Abstract:

A pneumatic cylinder actuated pallet jack assembly for mechanically lifting and lower a pallet includes a pallet jack, a plurality of pneumatic cylinders, and a compressor. The forks of the pallet jack are slidably coupled to a frame of the pallet jack. Each of a pair of rear rollers that is coupled to a respective fork distal from the frame and a roller module that is slidably coupled to the frame are selectively vertically positionable. A tow bar is pivotally coupled to the frame proximate to the roller module. Pneumatic cylinders are operationally coupled singly to each of the forks, the pair of rear rollers, and to the roller module, and the compressor. The compressor is positioned to selectively actuate respective pneumatic cylinders to size a gap between the forks and to raise the forks and the frame to lift a load that is positioned on the pallet.
