Title: Container terminal
Inventor: KAWASE AKIRA
IPC: B61B13/00
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To reduce the whole cost by dividing the storage place of containers into an import area and an export area, and handling the former by a three- dimensional storage device while the latter by a stacking device. SOLUTION: A device 50 for three-dimensionally storing containers which can be arbitrally taken out for the import use, and an inexpensive container stacking and storing device 60 is used for export containers. With the parallel arrangement of the devices 50, 60, the whole cost of container terminal can be reduced without decreasing the smoothness in the container loading/unloading operation and high efficient characteristics. Since the lateral movement of containers in the devices 50, 60 are carried out by a traverser 40, the high speed and high efficient operation of loading and unloading containers are attained more than the case where a stacker crane 3 or ceiling crane 29 is always laterally operated. Since the container terminal uses the stacking and the storing device for export containers which can be subjected to lot management, the cost reduction is ensured without decreasing the smoothness of operation.
