[0005] However, in the opposite case, that is, when the car is fully loaded, the maximum braking force acts on the car later, so the braking distance of the fully loaded car is longer

Embodiment Construction

[0025] figure 1 An elevator installation 1 according to the invention is shown having a car 2 accommodated in an elevator shaft 3 . The car 2 can move vertically based on the guide rail 4 by means of not shown guide wheels. The elevator installation 1 also includes a braking device 5 with at least one brake 6 . In the event of a fault, one or more such brakes 6 can be activated. The braking device 5 includes a manipulator 7 which provides braking force when necessary. The braking force is transmitted to the brake 6 through the connector 8 .

[0026] figure 2 The braking device 5 is shown in more detail. Accordingly, the braking device comprises three basic components, namely the brake 6 , the manipulator 7 and the force sensor assembly 18 .

[0027] The brake 6 interacts with the guide rail 4 during maneuvering, thereby at least reducing the speed of the car 2, in particular bringing the car to a stop. The manipulator 7 operates the brake 6 . In this case, the manipul...

Abstract

The invention relates to braking device (5) for an elevator system (1). The elevator system (1) comprises a cab (2), which can be moved within an elevator shaft (3). The braking device (5) has an actuator (7) and a brake (6). The actuator (7) is designed to provide an actuation force (B) for the brake (6) as needed. The braking device (5) has a force-measuring assembly (18) for producing a load state value (p20) of the cab (2). The force-measuring assembly (18) is mechanically coupled to the actuator (7) in such a way that the actuation force (B) depends on the load state value (p20).

Description

technical field [0001] The invention relates to a braking device for an elevator installation, an elevator installation and a method for adjusting an actuating force of a braking device. Background technique [0002] In conventional cable elevators, the fall of the car, such as the breaking of the load-bearing cables, is prevented by a safety gear device. In most cases, the braking force of the safety gear device is set to the average payload of the elevator installation. The car decelerates optimally only when it is carrying an average payload. If the payload is higher than the average payload, the safety gear device slows down the car more slowly, resulting in longer braking distances. If the payload is lower than the average payload, the safety gear device slows down the car faster and the load on the car components will increase. In this case, an increased risk of damage to the elevator equipment and injury to passengers may result. [0003] WO 2016 071141 A1 disclos...
