Passenger conveyor chain wear detection device and passenger conveyor chain wear detection method

摘要

PROBLEM TO BE SOLVED: To provide a wear detecting device and a wear detecting method capable of detecting local wear of a chain of a passenger conveyor. An actuator 31 is provided on a rotation track C of a plurality of links 23a, 23c, 23e that rotate while moving while meshing with a sprocket 13. The actuator 31 sequentially contacts each of the plurality of links 23a, 23c, and 23e that rotate while moving while meshing with the sprocket 13. By detecting that the displacement of the actuator 31 is larger than a predetermined reference displacement amount, wear of a portion in contact with the actuator 31 at the time of the detection is detected.
