Abstract
An elevator installation includes a guide rail and brake equipment for guiding, holding and braking the elevator installation. The brake equipment has a brake lining which co-operates with a brake surface, advantageously with the brake surface of the guide rail, for the purpose of the braking and holding. The brake surface has at least one longitudinal wedge groove or wedge elevation which is oriented in the braking direction and on which the brake lining acts in case of need. An amplification of the braking force is achieved by the longitudinal wedge groove or wedge elevation.
