     STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT 
     Not Applicable 
     BACKGROUND 
     1. Technical Field 
     The present disclosure generally relates to devices and methods for positioning pre-fabricated wall sections, and more particularly, to a wall lifting, transport and positioning device for use with a wall section upon a worksite surface. 
     2. Related Art 
     Prefabricated wall panels or wall sections have continued to gain increased popularity due to the relative efficiency in the onsite construction of a structure. These pre-fabricated or pre-engineered wall sections are constructed offsite and delivered to a worksite location ready to be erected. This saves significant onsite construction time and labor to build a similar wall section which then must be erected. The wall sections are delivered to worksite location and may be temporarily stored in horizontal stacked configuration. A wall section may typically come is 8′-12′ lengths with heights of 8′-12′ depending upon a desired ceiling height. The various components of a wall section may be formed of 2″ by 4″ or 2″ by 6″ cross sections of lumber. The wall sections each include a horizontal top plate, a horizontal bottom plate and a plurality of vertical studs extending between the top and bottom plates at spaced intervals. The wall sections are also referred to as stud framed walls. This classic arrangement is configured to withstand in-plane shear loading of the associated structure. As such the wall sections are also referred to as shear walls. 
     The bottom plate is set generally upon a subfloor or foundation. The bottom plate has bolt holes form through them. Inset in the subfloor or foundation are corresponding anchor bolts that are configured to engage the wall sections through the bolt holes for securely anchoring the wall sections to the subfloor or foundation. A foundation U-channel or track is disposed upon the subfloor or foundation that extends the length of the bottom plate. The anchor bolts extend upwards through holes in the foundation U-channel. When erecting the wall section in a vertical configuration, the entire wall section must be lifted vertically above the foundation U-channel and the anchor bolts. The bolt holes must be precisely aligned with the anchor bolts and then the entire wall section is lowered into the foundation U-channel with the bolts extending through the bolt holes. 
     The proper installation of a wall section is a labor intensive and time consuming process. A large number of workers are required to erect, position and install a wall section due to its physical weight and geometry. This contemplated to interrupt workers who must stop their tasks at the worksite to help with the wall section. Moreover, this installation process presents significant safety issues as well. 
     The first step in the installation process is that the wall section must be physically lifted and moved adjacent the installation location. The bottom plate is aligned along the foundation U-channel. Next, the wall section must be tilted up to a vertical position, and then dead-lifted upward and translated over the foundation U-channel. The entire wall section must be precisely positioned to align the bolt holes with the anchor bolts extending through the foundation U-channel. All the while, the entire wall section is being physically held. Finally, the wall section is lowered in place with the bolts engaged with the bolt holes. 
     Accordingly, there is a need in the art for an improved device and method of lifting, transporting and/or positioning wall sections. 
     BRIEF SUMMARY 
     According to an aspect of the invention, there is provided a wall lifting, transport and positioning device for use with a wall section upon a worksite surface. The wall section is rectangular and has a horizontal top plate and an opposing horizontal bottom plate. The top plate has a lower top plate side facing towards the bottom plate. The bottom plate has a lower bottom plate side facing away from the top plate. The lower top plate side and the lower bottom plate side define a lifting wall height there between. The device includes a wheeled hand cart housing, a support frame, a pair of roller pins, and a lifting actuator. The roller pins extend from the support frame away from the wheeled hand cart housing. The roller pins are horizontally aligned and positionable at least the lifting wall height above the worksite surface. Each of the roller pins include an outer cylindrical element configured to rotate relative to the support frame with the lower top plate side being positioned in contact with the outer cylindrical element for translation of the wall section in a direction along the top plate. The lifting actuator is disposed between the wheeled hand cart housing and the support frame. The lifting actuator is sized and configured to translate the roller pins upward relative to the wheeled hand cart housing with the outer cylindrical elements being positionable under and in contact with the lower top plate side. It is contemplated that the roller pins are particularly advantageous in that they allow for an ease of positioning of the support wall section. This is particularly important as this allows for proper alignment and positioning of the wall section during its installation process. Furthermore, it is contemplated that such process may be safely accomplished with a minimal amount of physical labor and number of workers involved. 
     According to various embodiments, the lifting actuator and the support frame may be cooperatively sized and configured to translate the roller pins upward relative to the wheeled hand cart housing with the outer cylindrical elements being positionable under and in contact with the lower top plate side and the wall section being laterally supported by support frame. The support frame may be generally planar. The support frame may be disposed at an angle with respect to the vertical plane with the cart disposed upon the worksite surface. The support frame may be generally disposed at an angel generally between 5 degrees and 20 degrees, such as at approximately 8 degrees with respect to the vertical plane with the cart disposed upon the worksite surface. 
     The lifting actuator may be a hydraulic device. The lifting actuator may include a cylinder that is configured to move relative to the wheeled hand cart housing.

The wheeled hand cart housing may further include a pair of wing braces disposed between and connected to the housing frame and the main support base, and the wing braces may respectively extend laterally from the main support base. 
     According to another aspect of the invention, there is provided a method of positioning a wall section within a foundation U-channel. The wall section is rectangular and has a horizontal top plate and an opposing horizontal bottom plate. The top plate has a lower top plate side facing towards the bottom plate, and the bottom plate has a lower bottom plate side facing away from the top plate. The method includes moving a wall lifting, transport and positioning device upon a worksite surface adjacent the wall section. The wall section is disposed in a horizontal position. The device includes a wheeled hand cart housing, a support frame, a pair of roller pins extending from the support frame away from the wheeled hand cart housing, and a lifting actuator disposed between the wheeled hand cart housing and the support frame. The lifting actuator is sized and configured to translate the roller pins upward relative to the wheeled hand cart housing. The method further includes tilting the wall section to position the lower top plate side above the pair of roller pins. The method further includes lifting the wall section off of the worksite surface by actuating the lifting actuator. The method further includes moving the device along the worksite surface to position the bottom plate above and along the foundation U-channel. The method further includes translating the wall section with the lower top plate side rolling along the roller pins. The method further includes lowering the wall section with the bottom plate disposed in the foundation U-channel by actuating the lifting actuator. 
     According to various embodiments, the method may further include lifting the top plate to move the wall section from the horizontal position to a vertical position with the bottom plate disposed adjacent a worksite surface and the top plate disposed above with bottom plate. The foundation U-channel may have a side wall defining a side wall height, and the method may further include lifting the wall section off of the worksite surface at least the side wall height. 
     The bottom plate may include a plurality of anchor bolt holes and the a plurality of anchor bolts vertically extend from within the foundation U-channel, and the method may further include aligning the anchor bolt holes with anchor bolts.

     This application is a continuation-in-part application of U.S. patent application Ser. No. 13/444,080 (the entire contents of which are hereby incorporated by reference) filed on Apr. 11, 2012 and claims of benefit of such earlier filing date of such parent application. The detailed description set forth below in connection with the appended drawings is intended as a description of the presently preferred embodiments of the invention, and is not intended to represent the only form in which the present devices may be developed or utilized. It is to be understood, however, that the same or equivalent functions may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention. It is further understood that the use of relational terms such as first, second, and the like are used solely to distinguish one from another entity without necessarily requiring or implying any actual such relationship or order between such entities. 
     Referring now to  FIG. 1  there is depicted a side perspective view of a wall lifting, transport and positioning device  10 .  FIG. 2  is a side perspective view of the device  10  of  FIG. 1  with a wall section  12 .  FIG. 3  is a side view of the device  10  of  FIG. 1 .  FIG. 10  is an end view of the device  10  of  FIG. 1 .  FIG. 11  is an end view of the device  10  of  FIG. 2  with the wall section  12  with the device  10  upon a worksite surface  14 . 
     According to an aspect of the invention, there is provided the wall lifting, transport and positioning device  10  for use with the wall section  12  upon a worksite surface  14 . The wall section  14  is rectangular and has a horizontal top plate  16  and an opposing horizontal bottom plate  18 . The top plate  16  has a lower top plate side  20  facing towards the bottom plate  18 . The bottom plate  18  has a lower bottom plate side  22  facing away from the top plate  16 . The lower top plate side  16  and the lower bottom plate side  20  define a lifting wall height there between (denoted “LWH” on  FIG. 11 ). 
     The device  10  includes a wheeled hand cart housing  24 , a support frame  26 , a pair of roller pins  28   a,b  extending from the support frame  26  away from the wheeled hand cart housing  24 , and a lifting actuator  32  disposed between the wheeled hand cart housing  24  and the support frame  26 . The roller pins  28   a,b  are horizontally aligned. The roller pins  28   a,b  are positionable at least the lifting wall height (LWH) above the worksite surface  14 . Each of the roller pins  28   a,b  include an outer cylindrical element (respectively denoted  30   a,b ) configured to rotate relative to the support frame  26  with the lower top plate side  20  being positioned in contact with the outer cylindrical element  30   a,b  for translation of the wall section  12  in a direction along the top plate  16 . The lifting actuator  32  is sized and configured to translate the roller pins  28   a,b  upward relative to the wheeled hand cart housing  24  with the outer cylindrical elements  30   a,b  being positionable under and in contact with the lower top plate side  20 . It is contemplated that the roller pins  28   a,b  are particularly advantageous in that they allow for an ease of positioning of a support wall section  12 . This is particularly important as this allows for proper alignment and positioning of the wall section  12  during its installation process. Furthermore, it is contemplated that such process may be safely accomplished with a minimal amount of physical labor and number of workers involved. 
     As used herein the top plate  16  generally refers to a horizontal structural member of the wall section  12  that is adjacent an upper portion of the wall section  12  when the wall section  12  is in an installed vertical position. The top plate  16  may be composed of one or several elements, such as several stacked 2″×4″. As used herein the lower top plate side  20  refers to the horizontal surface of the top plate  16  that is engageable by the roller pins  28   a,b.    
     In further detail, the wheeled hand cart housing  24  may include a housing frame  34 . A main support  38  may extend from the housing frame  34 . A main support base  36  may be attached to the housing frame  34  proximate an end of the housing frame  34 . In this embodiment, the main support  36  is the primary structure to which the support frame  26  is itself supported. The main support  38  may take the form of an I-beam. The support frame  26  may take advantage of this geometry and utilize a roller configuration to engage an interior of the I-beam shaped main support  38  through the use of a roller assembly  40 . In the perspective side view of  FIG. 1 , the roller assembly  40  is depicted as being engaged with the main support  38 . It is understood that another similarly configured roller assembly  40  is likewise engaged with the main support  38  from the opposite side (not visible in this side&#39;s view). The lifting actuator  32  is disposed proximate the main support  36  at an end of the housing frame  34 . In this regard, also located adjacent thereto is a hydraulic tank  42  and control unit  44  of the lifting actuator  32  which are configured to actuate the lifting actuator  32 . The device  10  further may include a counter-weight  46  disposed upon the wheeled hand cart housing  24 . In this embodiment, the counter-weight  46  is disposed upon the housing frame  34  at an opposite end of the location of the main support  38 , the hydraulic tank  42  and the control unit  44 . It is contemplated that the support frame  26  is supported by the main support  38  as well as any supported wall section  12 . In this regard, the counter-weight  46  is used for stability by redistributing the center of gravity of the overall device  10  with a wall section  12 . 
     The device may further include a pair of main wheels  48   a,b  mounted to the wheeled hand cart housing  24 . The main wheels  48   a,b  are attached to the housing frame  34  at a same end as the main support  36  proximate the “loading” end of the device  10 . The device  10  may further include a steerable wheel, such as the pair of steer wheels  50   a,b  mounted to the wheeled hand cart housing  24 . The steer wheels  50   a,b  are attached to the housing frame  34  opposite the main wheels  48   a,b . A steering handle  52  is attached to the steer wheels  50   a,b  and configured to pivot the steer wheels  48   a,b  for steering movement of the device  10 . 
     The lifting actuator  32  may take the form of any number of devices, and any number of off-the-shelf devices may be used that satisfy force, size, cost, mobility and weight requirements. For example, the lifting actuator  32  may be a hydraulic device that may be modified for use in this particular application, such as a log splitter model M1108M.1 manufactured by Northern Tool+Equipment Co., Inc. of Burnsville, MN, for example. Other devices may include pneumatic, gear rack and screw-drive devices as well. The lifting actuator  32  may include a cylinder  54  that is configured to move relative to the wheeled hand cart housing  24 . As such, the cylinder  54  may be a piston that is reciprocally translated which in turn is mechanically connected to the support frame  26  for ultimately effecting vertical movement of a supported wall section  12 . The lifting actuator  32  may be chosen from any of those devices which are well known to one of ordinary skill in the art. 
     The lifting actuator and the support frame  26  may be cooperatively sized and configured to translate the roller pins  28   a,b  upward relative to the wheeled hand cart housing  26  with the outer cylindrical elements  30   a,b  being positionable under and in contact with the lower top plate side  20  and the wall section  12  being laterally supported by support frame  26 . In the embodiment depicted, the support frame  26  is generally planar. In this regard, the support frame  26  is contemplated to laterally support the wall section  12  through a generally distributed contact therewith. As will be discussed further below, the support frame  26  may be disposed at an angle (denoted angle “A” on  FIG. 3 ) with respect to the vertical plane with the cart housing  24  disposed upon the worksite surface  14 . The support frame  26  may be generally disposed at an angel generally between 5 degrees and 20 degrees, such as at approximately 8 degrees with respect to the vertical plane with the cart housing  24  disposed upon the worksite surface  12 . It is contemplated that while the support frame  26  in the embodiment depicted includes various members in a truss-like configuration, the support frame  26  need only provide physical support of the roller pins  28   a,b  and a mechanical means for effecting the translation of force from the lifting actuator  32  to the roller pins  28   a,b.    
     The support frame  26  may include vertical supports  56   a - c . Each of the vertical supports  56   a - c  includes crossbar attachment openings  58   a - c  along the vertical supports  56   a - c . The crossbar attachment openings  58   a - c  are used to engage a main crossbar  60 . In the embodiment depicted, the main crossbar  60  is engaged with the crossbar attachment openings  58   a  of the vertical support  56   a - c . The crossbar attachment openings  58   a - c  correspond to varying positions or heights of the main crossbar  60 . In this regard, the crossbar attachment openings  58   a - c  may cooperatively sized and configured to correspond to various wall sections (such as for standard wall sections used in the construction of 9′, 10′ and 11′ ceilings for examples). As such, the roller pins  28  may be attachable at varying heights along the support frame  26 . End caps  62  may be removeably affixed to opposing ends of the main cross bar  60 . Locking pins  64  may be used to engage the main crossbar  60  with the vertical support  56   b  at a selected one of the crossbar attachment openings  58   a - c  (depicted as being at the crossbar attachment opening  58   a ). The support frame  26  may further include the main cross bar  60  that is sized and configured to rotateably support the roller pins  28   a,b . The roller pins  28   a,b  may be removeably attached to the support frame  26  at the pin supports  64   a,b . The roller pins  28   a,b  are each configured to rotate about an axis  70 . Each of the roller pins  28   a,b  may include a shaft with the outer cylindrical elements  30   a,b  disposed about each shaft. A bearing assembly may be used to facilitate ease of rotation of the outer cylindrical elements  30   a,b . The roller pins  28   a,b  may be chosen from those which are well known to one of ordinary skill in the art. Each shaft may be configured to be removable fixed to the support frame  24 , such as at the main cross bar  60 . Though not depicted locking pins may be used to secure the roller pins  28   a,b  for example. The support frame  26  may further include support arms  66   a,b . The support arms  66   a,b  mechanically span between the main cross bar  60  and each roller assembly  40 . 
     It is contemplated that the device  10  may be utilized for the construction of wall sections not only on a bottom floor of a building structure but with other floors. In this regard, because the device  10  is relatively compact or light weight in comparison to vehicle and motorized construction equipment, the device  10  may be lifted via a fork lift and placed upon an immediate upper floor. 
     With the foregoing general device configurations having been described above, further understanding of the particular advantages of aspects of the invention may be best understood with a discussion of how the device  10  may be utilized. Referring now to  FIG. 4  there is depicted the side view of the device of  FIG. 3  as shown with the wall section  12  and additional wall sections  72   a - c  all arranged in a horizontal stack upon the worksite surface  14 . A foundation U-channel  74  (such as is depicted in the side view of  FIG. 8  discussed further below) may be provided that is positioned at desired location for the installation of the wall section  12  upon the worksite surface  14 . 
     According to an aspect of the invention, there is provided a method of positioning the wall section  12  within the foundation U-channel  74 .

The method further includes moving the device  10  along the worksite surface  14  to position the bottom plate  18  above and along the foundation U-channel  74 . The foundation U-channel  74  may have a side wall defining a side wall height, and the method may include lifting the wall section  12  off of the worksite surface  14  at least the side wall height. 
     Anchor bolts (such as anchor bolts  76   a - c ) are distributed along the foundation U-channel  74 . The anchor bolts  76   a - c  may be set within a concrete foundation and extend through the worksite surface  14 . The anchor bolts  76   a - c  may take the form of J-bolts. The foundation U-channel  74  may have holes that are configured to receive the anchor bolts  76   a - c  there though. The anchor bolts extend upward and are used to securely fasten the wall section  12  against an inner track of the foundation U-channel  74  and to the worksite surface  14 . 
     Referring now to  FIG. 12  is an end view of the device  10  of  FIG. 8  with the wall section  12  positioned above the foundation U-channel  74  with bolt holes  78   a - c  of the wall section  12 . The bolt holes  78   a - c  are laterally offset from the anchor bolts  76   a - c.

The method may include aligning the anchor bolt holes  78   a - c  with the anchor bolts  76   a - c . In the view of  FIG. 13 , the wall section  12  may be laterally moved from right to left. 
     Referring now to  FIG. 9 , the method includes lowering the wall section  12  with the bottom plate  18  disposed in the foundation U-channel  74  by actuating the lifting actuator  32 . The lifting actuator  32  may be actuated to move the support frame  26  and the supported wall section  12  in a downward direction. The method may include lowering the wall section  12  with the anchor bolts  76   a - c  extending into the anchor bolt holes  78   a - c . Lastly, the method may further include tilting the wall section  12  to a vertical position by lifting the top plate off  16  of the roller pins  28   a,b  with the bottom plate  18  remaining disposed in the foundation U-channel  74 . 
     Referring now to  FIG. 14 , there is depicted an exploded perspective view of a portion of a wall lifting device  80  according to another embodiment similar to the wall lifting device  10 . Thus, similar identified structures are as described above but with those differences noted and/or depicted. In this embodiment, there is provided the wall lifting device  80  that includes a wheeled hand cart housing  82 , a support frame  84 , roller pins  86   a,b  ( 86   a  not depicted in this view), outer cylindrical elements  88   a,b  ( 88   a  not depicted in this view), a lifting actuator  90 , a housing frame  92  and a main support base  94 . In this regard, the wheeled hand cart housing  82 , the support frame  84 , the roller pins  86   a,b , the outer cylindrical elements  88   a,b , the lifting actuator  90 , the housing frame  92  and the main support base  94  are configured to perform the general functionality of respectively the wheeled hand cart housing  24 , the support frame  26 , the roller pins  28   a,b , the outer cylindrical elements  30   a,b , the lifting actuator  32 , the housing frame  34  and the main support base  36  as described above in the context of the device  10 . 
     In the embodiment of the device  80 , a support brace  96  is provided that is angularly disposed and connected to the housing frame  92  and the main support base  94 . The support brace  96  is disposed away from the support frame  84  in a plane generally perpendicular to that of the support frame  84 . It is contemplated that the main support base  94  is a generally elongate vertical element. As such, the support brace  96  is used to structurally support and securely connect the main support base  94  to the housing frame  92 . The device  80  further includes wing braces  98   a,b  ( 98   a  not depicted in this view). The wing braces  98  respectively extend laterally from the main support base  94  and connect to the housing frame  92 . Like the support brace  96 , the wing braces  98  are used to structurally support and securely connect the main support base  94  to the housing frame  92 .
