  • Braking device with automatic releasability in all operating situations
    Patent number: 11873194
    Abstract: A braking device for an elevator with a rail-guided car, which encompasses a guide rail and holds a braking element in position on one side of the guide rail and holds another braking element in position on the opposite side of the guide rail, wherein at least one of the braking elements is held in its standby position by a switchable retaining magnet against the force of an automatic actuator. The braking element is automatically driven in between the basic body and the guide rail, if the car moves at the point in time at which the braking element abuts against the guide rail. The retaining magnet is equipped with an air gap reducing agent, which reduces or eliminates an air gap between the retaining magnet and the braking element such that the retaining magnet keeps the braking element magnetically trapped again, as soon as it is switched accordingly.
