Description

A new earthquake recovery system for the elevator has been developed and started the service. This system automatically diagnoses the halted elevator by the earthquake emergency operation, and then it tries to recover the operation normally if it doesn't detect any malfunctions. When a big earthquake occurs, many elevators have to stop their services until maintenance worker's check. It causes a long waiting time for the normal operation. The developed system can check the elevator condition by itself within about 30 minutes. Therefore it improves the user's availability by the quick recovery after the occurrence of earthquake.
