Abstract:

A method may be used to monitor the health of a belt in an elevator system. The belt may include first and second terminal ends, a plurality of conductive load carrier strands that extend between the first and second terminal ends, and a polymer material surrounding the strands. A measuring connection point may be located between a pair of adjacent carrier strands at each terminal end of the belt. The method may involve electrically connecting a measuring apparatus between the pair of strands at the measuring connection point at each terminal end and measuring an electrical characteristic at each connection point between at least one pair of strands. The electrical characteristic measured over the complete width of the belt gives a complete overview of the health of the belt, as a change in the measured electrical characteristic over time will be indicative of damage within one or more strands.
