ABSTRACT:
Equipment for reducing vibrations of a lift cage guided at rails comprises a plurality of guide elements for guiding the lift cage along the rails, a sensor for detecting positional changes of the lift cage and/or of accelerations occurring at the lift cage, an actuator arranged between the lift cage and the guide elements and a regulating device which, on the basis of the values transmitted by the sensor, controls the actuator for changing the position of the cage relative to the rails. The regulating device has an amplification which is variable in dependence on the vertical speed of the lift cage. The amplification of the regulating device is continuously raised after activation of the regulating device and continuously lowered after switching-off of the regulating device.
