Patent ID: 8336654

Claim:
A power device for a pallet truck, said power device comprising: (a) a main housing comprising a first friction wheel disposed on a first side of the main housing and a second friction wheel disposed on a second side of the main housing, wherein the main housing has a first flat plate disposed between the first and second friction wheels, wherein the first flat plate of the main housing is adaptable to be flushed with a second flat plate that is disposed between two front wheels of the pallet truck, wherein the main housing is temporarily attached to the pallet truck via a clamp that clamps the first flat late and the second flat together, wherein when the main housing is temporarily attached to the pallet truck the first friction wheel and the second friction wheel contact the two front wheels of the pallet truck; (b) a motor housing comprising a motor, wherein the motor is operatively connected to both the first friction wheel and the second friction wheel and to a power source, wherein the motor is for rotating both the first friction wheel and the second friction wheel, wherein the friction wheels have two operation modes, a rotation mode and a lack of rotation mode; (c) a power switch for turning on and off the power device, wherein the power switch is operatively connected to the motor; wherein rotation of the friction wheels translates into movement of the front wheels of the pallet truck, wherein lack of rotation of the friction wheels translates into reduction of rotation of the front wheels of the pallet truck.
