It is known that a building member is assembled, and when the assembly of a predetermined layer is completed, a girder unit is lifted up by a jack to carry in and assemble building materials of an upper layer.

[0003]

An overhead crane used in such a construction method is a first crane that travels along a guide rail provided in a girder unit, as shown in FIGS. 2 and 4 of JP-A-5-141092. The traveling rail, the second traveling rail traveling along the first traveling rail, and the crane traveling along the second traveling rail,
This crane is movable in two directions that are orthogonal to each other.

However, since this overhead crane travels on the first traveling rail and the second traveling rail in two directions orthogonal to each other to move the crane, the moving range of the crane, that is, the first traveling rail and the second traveling rail. No columns or the like can be provided in the traveling range of the traveling rail, and the structure of the structure is limited.

Therefore, an object of the present invention is to provide an overhead crane device which can solve the above-mentioned problems.
