ABSTRACT:
A portable scaffold moving device for connecting to scaffolding and which provides rotary motion to a drive wheel, to move scaffolding in select directions. The portable scaffold moving device includes a power wheel, rotary driven through a perpendicular or right-angled gear reduction, receiving its rotary force from a drive shaft, and the drive shaft couples with a portable drill, which furnishes the rotational force necessary for driving the drive shaft, and its associated drive wheel. The bracket mechanism supporting the portable drill supports the drill during its delivery of rotary force to the drive shaft, and its wheel, and likewise, pivotally mounts to an outer support sleeve or tube that furnishes steering, to the drive mechanism, and consequentially to the scaffolding, during its power movement.
