A wear monitoring system is provided for monitoring the wear and/or abrasion of at least one system component of a cable operated transportation system, where the system component is subjected to wear and/or abrasion and is mounted in rotating and/or circulating manner. A parameter measuring device is provided for measuring an actual value and/or a time-dependent actual value function of at least one electrical and/or mechanical parameter of the at least one system component and/or the drive unit. An evaluating device is provided for determining a parameter deviation of the actual value from a desired value in dependence on time or a time interval and/or of the actual value function from a time-dependent desired value function of the at least one parameter. The parameter deviation corresponds to the state of abrasion and/or the state of wear of the at least one system component.
