Abstract
A rope including a heat sensitive component which is subject to a visible change in appearance, such as a color change, when exposed to a selected elevated temperature resulting from a strain-related heat release from the rope. The heat sensitive coating may be contained in a coating over a fiber of the rope or a rope strand, or may be incorporated in sheath located over the load-bearing core of the rope.
