Document Type and Number:
WIPO Patent Application WO/2007/029331

Abstract:
A vibration reducing device for an elevator, in which an actuator for generating vibration damping force acting on an elevator car is placed in parallel to a spring for urging a guide roller to a guide rail. The actuator is controlled by a controller. The controller obtains the vibration damping force that the controller causes the actuator to produce, and the force is obtained based on information from both a car frame acceleration sensor for detecting horizontal acceleration of a car frame and a car room acceleration sensor for detecting horizontal acceleration of a car room.
