Abstract (en)
[origin: WO2017162749A1] The invention relates to an elevator installation (1), wherein damage to a supporting means (7), in particular damage to a sheath of the supporting means, advantageously can be detected. At the elevator installation, a housing (17) at least partially extending around the supporting means (7) is provided, for example at a deflecting roller arrangement (25). A surface (47) of the housing (17) facing the supporting means (7) is electrically conductive and is electrically grounded. If the supporting means (7) or a wire coming out of a damaged supporting means comes in contact with the housing (17), an electrical ground fault results. Said ground fault can be detected by means of a security monitoring unit (19) by monitoring a current flowing through wires of the supporting means, and the damage to the supporting means (7) can thus be inferred
