To early restore an elevator apparatus.SOLUTION: A monitor according to the present embodiment comprises a movable body to move up and down along a rail in a hoistway, a sensor installed in the movable body and to detect the horizontal acceleration of the movable body stopped by an earthquake, computing means to compute the acting force on the rail based on the detecting result by the sensor, and determination means to determine that the diagnostic operation is possible to diagnose an abnormality by moving up and down the movable body when the acting force is less than or equal to the threshold representing the resistance limit of the rail and to determine that the diagnostic operation is impossible when the acting force exceeds the threshold.SELECTED DRAWING: Figure 2
【課題】エレベータ装置を早期に復旧する。【解決手段】本実施形態に係る監視装置は、昇降路を、レールに沿って昇降する移動体と、移動体に設けられ、地震によって停止した移動体の水平方向の加速度を検出するセンサと、センサの検出結果に基づいて、レールに作用する作用力を演算する演算手段と、作用力が、レールの耐力限界を示す閾値以下の場合には、移動体を昇降させて異常診断を行う診断運転が可能であると判断し、作用力が、閾値を超えた場合には、診断運転が不可能であると判断する判断手段と、を備える。【選択図】図2
