A gate type that is arranged so as to be able to traverse along the rails, is capable of delivering containers between the sea-side transport truck and the land-side transport truck, and is capable of stacking and arranging containers at required positions between the yard traverse rails in a plurality of stages. And a transfer crane.

According to the above means, the following effects can be obtained.

When unloading a container loaded on a container ship, the container loaded on the container ship is lifted by a container crane, transferred to a sea-side transfer cart, and then the sea-side transfer cart is removed from the container. Move along the shortest route to the desired row position of the container yard to be stored by circulating on the seaside running rail and on the seaside traversing rail, and move to the desired row position of the container yard. In step (1), a container on the sea-side transport trolley is lifted by a transfer crane, the transfer crane is traversed along a yard traversing rail, and the containers are stacked in a desired horizontal position in a desired row of the container yard.

When unloading the containers stacked in the container yard, the stacked containers are lifted by a transfer crane, and then the transfer crane is traversed along the yard traverse rail toward the land-side traverse rail. The container is placed on a land-side transport vehicle waiting on the land-side lateral rail, and the land-side transport vehicle on which the container is mounted is circulated from the land-side lateral rail to the land-side travel rail. To stop at the position of the desired transfer machine, and the transfer machine transfers the container on the land-side transport cart onto the chassis of the trailer.

The operation of loading the containers transported by the trailer chassis into the container yard and the operation of loading the containers stacked in the container yard on the container ship are performed by operations opposite to those described above.

As a result, since the containers are stacked and stored in the container yard, there is no need to provide a three-dimensional container storage building, which leads to cost reduction and also allows the sea-side transport vehicle to be moved from the sea-side traveling rail. The sea-side traveling rail and land-side traveling rail can be moved with a large radius of curvature by making it possible to move over the sea-side traveling rail and by moving the land-side carriage from the land-side traveling rail to the land-side traveling rail. There is no need to bend, so there is no need to secure a large space outside the container yard, and the space utilization efficiency is improved.
