Abstract
An elevator installation includes a car and at least one support device supporting the car. The support device has a plurality of electrically conductive tensile carriers that are arranged parallel to one another and which are substantially enclosed by a casing. The elevator installation further includes a monitoring device that connects the tensile carriers or groups of the tensile carriers in an alternating configuration as electrical resistances in a measuring bridge so that electrical resistances of different tensile carriers can be compared with one another by sensing a bridge voltage.
