An auto stacker is similar to a semi-auto stacker, but has a drive motor that enables auto movement, eliminating the need for manual intervention. It is powered by a drive motor and hydraulic power package that is connected to a 12V battery x 2, which can be conveniently charged using the built-in charger. The entire movement and lifting operation can be controlled by the user through the multi-function handle. The auto stacker reduces the amount of physical effort required to move and lift the load, making the job easier and safer. This feature not only enhances the productivity but also prevent work-related injuries, making it an ideal choice where there is frequent use.
