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