To provide an elevating body derailment detection device that can suppress a decline in work efficiency of maintenance personnel.SOLUTION: An elevating body derailment detection device includes a wire 8, a suspension member 9, a detection circuit 14, an arm, and a detection unit 24a. The wire 8 is arranged in parallel with an elevating direction of an elevating body. The suspension member 9 is provided at one end of the wire 8, and is provided with a first conductive part. The detection circuit 14 includes second conductive parts 20a, b that are electrically connected to a first conductor part 19, and a current flows through the first conductive part 19. The arm is arranged on the elevating body, has a hollow part through which the wire 8 is to be passed in parallel with the elevating direction. When the elevating body derails from the guide rail, the hollow part contacts the wires 8 to move the suspension member 9 so as to electrically disconnect the first conductor part 19 from the second conductor parts 20a, b. When the first conductor part 19 is electrically disconnected from the second conductor parts 20a, b, the detection unit 24a detects that the elevating body has derailed from the guide rail.SELECTED DRAWING: Figure 2
【課題】保守員の作業効率の低下を抑制することができる昇降体の脱レール検出装置を得る。【解決手段】昇降体の脱レール検出装置は、ワイヤ8、吊下部材9、検出回路14、腕部及び検出部24aを備える。ワイヤ8は、昇降体の昇降方向と平行に配置される。吊下部材9は、ワイヤ8の一端に設けられ、第1の導体部が設けられる。検出回路14は、第1の導体部19に電気的に接続する第2の導体部20a、bを有し、第1の導体部19を介して電流が流れる。腕部は、昇降体に設けられ、昇降方向と平行にワイヤ8を通す中空部を有し、昇降体がガイドレールから外れたとき当該中空部がワイヤ8に接触して吊下部材9を移動させ、第1の導体部19と第2の導体部20a、bとを電気的に非接続にする。検出部24aは、第1の導体部19と第2の導体部20a、bとが電気的に非接続のとき、昇降体がガイドレールから外れたことを検出する。【選択図】図2
