A battery operated stacker is a type of material handling equipment used in warehouses, factories, and other industrial settings to lift and move pallets and other heavy items. It is powered by an electric motor that runs on a rechargeable battery. The stacker typically has two forks that can be raised or lowered to lift the load and move it to a different location. Battery operated stackers is used in areas where there is limited space, as it is more compact than traditional forklifts. It is also used for tasks that require frequent lifting and moving of lighter loads.
