Title: METHOD FOR DETECTING THE STATE OF SUPPORT BELTS
Abstract:
The invention relates to a method for detecting the wear state of support belts made of elastomer material within a support or elevator system. The support means have tension members or reinforcing elements which are embedded in the belt body in the longitudinal direction of the support means and which are preferably designed as twisted or laid cords. A length (L) of the support means as the length (List(Ein)) which is measured after reaching a new run-in state is correlated to the corresponding support means length (List) or (List(n)) which is measured after a specified operating time has expired or a specified number of load cycles is reached. A warning signal is emitted or required for exchanging the support means after a specified ratio of the lengths (List/LEinl) or (List(n)/LEinl) is reached.
