Abstract: During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S2_S6). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S7_S11). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S12_S14).
