Pallet jacks feature forks that slip underneath or into apertures on pallets, skids, and containers, and they are lifted by a hydraulic pump. These wheeled vehicles, also known as pallet trucks, pallet pumps, and pump trucks, are used in warehouses, loading docks, manufacturing plants, and other industrial settings to raise and move huge cargo. Pallet jacks are less expensive to operate and can fit into tighter places than forklifts. Pallet jacks that are operated entirely by hand require less maintenance than pallet jacks that are partially powered or fully powered. Powered pallet jacks and manual-lift/powered-drive pallet jacks are powered by an electric motor and require less physical effort to operate than manual pallet jacks.
