| Abstract: |
A simple and versatile knock-down scaffold structure is provided, complete in itself, supported on four normally inert corner wheels, and capable, through adjustment and/or substitution of parts, to be varied in length, width and/or height, is modified by the optional addition of a power driving and steering unit comprising a fifth wheel and a reversible, variable speed driving motor therefor, through which the scaffold may be driven forward or backward, being desirably steered and controlled as to speed and direction by a workman on the scaffold. The power driving and steering unit may be varied in height to accommodate whatever variations of height are available in the conventional scaffold structure. It may also be varied in ground pressure to increase the driving traction as desired.
