Definitions

  • the present invention relates to an elevator brake with an actuating device for braking and holding an elevator car in an elevator system, a correspondingly executed Aufzugsan position and a method for reshuffling and subsequently holding an elevator brake in a standby mode.
  • the elevator system is used for the essential vertical transport of persons and goods over several floors of a building.
