Conventional technology Conventionally, when constructing a high-rise building, the work of hoisting steel frame building members such as columns, beams, and floor materials above is generally performed by installing a jib crane with a high lift at a high place and wire the building members. It is hung with a rope and transported to the intended installation location.

By the way, as a method of constructing a high-rise building, first assemble a working floor with jacks on the legs, then sequentially assemble the lower buildings by interposing pillar materials between the ground and the jack, and ascend the working floor to construct a high-rise building. Something to build is proposed.
(For example, Japanese Patent Application No. 1-226164) In such a case,
Sib cranes cannot be used, and it is necessary to suspend the building members with an overhead crane installed on the working floor and carry them to the intended place.

Problems to be Solved by the Invention However, if the conventional overhead crane is used as it is,
There is a problem that building members can not be carried outside the span of the crane traveling rail, and if jigs are used for that purpose, in order to carry pillar materials and floor materials etc. to the target location in a posture corresponding to assembly, A jig corresponding to each member is required, and the jig must be replaced for each member to be transported, which is a very complicated work.
