A pallet jack is a manual or powered device used to lift and move pallets, which are flat structures used for storing and transporting goods. It typically features two forks that slide under the pallet, allowing the operator to lift it off the ground. Pallet jacks are commonly found in warehouses and retail environments, making it easier to handle heavy loads without the need for a forklift. The operation of a pallet jack is straightforward. The user pumps a handle to raise the forks, and then they can maneuver the loaded pallet to its desired location. This tool is essential for improving efficiency in material handling and reducing the risk of injury associated with lifting heavy items manually.
