Abstract
A method and a monitoring device determine a wear state of components such as a cable-like suspension means, a traction sheave of a drive machine and deflection rollers of a suspension means arrangement of an elevator system. The method comprises at least the following steps: monitoring an actual time curve of a first parameter which correlates with the wear state of at least one first monitored component of the components; comparing the actual time curve of the monitored first parameter with a predetermined expected time curve of the first parameter; and determining the wear state of the monitored component based on a result of the comparison.
