension structures to the suspender bracket structures are performed. For example, one or more of the suspension wires  790  can be attached to the suspender structures  800  by way of the intermediate orifice(s)  822  thereof such that tension is applied to the structures  800  and thus to the flexible elements. It should be noted that tools, such as a suspender adjustment tool, can be used to adjust or accomplish elevation adjustment. Additionally, it should also be noted that the process of installing the suspender bracket structures such as the suspender structures  800  at the substep  928  can particularly involve positioning the suspender structures  800  onto the flexible elements and then rotating and tightening the grasping portions  830  so as to affix the suspender structure(s) to the flexible elements (and also so that the ends of panel sections  750  are locked in place between the grasping portions  830  and the top planar surfaces  802  of the suspender structures). Depending upon the embodiment, the suspension wire(s) can alternatively be coupled to the structures  800  prior to the grasping portion(s)  830  being rotated and locked in place relative to the flexible elements. 
     If at the step  936  it is determined that the installation of panel sections  750  is not complete with respect to any one or more of the rows of panel sections, the steps and substeps associated with installation of the panel sections  750  and platform suspension structures continues are repeated, by returning to step  914 . It should be noted that, in this circumstance, upon repeating the substeps associated with the step  914  in particular, the substep  916  typically would no longer be applicable and would be skipped (since implementation of the panel sections would typically no longer be occurring right at the junction between the support subsystem and the flexible elements). Accordingly, the steps and substeps  914 - 936  are generally repeated until the other end of the structure (e.g., the second portion  134 ) is reached. That said, upon it being determined at the step  936  that the installation of panel sections  750  is complete with respect to all of the rows, the panel sections will be finally secured (e.g., using an adaptor bracket structure), at step  938 , at the second portion of the support subsystem (e.g., the portion  134 ), and then the process concludes at the step  940 . It should be appreciated that, although the flowchart  900  envisions that installation is complete when a far end of the suspended subsystem (e.g., at the portion  134 ) has been reached, completion also could be achieved, in other embodiments, by reaching some other location or attaining some other level of implementation. 
     In further, embodiments, the flowchart  900  can include additional steps or substeps depending on the particular use of a suspended subsystem and/or the use of any optional components. For example, flowchart  900  can include the further steps or substeps of installing a toe board frame, installing a toe board, installing a rail post mount, installing a rail post and/or forming a rail system. Flow chart  900  can also include further substeps for the installation of additional cover portions, as described with reference to  FIGS. 18I-18N . It should be appreciated that the additional steps or substeps are not limited to those above, and the above-recited steps or substeps can include further substeps. 
     It should be appreciated that the work platform assembly, subsystems, and components thereof, and methods of implementation/installation and utilization relating thereto that are described above are advantageous in one or more respects depending upon the embodiment. For example, the intermeshing handle or grasping portions  830  allow not only for supporting the panel sections  750  but also act as support extensions and allow adjacent panel sections to be linked to one another and to provide support for and self-brace one another (e.g., the grasping portions  830  of one panel section extending beneath the side strut of an adjacent panel section help to provide further support for that adjacent panel section). Indeed, the grasping portions/support extensions  830  facilitate keeping the top panel surfaces of adjacent ones of the panel sections substantially aligned with minimal changes in elevation of the top panel surfaces of neighboring panel sections relative to one another. The panel sections  750  also are easy for stacking and shipping. 
     Also, through the use of appropriately-positioned ones of the tendons  230 , the overall working surface (e.g., the surface on which work personnel walk) provided by the work platform system is substantially flat. Further, through the use of pairs of tendons, rather than single tendons, extending between the support subsystem (platforms) and supporting the panel sections, significant redundancy is built into the work platform system. Additionally, numerous components of the work platform system are modular and/or interchangeable, and/or can be reused again and again in relation to the implementation of new work platform systems in relation to additional structures. 
     It should also be appreciated that the work platform assembly, subsystems, and components thereof, and methods of implementation/installation and utilization relating thereto that are described above are only intended as examples, and the present disclosure is intended to encompass numerous variations of the above-described concepts. For example, a variety of panel sections of different sizes and shapes can be employed depending upon the embodiment and, indeed, in some embodiments, panel sections of different sizes and shapes are implemented together in a single work platform system. The use of panel sections of different widths and/or lengths can also be appropriate depending upon the circumstance. For example, in some embodiments or circumstances, panel sections having different sizes in terms of the width dimension discussed above (e.g., the width dimension  759  of  FIG. 8 ) extending between different pairs of the wire tendons can be appropriate for different rows, to accommodate variable spacing of the wire tendons of different pairs of those wire tendons. This can be appropriate, further for example, to accommodate variable spacing between different ones of the hubs of  310  of the support system to which the wire tendons at their ends are attached. 
     Also, in some embodiments or circumstances, panel sections having different sizes in terms of the length dimension discussed above (e.g., the length dimension  761  of  FIG. 8 ) can be provided. The use of panel sections having different lengths allows for the overall work platform system to be advantageously implemented as necessary in view of the environment and other circumstances. For example, the use of panel sections of different lengths allows the panel sections to more closely be fit to obstacles (e.g., a pipe sticking from a bridge structure), curve platform fit contoured structures, or provide an ability to space wire tendon support extensions (which also can be referred to as tendon hooks)  770  in a manner that facilitates the installation of suspender structures  800 . Further, in some embodiments, any of a variety of different numbers and types of handle support extensions (or simply interlocking handles) can be employed for interlocking or linking any two or more of the panel sections, and the handle support extensions need not be identical in number, size, or shape to the handle support extensions  780  shown in  FIG. 8 . 
     The use of handle support extensions can provide numerous functions including, for example: (a) securing panel sections together during assembly so that the panel sections do not slide apart from one another; (b) improving of the ease of platform assembly, insofar as the handle support extensions provide guidance and support for panel sections during assembly and disassembly; (c) increasing panel section stiffness by virtue of allowing for the transfer of loads from one panel section to another panel section; (d) minimizing the degree to which neighboring panel sections have surfaces that are not aligned (e.g., eliminating steps between neighboring panels and enhancing the degree to which the various neighboring panel sections form an overall surface that is substantially flat); (e) facilitating the assembly of panel sections in applications where the work platform system is extending downhill, by preventing panel sections from sliding away before the panel sections can be secured to wire tendons/cables; and/or (f) facilitating the handling, packing and securement of panel sections prior to delivery of the panel sections to a jobsite. 
     As already indicated above, the particular number, size, shape, and arrangement of handle support extensions associated with a given panel section can vary depending upon the embodiment or circumstance. Although in some work platform systems all of the panel sections will have identical handle support extensions, in other embodiments, one or more panel sections can have first arrangement of one or more handle support extensions even while one or more other panels sections have another arrangement of one or more handle support extensions. Among the various possible arrangements of handle support extensions that are possible are the following, for example: (a) a first arrangement in which there is only a single handle support extension on one side of a panel section; (b) a second arrangement in which there are two or more handles on only one side of a panel section (but no handle support extensions on the other side of the panel section); (c) a third arrangement in which there is a single handle support extension (but not more than one such extension) on each side of the panel section; and (d) a fourth arrangement in which there is more than one handle support extension on both of the sides of the panel section. 
     It should further recognized that the present disclosure is intended to encompass handle support extensions that have any of a variety of different shapes, as well as panel sections that include not only one or more handle support extensions but also one or more other features that serve one or more of the purposes of the handle support extensions as well. For example, in some embodiments, a panel section can include a flat U shaped handle support extension that serves to support adjacent panel section (such a handle support extension would be positioned so as to extend under a side strut of a neighboring panel section). Alternatively for example, in some embodiments, a panel section can include a flat U shaped handle support extension that serves to support an adjacent panel section and that also serves to receive or accept an interlocking device from the adjacent panel section. 
     Further for example, in some embodiments, a panel section can include a flat U shaped handle support extension that serves to support an adjacent panel section and the panel section can further include an additional feature that is configured to interlock with the adjacent panel section (or configured to receive an interlocking feature of the adjacent panel section). Additionally for example, in some embodiments, the panel section can include a U shaped handle with a 90 degree bend on one side only to secure adjacent panel sections together, as already discussed with reference to  FIG. 8 . And numerous other possible arrangements of handle support extensions are possible an encompassed herein as well. Also, it should be appreciated that in some alternate embodiments the support extensions referred to herein as handle support extensions need not at all be directed to (or need not primarily be directed to) serving as handles by which work personnel (or machinery) can grasp or lift or move the panel sections on which those support extensions are formed. That is, in at least some alternate embodiments, the panel sections can include one or more support extensions that are configured to allow a given panel section to provide support for and/or to be positioned in relation to (or be attached to) an adjacent panel section in a given row of panel sections (or in another arrangement of neighboring panel sections) even though such support extensions are not configured as, or employed as (or configured primarily as, or employed primarily as) handles. 
     Although the embodiments discussed above employ pairs of wire tendons (or other flexible linkages or elements) such as the pairs of wire tendons  301 ,  302 ,  303 ,  304 ,  305 ,  306 ,  307 ,  308 , and  309  and employs wire tendon support extensions (or tendon hooks) such as the extensions  770  that are suited for such pairs of wire tendons insofar as the extensions have dual indentations (or notches)  772  that can be used to locate and support the panel sections on the pairs of wire tendons, it should be appreciated that such wire tendon support extensions can also be used in embodiments where only single tendons are situated adjacent to the panel sections (e.g., in embodiments where rows of the panel sections are situated between single wire tendons. Indeed, although it is envisioned that the use of pairs of wire tendons can be advantageous in that it can provide redundancy and greater system strength and robustness, and can facilitate balanced clamping of other structures to the wire tendons (e.g., balanced clamping of the tendons by the suspender structures  800  or tendon retainer structures), nevertheless it should be appreciated that all or substantially all of the components of the fully implemented work platform system (including, for example, the suspender structures  800 ) also can be employed in a work platform system that only employs single tendons running in between adjacent rows of panel sections (or running adjacent to a row of panel sections). 
     Additionally, numerous subcomponents of the fully implemented work platform system  860  have particular features that offer a variety of capabilities and advantages. For example, with respect to the suspender structures  800 , the handle portions  816  facilitate easy handling/grasping of the suspender structure while also providing the necessary section required for strength and stiffness of the suspender structure so that the structure can bear suspender loads. Also for example, the tendon retainer structures (or rotating cable structures)  769  facilitate fast and simple installation and securement of the tendon retainer structure (or bracket) to single or dual tendon arrangements. Further, in some embodiments, one or more of the suspender structures or tendon retainer structures includes an indicating pin providing a visual indicator indicating whether proper assembly or implementation (e.g., proper clamping onto one or more tendons) of the suspender structure or tendon retainer structure has been achieved. Also, in some embodiments, a visual indicator associated with the suspension structure can facilitate fast, simple and visually verifiable securement of a suspension chain to the suspender structure. 
     Further for example, it should be appreciated that each of the intermediate orifices  822  of the suspender structures  800 , due to the presence of the pairs of end slot regions  823  and intermediate transverse slot regions  825 , serves as a dual chain slot by which the suspender structure  800  can be attached not merely to one but rather to more than one (e.g., two) of the suspension chains  790  or other linkages or extensions or connectors. Also, each of the intermediate orifices  822  facilitates use of a suspender adjustor to install the suspender structure  800 . Further, in some embodiments or circumstances, the intermediate orifices  822  can be employed to allow for the installation of wind bracing chains in relation to the suspender structures  800 . Additionally, it should be appreciated with respect to the tendon retainer structures  769  that these structures not only can provide connective structures by which the additional cover structures (or gap fillers)  767  can be affixed to the wire tendons, where the additional cover structures then further serve to prevent movement of the panel structures  750  away from the wire tendons (e.g., to prevent uplifting of the panel structures), but also the tendon retainer structures also provide connection structures by which retainer bracket can be secured in relation to the wire tendons, where the containment brackets are secured to the tendon retainer structures (at locations above the additional cover structures) and can further receive and support vertical and horizontal containment wire ropes. 
     It should further be appreciated that, although in at least some embodiments the work platform systems encompassed herein include both a suspended subsystem and a support subsystem, where the support subsystem includes components (such as the hubs  310  and joists  330 ) corresponding to the QuikDeck™ suspended access system mentioned above, this need not be the case in all embodiments. Use of a support subsystem that includes components corresponding to the QuikDeck™ suspended access system can be advantageous for any of a number of reasons including, for example, that implementation of platforms in accordance with the QuikDeck™ suspended access system can serve to provide robust anchorages at multiple locations for securing the wire tendons (e.g., the pairs of wire tendons  230 ) of the suspended subsystem. Indeed, such platforms provide a robust and stable surface that facilitates installation of the wire tendons. 
     However, notwithstanding these advantages of implementing a suspended subsystem in relation to support subsystems (platforms) in accordance with the QuikDeck™ suspended access system, the present disclosure nevertheless is also intended to encompass embodiments that utilize other types of support subsystems, and nothing herein should be interpreted as indicating any requirement that the QuikDeck™ suspended access system or any of the particular support subsystem components or variations described herein be employed. Indeed, the present disclosure is intended to encompass work platform systems that only include one or more suspended subsystem components or that only include what can be considered a suspended subsystem, with that suspended subsystem being directly coupled to structures of interest such as the suspension bridge  100  without there being present any support subsystem whatsoever. 
     Additionally, regardless of the particular suspended subsystem or support subsystem components that are used, numerous other variations are intended to be encompass herein as well. For example, although the fully implemented work platform system  860  only includes a single platform level, in other embodiments there can be multiple levels of platform structures. Further, in some embodiments other types of components can be also included in the work platform system. For example, in some embodiments, a railing system can be attached to one or more portions of the work platform system (e.g., one or more portions of the support and/or suspended subsystems of the work platform system). Railings of such systems can be manufactured from a variety of materials, such as chain, cable (e.g., galvanized aircraft cable), line, and the like, among other things and, in still additional embodiments, railing standards can also be used to erect a work enclosure system. For example, tarps, sheeting, or the like can be attached to railing standards to enclose work area(s) for various purposes. 
     The materials out of which the work platform system  860  or other work platform systems in other embodiments can be formed can vary depending upon the embodiment. For example, suitable materials for components of such work platform systems can include metal (e.g., steel, aluminum, etc.), wood, plastic, composite, or other suitable materials. Also, such components can be made of items that are solid, corrugated, grated, smooth, or of other suitable configurations. For example, panel portions of such work platform assemblies can be made of wood sheeting, plywood, roof decking material, metal on a frame, grating, steel sheeting, and the like, among other things. 
     Further for example, each of the suspension chains of the suspended subsystem (e.g., the suspension chains  790 ) and support chains of the support subsystem (e.g., the support chains  220 ) can take the form of any of a variety of types of chains, including toothed chains, suspension wires or wire tendons, belts, or other support components depending upon the embodiment. Also, the wire tendons of the suspended system (e.g., the wire tendons of the pairs of wire tendons  230 ) can additionally take on any of a variety of forms of wires, cables, and similar flexible extending structures. Indeed, it should be appreciated that, depending upon the embodiment or circumstance, any of a variety of types of bendable or flexible linkages or extensions or flexible machine elements (or simply flexible elements) can be employed in the roles of each and every one of the suspension chains  790 , support chains  220 , and wire tendons  230 , such as wire, wire rope, chain (or toothed chain), belt, or similar types of extensions or linkages or connectors. 
     Further in this regard, it should be noted that typically the extensions or linkages or connectors will be structures that are flexible and that have lengths along linear dimensions that are substantially greater than the widths and depths of those structures, where the widths and depths are themselves both small relative to the lengths and the widths and depths are themselves similar in size. Nevertheless, in some alternate embodiments, it is possible that the extensions or linkages or connectors can be structures having other characteristics including, for example, structures that have lengths that are substantially greater than their widths, as well as widths that are substantially greater than their depths (e.g., structures taking the form of ribbons). Also, it is possible in some cases that one or more of the extensions or linkages or connectors used as (or in place of) the suspension chains  790 , support chains  220 , and/or wire tendons  230  can be rigid rather than flexible. 
     In at least some embodiments, portions of the work platform system described herein can interface with, connect with, or interoperate with portions of conventional work platform systems. Also, in at least some embodiments, work personnel can extend, relocate, or remove components of the work platform system using only hand tools, and no mechanical tools, hoists, cranes, or other equipment is required to add to, or subtract from, existing components of the work platform system. In at least some embodiments, installation of the work platform system can be done, essentially, “in the air”. That is, the work platform system can be erected and connected together “in the air”, in a piece-by-piece order via the use of multiple pieces of lifting, or hoisting, equipment. That said, in alternate embodiments, it is possible also that one or more of the subsystems, portions, or components will be preassembled on the ground, or at a remote location, and then moved and hoisted as a pre-assembled module into the desired location. 
     It should also be understood that, in addition to the processes of implementation/installation and use described herein, the present disclosure is also intended to encompass other processes such as disassembly processes. For example, to the extent that a process for installing panel sections  750  is discussed above, and can involve a worker lowering one of the panels by of a lanyard or similar ropelike structure, disassembly can similarly involve tugging on a lanyard to raise up a previously-installed panel. In such circumstance, the lanyard would be attached to the handle support extension(s) of the panel section being removed that extend from the side strut of that panel section opposite the location of the work personnel pulling on the lanyard. 
     Therefore, although certain embodiments of the present disclosure have been shown and described in detail above, it should be understood that numerous changes and modifications can be made without departing from the scope of the appended claims. For example, the above described work platform systems may include various embodiments and combination of embodiments of the various components described herein. Nonlimiting examples of embodiments of the present disclosure are provided below.
