A powered hand truck 10 for assisting in the movement of objects. The powered hand truck includes an electric motor 42, a power source 46, a programable motor controller 44, and a transaxle 40, which are adaptable to existing hand trucks, or may be integrated into a new powered hand truck. The transaxle 40 includes a differential allowing easy maneuvering of the hand truck 10. Power is provided by replaceable/rechargeable batteries. The motor controller 44 controls the motor 42 to provide consistent speed independent of load weight or incline, and further provides regenerative braking. The motor controller 44 also includes diagnostics communicated through a display 56 mounted to the hand truck 10. |
