Method and device for detecting non-uniform and uniform deteriorations in a suspension member arrangement for an elevator based on AC voltage measurements

A method and a device for detecting non-uniform and uniform deterioration states in an elevator's suspension member arrangement (9) comprising at least one suspension member (11) having a first and a second group (24a, 24b) of electrically conductive cords (23) is proposed. First ends (25a,b) o...

Zusammenfassung:A method and a device for detecting non-uniform and uniform deterioration states in an elevator's suspension member arrangement (9) comprising at least one suspension member (11) having a first and a second group (24a, 24b) of electrically conductive cords (23) is proposed. First ends (25a,b) of the groups of cords (23) are electrically connected to an alternating voltage generator arrangement (G, G
