Abstract
An externally powered car brake for a lift system and, for the activation thereof, a circuit arrangement with integrated stepped control of the deceleration of the car during emergency braking are proposed.According to the invention, a braking system having the full braking force or a braking force adapted to the operating parameters and a subsequent control of the deceleration on the basis of an acceleration measurement with stepped reduction of the braking force are proposed.The control is designed such that the deceleration of the car is always within predefined threshold values, which applies independently of the direction of travel of the lift car, independently of the drive system of the lift used, and independently of the car loading and of the friction coefficient between the brake lining and the guide rail.
