Abstract

In a rope comprising a bundle of wires (21, 31, 32) each of which is adapted to bear a tensile load to be borne by the rope, predetermined one (32) of the wires is configured to be at least partially breakable by applying tension and flexure to the rope, before an at least partial breakage of a rest of the wires (21, 31) other than the predetermined one (32) of the wires by applying the tension and flexure to the rope.
