US 2024/0140509 A1 · COMBINATION MANUAL HAND TRUCK & ELECTRIC MOVER

Abstract

The inventive concept relates to a manually operated hand truck that can also be electrically powered, the apparatus referred to as an “electric mover.” The electric mover includes a main frame comprising handle bars, upper and lower load stabilizers, and a load plate connected to the main frame. In powered operation, a pair of co-axial drive wheels, positioned at the lower extremity of the main frame, is driven by a transaxle. The transaxle receives power through a control box containing a pair of replaceable batteries. The electric mover is further constructed with a positionable leg assembly comprising two moveable legs, each having a bottommost caster wheel. The moveable legs may be pivotally arranged at either an extended working position, or a stowed position against the frame, which provides an alternative load bearing configuration. Additional components include a customized fork extensions assembly and a rolling wheel attachment.
