Abstract
A composite cable or rope is described. The cable or rope has an inner metallic rope or core, consisting of a plurality of metal strands, and a plurality of covering layers formed around the inner metallic core. An innovative anchoring and safety system is also described. The system has one or more anchorages, fixed to the roof, in each of which the rope is stably locked by screwing, so as not to create instability problems for people attached to the rope.
Claims12
A composite cable comprising:
- an inner metallic core consisting of a plurality of metallic strands, and
- a plurality of layers formed around said inner metallic core,
- said plurality of layers comprising:
- a first fabric layer braided with yarns or threads of aramid fibers or filaments comprising aramid, which first layer is formed around and directly covers said inner metallic core, and
- a second fabric layer braided with yarns or threads of polyester fibers, which second layer is formed around and covers said first layer,
- wherein said composite cable is configured such that, at the tensile strength of the inner metallic core, the composite cable does not break completely, but the inner metallic core ruptures, while said fabric layers covering said inner metallic core maintain a residual strength of the composite cable.
