Abstract:
A scaffold comprising:a. a frame of substantial height; b. a drive shaft; c. a tube having a inner diameter slightly larger than the outer diameter of the drive shaft; d. a tool housing fixedly connected to the top of the tube, and arranged approximately at the top of the frame; e. a wheel assembly fixedly connected to the bottom of the tube, and extending at least in part below the bottom of the frame; wherein the tube rigidly mounted in a vertical orientation on said frame of substantial height, the drive shaft is oriented inside the tube such that a portion of the drive shaft extends beyond each end of the tube and the bottom end of the drive shaft, and connects to the wheel assembly, and a rotational tool is adapted to be placed in the tool housing and connected therein to the top of the drive shaft to enable the tool to transfer its forward and reverse rotational force through the drive shaft to rotate the wheel and thereby move the scaffold.
