Patent ID: 8166886

Claim:
A wear monitoring system for monitoring wear and abrasion of at least one system component of a cable operated transportation system, comprising: at least one of a support cable, a traction cable, and a hoisting cable, at least one drive unit, a parameter measuring device for measuring at least one of: (a) an actual value of; and (b) a time-dependent actual value function of, at least one of an electrical parameter and a mechanical parameter of at least one of the at least one system component and the at least one drive unit, the at least one system component being subjected to wear and abrasion and being mounted in a rotating and/or a circulating manner, and an evaluating device for determining a parameter deviation of: (i) the actual value from a desired value in dependence on at least one of time or a time interval of, and (ii) the actual value function from a time-dependent desired value function of, the at least one electrical and mechanical parameter, the parameter deviation corresponding to at least one of a state of the abrasion and wear of the at least one system component, wherein the parameter measuring device comprises at least one of a torque measuring device, a rotational speed measuring device, an angular speed measuring device, a current measuring device, and a voltage measuring device for measuring the at least one mechanical and electrical parameter as at least one of torque, a rotational speed, an angular speed, a drive current of the at least one drive unit, and a drive voltage of the at least one drive unit.
