[0003] The overhead traveling crane is designed to transport an object to a target position in the work area by moving the crane on a rail mounted on the ceiling of the work area.

[0004] In addition, when an object is transported to a target position in a wide work area, there is also known an apparatus in which a rail is movable so that a crane can be moved to a predetermined position.

On the other hand, when there are a plurality of work areas in a partitioned state, rails are arranged on the ceiling of each work area, and a crane runs on each rail.

[0006] Then, the transported object is transported to the loading / unloading entrance of each work area by using an appropriate transport means, and the transported article is reloaded from the transport means to a crane in each of the work areas, and a desired position of each work area is transferred. The object to be transported is transported up to this point.

[0007]

When an object to be transported is transported to a plurality of work areas by using the above-mentioned conventional overhead traveling crane, the transport object is transported by a suitable transport means to a carry-in / out entrance of each work area. After that, the conveyed objects are transshipped to the crane installed in the work area, and then the conveyed objects are transported to the target position in the work area by the crane. There is a problem in that the conveyed objects must be transshipped to the crane in the work area, and this transposition takes time and effort, and therefore, there is a problem in that a large number of transport workers are required.

[0008] Further, if it is necessary to reload the work at the loading / unloading entrance of the work area, human labor is required, and it is difficult to automate the transfer of the work into the work area. There was a problem.
