Conventionally, this type of container handling apparatus has been constructed as shown in FIGS. 5 and 6. FIG. 5 shows a first conventional example. As shown in the figure, in the container handling apparatus a of the first conventional example, a front leg d and a rear leg e traveling and moving on a rail c provided along the quay b, and supported on the front leg d and the rear leg e. The girder f, the boom h extending from the girder f to the sea g side, and the trolley i traversing the girder f and the boom h are provided.

In the container handling apparatus a of the first conventional example as described above, one trolley i reciprocates to unload a container l from the land j onto the container ship k.

However, in this container handling device a of the first conventional example, since one trolley i reciprocates on the girder f and the boom h, it moves forward from the land j to the container ship k to load and unload the container l. After that, there was a problem that it was not possible to move to the next process without returning after returning to the original position.

In order to eliminate such problems, the second method shown in FIG. 6 is used.
The container handling device a of the conventional example is devised. As shown in the figure, the container handling device a of the second conventional example has a wharf b

A side trolley q is provided.

In the container handling apparatus a of the second conventional example as described above, when loading and unloading the container 1 from the land j onto the container ship k, it is provided at a predetermined height position from the land j by the land side trolley q. After transferring the container 1 to the relay platform o, the transferred container 1 was unloaded from the platform o on the container ship k by the sea side trolley p.

[Problems to be Solved by the Invention] Meanwhile, the container handling apparatus a of the second conventional example has the following problems.

The land side trolley q moves back and forth on the second girder n to transfer the container 1 from the land j to the relay platform o, and the sea side trolley p moves back and forth the first girder m and the boom h to transfer. In order to load and unload the prepared container 1 from the platform o to the container ship k, the land-side trolley q or the sea-side trolley p can unload the container 1 onto the platform o and immediately move to the next process. Although the problem in the conventional container handling apparatus a is solved,
The land side trolley q and the sea side trolley p may interfere with each other,
There was a problem that the safety and work efficiency decreased.

Further, if the process transition of the land side trolley q or the sea side trolley p is too early, a plurality of containers 1 must be temporarily placed on the relay platform o, and the movement of the containers l on the platform o. Because it is difficult to land q
There is a problem in that the delivery work between the sea side trolley and the sea side trolley becomes complicated and the work efficiency decreases.

In view of the above problems, it is an object of the present invention to provide a container handling apparatus that can improve work efficiency and safety.
