2. Description of the Related Art Conventionally, when a material such as a crane is transported by a crane, one end of a cord, such as a wire or sling, is wound around the transported object at the position where the transport is started and the other end is hooked. The work was carried out by hand, and the work for removing the cord from the hook at the transportation end position was performed manually.

Since the transported object being transported moves in the air, the work of winding the cord on the transported object and the work of hooking it on the hook at the transport start position must be performed reliably and accurately. Manual work and confirmation are required.

However, at the position where the transportation is finished,
The work of removing the cords from the hooks is carried out by the worker to the position where they are to be removed.When the transported items are large and heavy, or when long items are bundled and moved, the transported items are separated by opening. Not only is this work extremely dangerous because part of the human body may become an underlay, but also when the work site is wide and the transportation range is wide, or when the number of workers is small,
There was also the difficulty of moving up and down and left and right in the work site to the transportation end position.
