A pallet jack, also known as a pallet truck is a tool used to lift and move pallets. Pallet jacks are the most basic form of a forklift and are intended to move pallets within a warehouse. This jack is composed of 3-stage piston rods creating light pumping while giving strong rigidity. Support legs come into operation automatically to prevent it from moving when forks are raised for safety concern. Jack automatically slows the descending speed when heavy goods are loaded to help prevent goods get damaged.
