Abstract
An elevator installation has a vertical elevator shaft, an elevator car vertically displaceable in a vertical direction in the shaft, a load-bearing device connected to the car and guided to a counterweight via a drive pulley, and a compensation element connected to the car and guided to the counterweight. A blocking device selectively secures the compensation element in the elevator installation such that, with the compensation element secured between the car and the blocking device, a tensioning force can be generated in the compensation element. The blocking device is used in a method for positioning the car in a desired position in the elevator installation.
