PROBLEM TO BE SOLVED: To provide an elevator balance weight clearance measurement device capable of preventing an excessive burden by the interference between an elevator installation instrument and a balance weight clearance measurement device in advance upon the occurrence of unexpected circumstances.SOLUTION: A balance weight clearance measurement device for measuring a distance between a buffer 30 installed below a lifting route of a balance weight 2 at the bottom in a hoistway of an elevator and the balance weight 2 at the lowest position of the lifting route includes: a telescopic rod part 41 attached protruding upward from the upper end of the buffer 30 capable of being expanded and contracted within a range of the longest state and the shortest state, and maintaining the length after the expansion or the contraction; and retracting means for moving the lower end of the telescopic rod part 41 below the upper end of the buffer 30 when downward force greater than a predetermined reference is applied to the telescopic rod part 41 in the shortest state.SELECTED DRAWING: Figure 2
【課題】想定外の事情の発生時であっても、エレベータ設置機器と釣合い重りクリアランス測定装置とが互いに干渉し過度な負荷がかかることを未然に防止可能なエレベータの釣合い重りクリアランス測定装置を提供する。【解決手段】エレベータの昇降路内の底部における釣合い重り2の昇降経路の下方に設置される緩衝器30と、前記昇降経路の最低位置にある釣合い重り2との距離を測定するための釣合い重りクリアランス測定装置において、緩衝器30の上端部から上方に突出して取り付けられ、最長状態と最短状態の範囲内で伸縮自在かつ伸縮後の長さを保持可能な伸縮棒部41と、前記最短状態の伸縮棒部41に予め定められた基準以上の下向きの力が作用した場合に、伸縮棒部41の下端部を緩衝器30の上端部よりも下方に移動させる退避手段と、を備える。【選択図】図2
