Abstract
A movable pedestal scaffold having two sets of wheels on the scaffold base to permit the scaffold to be rolled horizontally while the mast of the scaffold is in a vertical position. A transport frame is mounted for vertical movement on the mast, with such movement being powered by a hydraulic cylinder. A first set of wheels is mounted on the transport frame to support the scaffold at (1) a tilted position relatively near to vertical when the transport frame is close to the base member, and (2) at a tilted position substantially inclined from vertical when the transport frame is away from the base member. A second set of wheels is mounted on the transport frame closer to the mast and to the base frame then the first set of wheels on the transport frame, the first and second sets of wheels on the transport frame acting together to support the scaffold on an elevated horizontal surface as the scaffold is raise to or lowered from that surface.
