PROBLEM TO BE SOLVED: To provide a rope separation preventing structure that is able to avoid a size increase in a width direction.SOLUTION: A crane rope separation preventing structure (10) comprises: a pair of support parts (20); a support shaft (30); a sheave (40); and a restricting member (50) that restricts separation of the rope from the sheave (40), the restricting member (50) being rotatable around a rotation center axis parallel to the support shaft (30) and being able to switch, by means of the rotation, between a restricting position where separation of the rope from the sheave (40) is restricted and a replacing position where replacement of the rope with respect to the sheave (40) is allowed; a hold member (60) that is able to selectively hold the restricting member (50) between the restricting position and the replacing position.SELECTED DRAWING: Figure 2
【課題】幅方向への大型化を回避可能なロープ外れ止め構造を提供すること。【解決手段】クレーンのロープ外れ止め構造(10)であって、一対の支持部(20)と、支軸(30)と、シーブ(40)と、ロープのシーブ(40)からの離脱を規制する規制部材(50)であって、支軸(30)と平行な回動中心軸回りに回動可能であり、その回動により、ロープのシーブ(40)からの離脱を規制する規制位置と、シーブ(40)に対するロープの掛け替えを許容する掛替位置と、を切り替え可能な規制部材(50)と、規制部材(50)を規制位置及び掛替位置に択一的に保持可能な保持部材(60)と、を備えること。【選択図】図2
