To provide a crossing rod breakage detection device capable of detecting the breakage of a crossing rod even though it is a weight-less type railway crossing gate.SOLUTION: A crossing rod breakage detection device 10 detects the breakage of a crossing rod in a weight-less type railway crossing gate which lifts a crossing rod 4 by a driving force of a motor 2 and lowers the crossing rod by its own weight. The crossing rod breakage detection device 10 measures a regenerative current of the motor 2 when the crossing rod 4 is lowered by its own weight and detects the breakage of the crossing rod by comparing the measured value and a value for determination of the regenerative current.SELECTED DRAWING: Figure 1
【課題】ウェイトレス式しゃ断機であっても、しゃ断かんの折損を検知できるしゃ断かん折損検知装置を提供する。【解決手段】しゃ断かん折損検知装置10は、しゃ断かん4をモータ2の駆動力で上昇させ、自重で下降させるウェイトレス式しゃ断機におけるしゃ断かんの折損を検知する。このしゃ断かん折損検知装置10は、しゃ断かん4が自重降下するときにモータ2の回生電流を測定し、この測定値と回生電流の判定用の値とを比較してしゃ断かんの折損を検知する。【選択図】図1
