ABSTRACT:
A synthetic fiber rope can be used to the limit of failure by setting a sensitivity of detection of the state of wear of the rope. Strands of the rope have indicator fibers or indicator yarn that have a high probability of losing electrical conductivity and thereby indicate cable wear. The matrix of the strand with indicator fibers or with at least one indicator yarn has a lower resistance to abrasion than the matrix of the other strands without indicator fibers or indicator yarns.
