According to the hoisting system of the first aspect, the swivel axis formed between the swivel arm and the fixture and the swivel axis formed between the swivel arm and the swivel rail arm are respectively provided. In addition to turning appropriately, the length of the turning arm can be freely expanded and contracted to position equipment such as containers hung on the turning rail arm for high-place work and transportation with respect to the wall surface of the building at any angle. Therefore, even if the length of the gondola in the longitudinal direction is longer than the distance between adjacent columns, it is possible to introduce a part of the container into the interior of the building. It is possible to easily carry in and out people, and it is possible to secure high lifting efficiency even on high floors.

According to the hoisting system of claim 2,
The work / transportation facility for high places such as a gondola is composed of a lifting part and a working / transportation part such as a container, and the lifting part and the container part can be easily separated by attaching and detaching the connecting member. Therefore, for example, after hoisting a gondola to a predetermined place, cut off the container part on which the material is loaded, attach another container part on which waste materials, etc. are loaded, and repeat the unloading cycle to efficiently perform lifting work. It becomes possible to do.

According to the hoisting system of claim 3,
Since the swivel rail arm is configured to be extendable and contractible, it is possible to introduce the gondola further into the building by extending the swivel rail arm after introducing a part of the gondola into the building. It becomes possible to carry out the carry-in / carry-out work of.

As in the lifting system according to claim 4,
By adopting a configuration in which the work / transportation part such as a container is hung on the extendable part of the extendable swivel rail arm, the swivel arm length, the swivel angle of the swivel axis, and the swivel angle of the swivel axis of the swivel rail arm are adopted. Can be adjusted appropriately, the swivel rail arm can be further extended, and the gondola can be loaded into the building, and then the work / transportation part such as the container can be easily removed and transported to a predetermined site.

Further, as in the lifting system according to the fifth aspect, a construction is adopted in which a work / transportation part such as a container is suspended via a trolley which is movable along the longitudinal direction of a telescopic swing rail arm. The swing arm length,
Adjust the turning angle of the turning axis and the turning angle of the turning axis of the turning rail arm appropriately, further extend the turning rail arm and carry the gondola into the building, then move the trolley to the tip of the turning rail arm. By removing the work / transportation part such as the container from the trolley,
It becomes possible to easily transport materials and the like to a predetermined site.

Further, according to the hoisting system of the sixth aspect, depending on the angle of the turning rail arm with respect to the wall surface of the building, the extension / contraction length of each turning arm and the turning axis of each turning arm can be adjusted. Since it is possible to automatically adjust the turning angle and the turning angle of the turning axis of the turning rail arm, materials can be automatically lifted regardless of the column spacing of the building where the materials are loaded and unloaded. However, by constructing an automatic system that can automatically load the gondola into the building, it is possible to significantly reduce the labor required for lifting work on high floors.
