Abstract: A detachable lifting device can be attached to and works in conjunction with an upright portion of a hand truck. The invention allows the user to move heavier loads than would be possible with the hand truck alone, and to lift the loads to table or counter levels. The invention is formed with a preferably rectangular frame, including laterally spaced-apart lift rails. A winch assembly, lifting cable, cable winding element, and a pulley operate with the frame to slide a lifting platform upwardly and downwardly along lift rails in a space formed by a spacer attached between the hand truck and the lift rail. The platform attachment is inventively designed with a bolt, bushing, and nut assembly, wherein the bushings frictionally engage with and rotate circularly against the lift rails as the platform moves up and down them. Preferably, the invention is operated via remote control.
