PROBLEM TO BE SOLVED: To achieve more adequate material storage efficiency by dividing a storage shelf for allowing the switch of a material. SOLUTION: The storage shelf LK is divided into a plurality of sections. In order to transfer the material M stored in one of two selective sections of the plurality of sections to the other section, a truck CR is moved to a reference position in one section. The material M stored in one section is temporarily loaded on the truck CR by using a crane device 11 and moved to the other section. On its way, when a reference position in the other section is detected, the truck CR is stopped and the material M is transferred to the reference position in the other section by using the crane device 11.
