Abstract:
An elevator installation includes a first elevator car and a second elevator car, each having a respective braking device, and a safety system that monitors the elevator cars. The safety system has for each braking device a braking force regulating device for regulating a braking force of the respective braking device. The safety system activates at least one of the braking devices by the associated braking force regulating device in order to prevent collision of the first elevator car with the second elevator car.
