A hand truck or cart has a frame with telescopic segments and wheels mounted to a lower end of the frame for maneuvering the frame on a support surface. The frame has an extended position for operational use and a collapsed position for storage purposes. When the frame is in the collapsed position, it has a vertical height that is only a fraction of its height when in the extended position. Each of the telescopic arms have locking elements for securing the frame in the extended position. The cart also has pivotable support and fork platform for supporting the loads. The support platform can be raised and lowered along the length of the frame with a winch assembly that is mounted to the frame. The cart is also provided with a pair of supplemental support legs for providing additional support for the frame.
