A semi-auto battery operated stacker is similar to manual stacker, but it is equipped with an electric lifting mechanism that helps to reduce the amount of physical effort required by the users. It is powered by a hydraulic power package that is connected to a 12V battery. The battery can be recharged using the charger that is built-in to the stacker. The lifting mechanism is initiated by pressing the lift button, while the movement is controlled by the user manually. The electric lifting mechanism effectively decreases the amount of physical effort required to lift the load, making the job easier and safer.
