Abstract
An elevator system includes an elevator car, at least one elevator drive arranged in an elevator shaft and a support strap, wherein the elevator car is arranged in the elevator shaft for movement via the support strap by the elevator drive. A brake system includes a car braking unit associated with the elevator car and a drive braking unit associated with the elevator drive. The car braking unit and the drive braking unit can together be controlled from a common brake control device. The brake system can be used for new elevator system installations and for retrofitting existing elevator systems.
Claims16
An elevator system including an elevator car, an elevator drive and a support means, wherein the elevator car is moved in an elevator shaft by the elevator drive via the support means, comprising:
- a car braking unit for braking the elevator car;
- a drive braking unit for braking the elevator drive;
- and
- a brake control unit for controlling the car braking unit and the drive braking unit, wherein the brake control unit controls the car braking unit and the drive braking unit for joint actuation so that the car braking unit and the drive braking unit are actuated jointly and together as a redundantly operating brake system.
A brake system for an elevator system, the elevator system including an elevator car movable by an elevator drive, comprising:
- a car braking unit for braking the elevator car;
- a drive braking unit for braking the elevator drive;
- and
- a brake control unit connected via at least one communication interface to the car braking unit and to the drive braking unit, the brake control unit jointly controlling the car braking unit and the drive braking unit for joint actuation to operate as a redundantly operating brake system.
A method for controlling a brake system of an elevator system, the elevator system including a car braking unit for braking an elevator car and a drive braking unit for braking an elevator drive, comprising the steps of:
- providing a brake control unit in communication with the car braking unit and the drive braking unit;
- and
- operating the brake control unit to jointly control the car braking unit and the drive braking unit so that the car braking unit and the drive braking unit are actuated jointly and together as a redundantly operating brake system.
