Abstract (en)

[origin: US2008236954A1] A method of preventing a collision of two elevator cars of an elevator installation, which cars move substantially independently of one another in a common shaft, and an elevator installation includes a collision protection system that produces a retardation of each moved elevator car by a stopping brake as soon as the effective distance between the elevator cars falls below a critical minimum distance. After retardation of the cars by the stopping brakes, an emergency stop system comes into function. A control system of this emergency stop system ascertains the instantaneous movement state of the elevator cars. With the help of the car brakes, which are associated with the elevator cars, an additional retardation of each moved elevator car is triggered when the movement state thereof fulfils definable emergency stop criteria.
