To provide an over-winding detecting weight capable of being arranged around a hanging rope suspended from a crane jib or being removed by a simple work.SOLUTION: An over-winding detecting weight comprises a weight body 40, a detachable member 50 and a fastener. The weight body 40 has an inner circumferential face 41 surrounding partially a hanging rope, and a pair of end faces 45 sandwiching a rope passage-allowable space 75. The detachable member 50 has a pair of opposing side faces 55 capable of facing the pair of end faces 45 respectively, and is attached to and detached from the weight body 40 so as to close the rope passage-allowable space 75. The opposing side face 55 has a detachable side unevenness part 54 and the end face 45 has a body side unevenness part 44 to fit into the detachable side unevenness part 54 in the fitting direction. The weight body 40 includes a supporting face 44a and prevents the detachable member 50 from falling off from the weight body 40 because the supporting face 44a abuts to a downward supported face 54a included in the detachable member 50. A fastener mutually fastens a fastened part 46 of the weight body 40 and a fastened part of the detachable member 50 at the off-position from the supported face 54a and from the supporting face 44a.SELECTED DRAWING: Figure 12
【課題】クレーンのジブから垂下した吊り荷ロープの周囲に簡単な作業で配置され、また取り外されることが可能な過巻検出用重錘を提供する。【解決手段】過巻検出用重錘は、重錘本体40と、着脱部材50と、締結具と、を備える。重錘本体40は、前記吊り荷ロープを部分的に囲む内周面41と、ロープ通過許容空間75を挟む一対の端面45と、を有する。着脱部材50は、端面45にそれぞれ対向可能な一対の対向側面55を有し、ロープ通過許容空間75を塞ぐように重錘本体40に着脱される。対向側面55は着脱側凹凸部54を有し、端面45は着脱側凹凸部54と嵌合方向に嵌合する本体側凹凸部44を有する。重錘本体40は、支持面44aを含み、支持面44aは着脱部材50に含まれる下向きの被支持面54aに当接して重錘本体40からの着脱部材50の脱落を阻止する。締結具は、被支持面54a及び支持面44aから外れた位置で重錘本体40の被締結部46と着脱部材50の被締結部を相互に締結する。【選択図】図12
