Under the environment, an automatic stereoscopic warehouse is developed, and the automatic stereoscopic warehouse is a warehouse which uses a high-rise stereoscopic goods shelf to store materials and uses a computer to automatically control a tunnel stacker to store and take the materials. Tunnel stackers are special cranes developed along with the advent of automated stereoscopic warehouses, commonly referred to as stackers for short, and are the most important lifting and transporting equipment in automated stereoscopic warehouses. The stacker runs along the track in the tunnel of the automatic stereoscopic warehouse, stores the materials at the tunnel mouth into the appointed goods lattice of the stereoscopic goods shelf, or takes out the materials in the appointed goods lattice and conveys the materials to the tunnel mouth, so as to finish the warehouse-in and warehouse-out operation of the materials, thereby not only reducing the labor cost, but also improving the safety of product storage.
