Title: ELEVATOR MOVEMENT DISTANCE MEASURING DEVICE AND ELEVATOR MOVEMENT DISTANCE MEASURING METHOD
Abstract:
An elevator movement distance measuring device (1) comprises: a first sensor (31a) that detects the amount of movement of a main rope that moves faster than a car with the movement of the car; a first movement distance computing unit (32a) that calculates, as a first movement distance, the movement distance of the main rope moving faster than the car using the amount of movement detected by the first sensor; and a car movement distance computing unit (33) that calculates the movement distance of the car using a roping ratio and the first movement distance.
