The shuttle car type storage system, which combines the traditional shelves with high-precision rails, can allow the shuttle car to run smoothly on the top. The rails also undertake the functions of cargo transportation and cargo storage, thus greatly improving the utilization rate of storage space. The shuttle truck type storage system was invented by Sweden EAB Company. Because the forklift does not need to drive into the rack to access goods, but is completed by the shuttle truck, the elimination of the forklift passage can achieve very high space utilization.
