An elevator installation has a support device engaging a driven drive pulley for driving an elevator car. The support device loops around the drive pulley at least partly and has a safety section which is so arranged that the safety section interacts with the drive pulley when the elevator car or a counterweight after overrunning an upper position approaches an upper shaft end. The safety section is formed in such a manner that a slipping through results due to the interaction between the drive pulley and the support device.
