[0002]

2. Description of the Related Art In a conventional cargo handling facility of a container terminal, containers loaded on a container ship are unloaded and loaded by a container crane installed on a quay, sent on a trailer or a self-propelled truck, and sent to the land side. . On the land side, the container is lifted by a bridge-type crane for yards or the like and is stacked and stacked in a container yard, or is directly carried out by a trailer.

[0003] Containers stacked in a container yard are sequentially transported outside from a container terminal.

[0004]

However, there is no problem if the containers stacked in the container yard are sequentially transported from the container stacked on the upper side, but the container stacked on the lower side is not problematic. If the user wants to leave the warehouse first, it is necessary to remove the container therefrom before leaving the warehouse, which takes time and troubles the smoothness of the loading / unloading operation.

The present invention has been devised in view of such problems of the prior art, and a container is lifted from a self-propelled carriage or the like by an overhead crane between a container yard and a loading / unloading side of each container storage cell, and the container is placed on a bed. To the pallets arranged in the container, and to the container storage cells, the pallets on which the containers are placed are traversed together with the containers by the carts traversing the container storage cells on each floor, and one pallet is stored in each container storage cell. It is an object of the present invention to provide a three-dimensional container storage device in which containers are stored one by one so as to improve the smoothness and efficiency of loading and unloading operations of containers.
