BACKGROUND 
       [0001]    Technical Field 
         [0002]    The embodiments herein generally relate to climbing systems, and more particularly to ladders and scaffolding systems. 
         [0003]    Description of the Related Art 
         [0004]    Equipment such as ladders or scaffolds allow for the performance of tasks at heights not normally reachable by a worker. However, when using conventional ladders or scaffolds, the worker&#39;s horizontal reach is generally limited to the worker&#39;s arms&#39; span. In order to reach a further distance, the worker may need to stop work and relocate the ladder. For example, when installing weirs or pipes at high places using a conventional ladder, workers may need to periodically stop work. Alternatively, workers may require assistance of others or may need to use other expensive tools to do the required job. It would be desirable to use systems that allow for extending the reach of the worker while on top of a ladder or a scaffold.

Wheels  1410   a,    1410   b  may be the motorized wheels and wheels  1411  may be non-motorized, in one embodiment (note in  FIG. 14 , only one wheel  1411  is shown due to the angle of the view; however the scaffold  1400  contains a pair of wheels  1411  configured on opposite ends (e.g., one at position E and one at position F). The motor box  1406  may be controlled using a joystick  1412 , which may be configured on the board  1402 . In an embodiment, the joystick  1412  is connected to the motor box  1406  using a wire  1408 . In an embodiment, the joystick  1412  is connected to the motor box  1406  wirelessly. 
         [0051]      FIG. 15 , with reference to  FIG. 14 , is a schematic diagram illustrating the adjustable tie bar  1404  (e.g., tie bars  1404   a,    1404   b  of  FIG. 14 ), according to an embodiment herein. In an embodiment, the adjustable tie bar  1404  is configured to safely hold bars  1414 ,  1416  of the scaffold  1400 . In an embodiment, the length of the adjustable tie bar  1404  may be adjusted to securely hold the bars  1414 ,  1416  at appropriate widths. 
         [0052]      FIG. 16 , with reference to  FIGS. 14 and 15 , is a front view of a scaffold  1600  according to an embodiment herein. In an embodiment, the scaffold  1600  includes boards  1602  to accommodate a user/worker  1601 . The scaffold  1600  further includes motor hub wheels  1602   a,    1602   b.  The motor hub wheels  1602   a,    1602   b  may be configured to lock-in the adjustable jacks  1604   a,    1604   b.  In an embodiment, the jacks  1604   a,    1604   b  are configured to level the scaffold  1600 . The jacks  1604   a,    1604   b  can be adjusted manually or automatically by the joystick  1612  to make the scaffold  1600  level while it is moving. The motor hub wheels  1602   a,    1602   b  may be connected to a battery/control box  1606 . In an embodiment, the battery/control box  1606  is configured to control movements of the motor hub wheels  1602   a,    1602   b  using wires  1608 . In an embodiment, the wheels  1602   a,    1602   b  have a diameter greater than approximately twelve inches, although other sizes and configurations are possible in accordance with the embodiments herein. Unlike conventional approaches where workers need to surround the entire building or structure with scaffolding, the moving scaffolds  1400 ,  1600  of  FIGS. 14 through 16  allow the workers to use one scaffold and be able to move around a building or structure. 
         [0053]    The ladders  100 ,  500 ,  1100 ,  1200 , and the scaffolds  1400 ,  1600  may be used at any location including, but not limited to, a construction site, a warehouse, a library, home, business, and a store. The ladders  100 ,  500 ,  1100 ,  1200 , and the scaffolds  1400 ,  1600  may also be used by filmmakers by placing camera equipment or the cameraman on the ladder or scaffold. The embodiments disclosed herein may be used to save production time. 
         [0054]    All dimensions mentioned herein are only exemplary and for illustration purposes. It is obvious to a person with ordinary skill in the art that other dimensions may be used based on any specific application of the embodiments herein. The embodiments herein may be used in connection with other tools, accessories, and parts used, for example, in a construction site. 
         [0055]    The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the appended claims.
