Abstract: A lightweight movable work platform includes two pairs of side rails, each side rail having a top end and a bottom end, hinge means connecting each side rail in one of the pairs of side rails in the proximity of its top end to a corresponding side rail in the other of the pairs of side rails in the proximity of its top end, wheel means connecting each side rail in said pairs of side rails at its bottom end, a plurality of spreaders, each of which connects each side rail in the pairs of side rails between its top end and its bottom end, and drive means operable in the proximity of the bottom ends of the side rails for driving the wheel means. The hinge means is operable from a closed position in which the pairs of side rails are stowed together to an open position in which the bottom ends of such pairs of side rails are spread apart in a self-supporting, working position.
