2. Description of the Related Art FIG. 15 is a side view of a conventional cargo handling facility of a container terminal. The containers 13 loaded on the container ship 7 are unloaded by the quay container crane 8, placed on the container conveyor 11, and sent to the land side. At the land-side end, the container 13 is lifted by the yard bridge crane 9 and is loaded on the chassis (trailer) 14 or is loaded on the container yard 10. In addition,
12 is a quay.

The containers 13 stacked by the yard bridge crane 9 are sequentially transported outside from the container terminal. At this time, there is no problem if the containers 13 stacked on the upper side are sequentially transported, but if the containers 13 stacked on the lower side are to be shipped first, remove the container on the upper side. Therefore, it has to be shipped, which takes time and troubles the smoothness of the cargo handling work.
In order to solve such a problem, it has been studied to arrange storage shelves in which storage cells for storing containers one by one are formed in multiple stages so that the container 13 can be taken out from any storage cell when shipping. The present applicant has filed a patent application (Japanese Patent Application No. 8-69634 (not disclosed)) for a stack crane used in such a container terminal.

The bogie traveling rail is a seaside rail provided on the seaside away from the storage building, a building side rail provided between the seaside rail and the storage building, and a bogie provided orthogonal to both rails. Consists of rails for changing routes that are
Transfer of containers between the trolley and the container crane is performed on the seaside rail, and transfer of the container between the trolley and the seaside transfer crane is performed on the building side rail. It has traveling wheels and can travel and traverse, and the transfer of containers between the bogie and the traverser is performed by a seaside transfer crane. Here, the term “traversing” refers to a movement in a direction perpendicular to the quay, and the term “traveling” refers to a movement parallel to the quay.

It is preferable to provide a passage for the container transport chassis between the sea side end of the traverser traverse rail and the trolley building side rail.

The seaside rail and the building side rail are provided with one or two or more lanes, and the rails for changing the route are preferably provided at both ends of the seaside rail and the building side rail and in the middle part.

If the carriage traveling rail is of an elevated type, when the container is transported between the container crane and the carriage or between the carriage and the upper traverser, the vertical distance of the container can be reduced.

The sea-side transfer crane places the received container on a traverser waiting outside the storage building. The traverser traverses inside the storage building and hands it over to a stack crane waiting at the intended container storage shelf, thereby storing the container in the container storage shelf.

When shipping the containers stored in the container storage shelves on the chassis, the containers are pulled out by the stack crane and placed on the traverser. The traverser moves to the land side and moves to the outside of the storage building. Containers are loaded from the traverser to the chassis and shipped outside using a land transfer crane provided on the land side of the storage building. Since two stack cranes are provided in each row, the warehousing operation and the warehousing operation can be performed simultaneously. Further, if the passage of the chassis is provided also on the sea side of the storage building, it is possible to simultaneously unload from both the sea side and the land side when there is no cargo handling of the container ship.
