Abstract
A braking device may be utilized by an elevator system that has a cabin that is movable within an elevator shaft. The braking device may comprise an actuator and a brake. The actuator may be configured to provide an actuating force for the brake as needed. The braking device may include a force measuring assembly for generating a load state value of the cabin. The force measuring assembly may be mechanically coupled to the actuator such that the actuating force is dependent on the load state value. The actuator may be configured such that the greater the load state value the greater the actuating force.
