Abstract (en)
[origin: EP2213606A1] In an elevator apparatus, a car is suspended by a main rope on a first side of a sheave, and a counterweight is suspended by the main rope on a second side of the sheave. A rotation detector generates a signal that corresponds to rotation of the sheave. A slippage testing portion operates the car through a round trip for a predetermined distance, and tests for slippage between the sheave and the main rope based on a difference between a signal from the rotation detector during ascent and a signal from the rotation detector during descent.
