Abstract
In order to improve visibility and hence to reduce the risk of accidents, a load-carrying rope, for example a wire rope, is equipped with a number of luminous elements. A luminous element may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids and preferably within the theoretical rope circumference. The luminous element may also itself be composed of luminous elements which are twisted together, spiralled, or laid in so as to form braids. For strain relief, the luminous elements may be equipped with a reinforcement in the form of a strand, or with a mesh.
