More Information
Summary:An exemplary device for use in an elevator system includes at least one friction member that is selectively moveable into a damping position in which the friction member is useful to damp movement of an elevator car associated with the device. A solenoid actuator has an armature that is situated for vertical movement. The armature moves upward when the solenoid is energized to move the friction member into the damping position. The armature mass urges the armature in a downward vertical direction causing the friction member to move out of the damping position when the solenoid is not energized.
