Gantry crane is generally the same with overhead crane except that it is supported by legs. Instead of running along overhead runway, it can travel along rails mounted on the ground or run on wheels, allowing for the ease of movement and transportation. Warehouse gantry crane has many advantages and has been widely used in various industries.

The warehouse gantry crane produced by SEVENCRANE has an Automatic Storage and Retrieval System (ASRS), which is a warehouse stacker used for elevated shelf systems. The AS/RS lifting system uses automated technology to store and retrieve pallets. The warehouse crane system is mainly composed of three operating mechanisms: lifting mechanism, crane operating mechanism, and trolley operating mechanism.
