To provide a hanging tool and a fall prevention method for holding and supporting an object to be lifted in a rotatable manner, which is screwed onto a bolt part of a work object and is rotated to be removed from the bolt part after work is completed.SOLUTION: A hanging jig that suspends and supports an object to be lifted, which is screwed into a bolt part 102 of a work object and rotated to be removed from the bolt part 102 after the work is completed has an inner annulus member 1 that can be attached to and detached from the object to be lifted, an outer annulus member 3 rotatably attached to the outer peripheral portion of the inner annulus member 1 with respect to the inner annulus member 1, a wire 4 whose one end 4a is fastened to the outer peripheral portion of the outer annulus member 3, and holding means 5 for holding the other end 4b of the wire 4. When the object to be lifted is removed from the bolt part 102, the object to be lifted is suspended and supported via the outer annulus member 3 and the inner annulus member 1 by the wire 4 whose other end 4b is held by the holding means 5.SELECTED DRAWING: Figure 1
【課題】作業対象物のボルト部に螺合され作業終了後に回転されてボルト部から外される吊上げ対象物を回転可能に保持して吊下げ支持する吊り下げ治具及び落下防止方法を提供すること。【解決手段】作業対象物のボルト部102に螺合され作業終了後に回転されてボルト部102から外される吊上げ対象物を吊下げ支持する吊り下げ治具であって、吊上げ対象物に着脱可能に取付けられる内周円環部材1と、内周円環部材1の外周部に、内周円環部材1に対して回転可能に取付けられている外周円環部材3と、外周円環部材3の外周部に一端部4aが締結されたワイヤ4と、ワイヤ4の他端部4bを保持する保持手段5とを有し、ボルト部102から吊上げ対象物が外されたときに、保持手段5により他端部4bを保持されたワイヤ4により、外周円環部材3及び内周円環部材1を介して吊上げ対象物を吊下げ支持することを特徴とする吊り下げ治具。【選択図】図1
