Elevator vibration reducing device, has control portion with detection signal comparing portion for comparing detection value obtained from vibration detection signal with previously set value

摘要

The device has a vibration sensor for detecting horizontal vibration of a cage, and an actuator (13) for displacing the cage horizontally. A control portion has a computing portion (22) for computing a vibration reduction control signal. The control portion has a detection signal comparing portion for comparing a detection value obtained from the vibration detection signal with a previously set value.
