Integrated safety of the elevator system can be used in any of the lifts for the movement of people and goods from one floor to another. The system is fixed on the upper or lower lift beams and comprises at least two braking devices. The braking device comprises wheels mounted on the same shaft fixed to the hubs. One of the disks is fixed rigidly to the shaft, and the other - to be movable along the shaft axis. Between the discs is disposed a rubber wheel which is in contact with the side surface of the brake rail, which can perform the role of guiding the elevator. rotation of the shaft occurs due to forces of friction of the rubber wheel brake tire when moving the elevator car. On the side of the movable disc on the shaft is threaded nut, which abuts the drive through the thrust bearings. The nut is provided with a spring-loaded weights, which, when the elevator car speed exceeds engage with stops formed on the hub. As a result, the nut is screwed on the thread and through the thrust bearing disk drives in the direction of the brake track. The friction force between the tire and the brake disc will gradually increase until it reaches a sufficient braking force to stop the cab. This ensures smooth braking cab, reduced vibration to the cabin at its braking. 1 NC 3 and ZP f ly-2 Fig.
