Abstract
A wire rope has a lubricated core, an inner jacket in contact with the core, and outer strands wrapped around the inner jacket. An outer jacket surrounds the outer strands and contacts the inner jacket to form an integrated jacket. A method of forming an integrated jacket for a wire rope in which an inner jacket is cold applied and an outer jacket is applied by application of molten material to the inner jacket.
Claims45
A wire rope, comprising:
- a lubricated core;
- an inner jacket contacting the core, the inner jacket including an outward facing surface having open pores;
- outer strands wrapped around the inner jacket;
- and
- an outer jacket at least partly permeated into the open pores of the inner jacket to form an integrated jacket formed of the inner jacket and the outer jacket,
- wherein the inner jacket includes an impermeable layer and the impermeable layer forms a floor formed adjacent to the core.
