Definitions

  • the present invention relates to a rope made of a textile fiber material.
  • Desirable is also a simple determinability of the Ablegereife, i. that point in time at which the rope must be preventively replaced due to excessive damage due to ongoing operation.
  • Sheathless ropes are known from a high strength textile fiber material (e.g., Dyneema® fiber, a high strength and high modulus polyethylene (HMPE) fiber material).
  • HMPE high modulus polyethylene
  • the present invention has for its object to provide a rope made of a textile fiber material, which is particularly suitable for use for ropes of all kinds, in particular winches, and does not have the disadvantages mentioned above.
  • a rope of textile fiber material which is present in a conventional manner in a core / shell construction, which rope is characterized in that the specific strength of the rope F s (in [daN / g core / m Rope]) depending on the diameter of the rope DM (in [mm]) of the following formula: F s ⁇ 212 - DM and that the core of the rope is stretched to an extent greater than 5% of the maximum tensile force of the core.
  • Ropes made of a textile fiber material which are present in a core / shell construction, are known per se, see for example the document US 2005/011344 A1 .
  • Such a rope consists of one or more, for example braided or beaten core (s) of textile fiber material, which (r) of a textile fiber material wrapped as a jacket, for example, is braided or are.
  • core will be understood hereinafter to mean both a single core and a plurality of cores present in a cable.
  • the invention now provides for the first time a textile rope with a core / sheath structure which has similarly good tensile strengths and abrasion resistance as a steel rope of comparable thickness.
  • the diameter DM of the rope according to the invention is preferably 4 to 60 mm, preferably 4 to 40 mm, particularly preferably 4 to 26 mm.
  • the core of the rope according to the invention is stretched to an extent of more than 5%, preferably 5.5% to 20%, more preferably 6% to 15% of the maximum tensile force of the core.
  • the core of conventional ropes having a core / sheath construction is usually stretched only up to a range of up to 5% of the maximum tensile force.
  • the stretching of the core is carried out at a temperature which is elevated in relation to room temperature, in particular at an ambient temperature up to the melting range or decomposition range of the polymer used as the fiber material of the core.
  • the temperature ranges suitable for the respective fiber material of the core can be determined by one skilled in the art within the scope of his specialist knowledge.
  • an ambient temperature of from 50 ° C to 140 ° C, preferably from 90 ° C to 120 ° C, is preferred.
  • the diameter of a preferably highly stretched core according to the invention is smaller than less oriented cores. This makes it possible, despite applying a jacket on the core to obtain a rope which is not substantially thicker than a steel cable of equal tensile strength. At the same time, the sheath ensures protection of the core and improved abrasion resistance over a rope made entirely of a core of high strength fibers.
  • the fiber material of the core is preferably selected from the group consisting of high-strength fibers, in particular high-strength high-modulus polyethylene fibers, aramid fibers, liquid-crystalline (LC) polyester fibers, polybenzoxazole fibers and mixtures thereof.
  • high-strength fibers in particular high-strength high-modulus polyethylene fibers, aramid fibers, liquid-crystalline (LC) polyester fibers, polybenzoxazole fibers and mixtures thereof.
  • High strength high modulus polyethylene fibers are commercially available under the trade name Dyneema®.
  • LC polyester fibers are commercially available under the trade name Vectran®.
  • the fiber material of the sheath from the group consisting of highly abrasion-resistant fibers, in particular high-strength high modulus polyethylene fibers, Liquid crystalline (LC) polyester fibers, other abrasion-resistant polyester fibers, polyamide fibers and mixtures thereof selected.
  • highly abrasion-resistant fibers in particular high-strength high modulus polyethylene fibers, Liquid crystalline (LC) polyester fibers, other abrasion-resistant polyester fibers, polyamide fibers and mixtures thereof selected.
  • the rope according to the invention preferably has means for increasing the adhesion between core and sheath of the rope.
  • At least a part of the surface of the core may be enveloped with a material selected from the group consisting of staple fiber yarns and textured multifilament yarns.
  • This sheath can be present, for example, in a manner known per se in the form of a reinforcement, a braiding or in the form of fibers with increased adhesion, which are braided to the core and at least partially lying on its surface.
  • Polyamide, polyester, polyacrylate, polypropylene, polyethylene and mixtures thereof are particularly suitable as material for the covering.
  • sutures can be provided between these components.
  • At least part of the surface of the core may be coated with an adhesion-enhancing substance.
  • the jacket itself or the cable elements forming the sheath such. Yarns or threads may be coated with an adhesion-enhancing substance.
  • the jacket has markings by means of which an elongation of the rope and / or a twist of the rope can be detected.
  • the markings may for example be fixedly spaced. If the mantle contains fixedly spaced markings (eg, individual differently colored braids at a fixed distance of, for example, 10 cm), it can be checked before use of the rope whether this distance has changed, in particular lengthened, due to an extension of the rope and therefore indicates a Ablegereife.
  • fixedly spaced markings eg, individual differently colored braids at a fixed distance of, for example, 10 cm
  • a pattern of marks e.g., stripe patterns or other markings along the length of the rope
  • a twist of the rope is unfavorable and significantly reduces the tensile strength of the rope. Therefore, turning back to the original, i. torsion-free shape of the rope necessary.
  • the rope according to the invention is particularly suitable for use in cable devices, in particular in the field of agriculture and forestry and the construction and transport industry.
  • an equivalent alternative to steel ropes for the first time an equivalent alternative to steel ropes, but at a much lower weight (a rope according to the invention typically has a weight of only about 20% of the weight of a comparable steel rope) can be provided.
  • the rope according to the invention as a supporting rope, guy rope, pull rope, hoisting rope, return rope or rope in ropes, mast ropes and winches according to the example in the ⁇ standards L 5219 and L 5276 in terms of mobile ropes for wood handling or rinsewinden for land and Forestry used definitions.
  • a preferred method of making the rope of the present invention comprises making a rope core of textile fiber material and wrapping the rope core with a cladding of textile fiber material and characterized in that the rope core, prior to wrapping with the clad, is greater than 5%, preferably 5.5% to 20%, particularly preferably 6% to 15% of the maximum tensile force of the core is stretched.
  • the stretching of the core can preferably be carried out at a temperature which is elevated in relation to room temperature, in particular an ambient temperature, up to the melting range or decomposition range of the polymer used as the fiber material of the core.
  • the stretching of the core may preferably be carried out at an ambient temperature of 50 ° C to 140 ° C, particularly preferably 90 ° C to 120 ° C.
