Abstract
An elevator installation braking device is actuated and reset by an electromechanical actuator including an energy store, a retaining device, a resetting device and at least one connecting element for connecting the actuator to the elevator brake. The resetting device retains the connecting element, via the retaining device and counter to the action of the energy store, in a first operating position, corresponding to a standby position of the brake, or guides the actuator back into this position. The energy store acts as required, upon release of the retaining device, on the connecting element to actuate the brake and to bring it into a corresponding engagement position. The resetting device has a recoil-prevention device to relieve recoil forces. The energy store can have a stop buffer to reduce the force impact when the energy store strikes an end position.
