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 and maneuver it easily. Pallet jacks are commonly found in warehouses, retail stores, and shipping facilities. These tools come in various designs, including manual pallet jacks that require physical effort to operate and electric pallet jacks that use a motor for lifting and moving. They are essential for improving efficiency in material handling and reducing the risk of injury from lifting heavy loads.
