Abstract

One embodiment of the present invention provides a multi-use move, lift, and support device. The device is made of a step ladder frame containing a plurality of steps and a hand truck frame, At least one hinge pivotally connects the step ladder frame to the hand truck frame, An anti-wobble hook may be used to lock the frames in a step ladder configuration. The hook is moved in position by the force of gravity.
