[0002]

2. Description of the Related Art In the conventional scaffolding, a member with a weight and size that can be handled manually by a specially skilled worker called a Toba-to is carried into an unstable place without a scaffolding, and assembled on site according to the following procedure. .. That is, a suspension rack is constructed by connecting the pipes manually loaded to the scaffolding installation place in a grid using pipe clamps, and the scaffold plates manually loaded are placed side by side on the suspension rack, and the scaffold plates are rubber. It is a procedure to fix it to the hanging rack with a band or a wire, and these are a huge number of members that are mounted and combined one by one under dangerous conditions.
Furthermore, it was constructed in such a way that the items were disassembled one by one in the reverse procedure.

[0003]

However, the work of manually loading each member into the place where the scaffold is installed and assembling it in an unstable place is a dangerous and inefficient work even for a special skill person, and the members need to be manually operated. There is a high risk of slipping from the ground or the fall of workers, and there is always a risk of death or injury. Especially, in recent years, due to the aging of special skill workers such as eagle workers and the difficulty of securing special skill workers, the risk rate increases and personal injury tends to occur frequently.
