And a spreader with a self-propelled device that can be laterally self-propelled from the spreader main body into the storage rack shelves of the rack row from above the spreader main body. It was equipped with a container joint part that can be moved up and down.

[0009] Further, the container three-dimensional storage rack section is constituted by a row of container three-dimensional storage racks that are arranged opposite to each other across a passageway for a transportation means such as a container trailer, and both sides of the container hoisting club are oppositely arranged. The container three-dimensional storage rack row is movably provided above the passage passage over the track provided along the rack row so that the spreader main body and each of the storage rack shelves can be aligned with each other. The spreader self-propelled orbits are fixedly arranged in the lateral direction, and the spreader with the self-propelled device is configured to self-propelled on these spreader self-propelled orbits.

Further, the spreader body and the spreader with a self-propelled device are constructed in an extendable frame structure whose length is adjustable.

Further, an auxiliary track is provided on the spreader main body, the auxiliary track being automatically driven between the spreader self-propelled track on the spreader main body and the spreader self-propelled track in the storage rack shelf. .

Therefore, according to the present invention having the above-mentioned structure, for example, after a container unloaded from a container ship by a container crane is loaded on a transportation means such as a trailer, the trailer or the like travels along a guide line to move to a warehouse section. When a container is transported into a predetermined passageway and temporarily stopped on this passageway, a container spreader (spreader body and spreader with a self-propelled device) equipped on a ceiling traveling type container hoisting club is used to lift the stopped trailer, etc. The container is directly picked up and laterally transported and stored in the storage rack shelf of the container three-dimensional storage rack row facing the passageway.

At this time, a plurality of trailers and the like can be stopped forward and backward in the long passageway in the warehouse, and if there is a margin, the trailers and the like can be stopped near a predetermined storage address. Therefore, the spreader can be transported in the shortest distance from the trailer to the storage rack shelf by the container hoisting club, or from the storage rack shelf to the trailer in a shortest distance. The storage / delivery transfer cycle time is shortened and accelerated.

Further, by stopping the trailer or the like at the nearest position on the passageway corresponding to the storage address, two overhead traveling type container hoisting clubs are installed at the front and rear of the same track to buffer each other. It can be used without any. In this case, since the traveling track can be shared, the warehouse volume does not decrease and only the loading / unloading transportation cycle is effectively shortened.

Further, by constructing the retractable frame structure whose length can be adjusted as described above, it is possible to accommodate loading and unloading of containers of different sizes. Further, by providing the auxiliary track as described above, it is possible to make a large gap between the spreader main body portion and the container three-dimensional storage rack row.
