Abstract

The wire rope of this invention has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.

Claims

1. A wire rope having at most 18 outer strands and an independent wire rope core, with strands of the core being laid in opposite direction to the outer strands of the wire rope making such wire rope essentially non-rotating during application of a load, characterized in that a nylon jacket is provided between the outer strands and the core of said wire rope.

2. A wire rope according to

claim 1

, in which the nylon jacket has a thickness such as to substantially prevent perforations to occur in said jacket before occurrence of degradation of the outer stands of the wire rope.

3. A wire rope according to

claim 1

, in which the core is lubricated.

4. A wire rope according to

claim 1

, in which the outer strands of the rope crosscut the strands of the core at approximately 90°

angle.

5. A wire rope according to

claim 1

, which is a rope with eight outer strands.
