Zusammenfassung: | The present invention provides an earthquake recovery apparatus for an elevator. when a rope of an elevator has a transversal swinging motion due to an earthquake swinging motion, it is capable of preventing a damage caused by implementing a diagnosis operation from enlarging reliably. As a settlement method, in the earthquake recovery apparatus, capable of automatically implementing a diagnosis operation after an earthquake and recovering the elevator as a normal operation when there is non abnormity in the automatic diagnosis operation, has a rope transversal swinging motion detection device (long-period oscillation detector (10) ) for detecting a transversal swinging motion amount of the rope when the elevator is used. Further, according to the detection result of the rope transversal swinging motion detection device, the motion of the automatic diagnosis operation is altered. For example, when a presetting level rope transversal swinging motion amount is detected by the rope transversal swinging motion de |
