Definitions

  • the present invention relates to a rope or a rope element, which is used for the production of a rope.
  • a reinforcement in the context of the present invention is therefore to be distinguished from a complete sheathing of a rope or a rope element, in which the entire surface is covered by another material.
  • the object of the present invention is to overcome the mentioned disadvantages of the prior art and in particular to provide a cable which, with at least a consistently high service life and load capacity, additionally has improved static friction properties.
  • rope element means any subunit of a rope, e.g. a strand or a twine used as a fibrous material, which forms with other subunits a rope or larger subunits of a rope.
  • a “deviating" fiber material is to be understood as meaning a fiber material which differs from the fiber material of the rope or rope element, e.g. in terms of its chemical nature (e.g., different base polymer) or textile properties such as titer, texturing, twisting (e.g., twisting), etc.

  • Also suitable as material b) are all non-impregnated monofilaments which have improved stiction properties compared with monofilaments conventionally used as reinforcing material.
  • Particularly suitable as material b) are monofilaments having an elongation at break of at least 27%.

  • a portion of the strands of threads of the materials a) and b) may be knit and another part of the strands of threads of the material c) braided or a part of the strands with threads of the materials a), b) and c) knits and another part of the strands with threads of the materials a), b) and c) be braided.
  • the grip of the rope or rope element can be influenced not only by the type of reinforcement, but also by the choice of the fiber material of the rope element.
  • a further preferred embodiment of the present invention is therefore characterized in that optionally impregnated multifilament yarns of polyamide and / or polyester multifilaments are provided as the fiber material of the cable element.
