SUSPENSION ROPE WEAR DETECTOR

摘要

A wear detector (2) for a suspension rope (4) having a plurality of load bearing strands (6) covered by a sheath (8) includes a sensor at a surface of the sheath (8). The sensor senses a characteristic of the rope (4) representing a predetermined amount of wear of the sheath (8). The sensed characteristic can be electrical contact with the strands (6), distance from the surface of the sheath (8) to the strands (6), or change of color of the sheath surface.
