Description of the Related Art Conventionally, as an overhead traveling crane capable of transporting and hoisting materials to any place in a plurality of spans surrounded by a pillar without interfering with surrounding pillars in a building, a crane provided on a ceiling part In addition to a self-contained crane in which a traveling beam, a swing arm, a trolley, and the like are mounted on a traveling garter, there is a structure shown in FIG.

This overhead traveling crane is movable along the garter guide rails 2 arranged on the ceiling in parallel to each other and the garter guide rails 2 and 2 for each span partitioned by columns 1 established at predetermined intervals. The crane main body 3 suspended at, and the inter-span rail 4 arranged at one end of the garter guide rail 2 orthogonally to the garter guide rail 2 over the span, and moving along the inter-span rail 4, The crane main body 3 is transferred from one span to another by a transfer device 5 such as a traverser system, a turntable system, or a rail pointer system. The crane body 3 includes a crane garter and a moving trolley that moves along the crane garter. Note that FIG.
In the figure, for the sake of explanation, a case in which two sets of garter guide rails 2 are arranged is shown.

In this overhead traveling crane, the crane body 3 is moved to another span as follows. The crane main body 3 of a certain span is moved toward the transfer device 5 along the garter guide rails 2 and 2, and the crane main body 3 is remounted on the transfer device 5. After that, the transfer device 5 is moved along the inter-span rail 4, and the crane main body 3 mounted on the transfer device 5 is transferred to the garter guide rail 2 of the desired span, and further to the garter guide rail 2.

Must be done, and the overall structure becomes complicated. In addition, the crane body 3 is attached to the garter guide rail 2
Must be moved to the transfer device 5 arranged at one end of the transfer device 5, and the transfer device 5 itself must also be moved along the inter-span rail 4, resulting in a longer transport time. Further, in addition to the garter guide rails, in order to support the inter-span rails and the transfer device, the building side also needs to be made corresponding to these, which is complicated.

[0006] In addition, if the transfer device is not provided,
It is conceivable to arrange a crane body for each garter guide rail 2 of each span, but this method causes a decrease in the operating rate of each crane body, which is not economical, and because the number of crane bodies increases, It is not preferable because the weight of the whole is increased and a burden is placed on the building side.

[0007] In the case of an integrated overhead traveling crane, if the function of the overhead traveling crane is to be improved, the size of the crane body is increased,
There is a drawback that it becomes complicated and its weight becomes large.

Therefore, in the present invention, it is not necessary to provide a transfer device for transferring the crane body and the moving trolley to another garter guide rail, an inter-span rail, etc.
An object of the present invention is to provide an overhead traveling crane capable of freely moving a moving trolley required for transportation within each span and between spans.
