- the invention relates to a rope made of textile fiber material and its use.
- Ropes made of textile fiber material for example synthetic fiber ropes, are used for numerous applications. Particularly in the field of conveyor technology, high-strength fiber ropes are already superior to the previously exclusively used or available steel ropes due to several advantages.
- a high-strength fiber rope depending on the fiber material compared to a steel cable has a 4-6fach lighter weight, which has a favorable effect especially at high elevator heights.
- higher permissible bending cycle numbers can be achieved by a multiple of high-strength fiber cables, resulting in a longer service life, ie lifetime, of the cable compared to steel cables.
- the known elevator fiber ropes are designed in a variety of constructions, where they usually a sheathing of the strands and a
- the sheathing is designed in such a way that it permanently withstands the loads during running over pulleys and in particular traction sheaves.
- Such high-strength fiber ropes for use in traction sheave elevator drives are known, for example, from EP 0 672 781 B and EP 0 934 440 B.
- Lifting applications in lifting technology do not use traction sheave drives but drum drives with multi-layered rope drums.

- the cable according to the invention has at least two, preferably at least three concentric load-bearing strand layers.
- the respective outermost layer of strands preferably has the direction opposite to the direction of impact of the inner strand layers

- a strand even if it acts load-bearing, partially contain materials that do not load bearing.
- the degree of filling of the rope of textile fiber material is> 75%, preferably> 85%. It has been shown that a high degree of filling of the rope to fiber material, that is a very dense arrangement of the fiber material, both in terms of solving the problems described above in the application as well as in terms of the life of the rope itself is important.
- the degree of filling of the rope on textile fiber material is determined by the measuring method described in detail below. It comprises all load bearing as well as non load bearing textile elements of the rope, e.g. also a core of textile fiber material or a sheath of textile fiber material.
- the rope according to the invention also has a low content of non-textile binding and impregnating agents. This proportion is 10% by weight or less, preferably 5% by weight or less, in each case based on the total mass of the rope.
- the outermost layer of the rope according to the invention has a coefficient of friction ⁇ with respect to steel of ⁇ ⁇ 0.15.

- This jacket can be made of textile fiber material, but also other materials and be wound, laid, braided or extruded.
- the low coefficient of friction of the jacket ensures very good sliding properties in multi-layer winding.
- the strand layers are coordinated so that the rope is substantially free of rotation under load.
- the Litzenlagen the rope according to the invention in diameters, cross-sectional proportions and impact angles are coordinated so that the Litzencardmomente cancel each other under load and the Spirallitzenseil is torque-free in this way.

- Ratio of the lay length of at least one of the layers of strands to the lay length of the adjacent in the direction of the cable center strand layer is less than 1.5, preferably 0.7 to 1.0, particularly preferably 0.8 to 0.9. This applies in particular to the ratio of the lay length of the outermost layer of strands to the adjacent inner layer of strands. Particularly preferred is a structure of the rope with three layers of strands, in which the ratio of the lay length of the outermost layer of strands to the center strand layer is 1.0 or less.

- the density p of the textile rope material is set at 1.4 g / cm 3 for the purposes of the present invention.
- the rope is pulled over a standing metal disc with a flat surface (no scoring). Due to the friction of the rope to be tested, the disc is taken more or less strongly.
- the disc is fixed, a load cell measures the force passing through the entrainment is caused by the rope to be tested.
- the measuring device is shown schematically in Fig. 4.
- the surface of the disc must be flat (no scoring) and may have a maximum average surface roughness of R A ⁇ 0.2 ⁇ .
- the surface of the glass should be cleaned with alcohol.
- the rope is clamped on the tension side.
- the rope is loaded with constant load M on the load side.
- the rope must rest on the center of the disc.
- the measuring device is tared to 0.
- the constant tensile load S2 occurring during the pulling process must be measured with an accuracy of + 3%.
- FIG. 1 shows a cross-section of a preferred embodiment of the cable 1 according to the invention.
- FIG. 2 shows a perspective view of the cable 1.
- the rope 1 contains a core 2 of preferably textile fiber material.
- a core 2 of preferably textile fiber material.
- three concentric Litzenlagen 3, 4 and 5 are provided, each consisting of several strands and are stranded together in the form of a Spirallitzenseiles.
- the innermost strand layer 3 consists of 5 strands, of which two strands are denoted by the reference numerals 7 and 8 in the figure.
- the middle strand layer 4 consists of 12 strands, of which in the figures two strands with the
- the outermost strand layer 5 consists of 19 strands, of which two strands are denoted by the reference numerals 11 and 12 in the figures.
- the fiber material of the strands consists essentially of high strength plastic fibers, e.g. UHMWPE fibers, aramid fibers, LCP fibers or PBO fibers.
- a jacket 6 is provided in the illustrated embodiment. But it can also represent the outermost strand layer 5, the outermost layer of the rope.
- the jacket 6 has a coefficient of friction ⁇ with respect to steel of ⁇ ⁇ 0.15 and is preferably made of textile fiber material, e.g. UHMWPE manufactured. If no sheath 6 is provided, then the fiber material of the outermost strand layer 5 has a correspondingly low coefficient of friction ⁇ .
- all the strands 7, 8, 9, 10, 11, 12 and also the core 2 are provided with a sheath, which is indicated in FIGS. 2 and 3 for a strand with the reference number 13.
- the strand layers 3, 4 and 5 are movable against each other and also relative to the core 2 and the sheath 6. Likewise, the individual strands 7, 8, 9, 10, 11, 12 are mutually movable.
- the outermost strand layer 5 and the middle strand layer 4 are stranded with one another in the opposite direction of impact.
- the degree of filling of the rope of textile fiber material is 85% (not apparent from the schematic representations of the figures).
- the ratio of the lay lengths of the individual layers of strands to each other is not shown in the figures, but is in particular in the case of the outermost layer of strands (5) to the middle strand layer (4) preferably 1.0 or less.
- FIG. 3 shows the perspective view of a cable 1 with an otherwise analogous construction to the cable 1 shown in FIGS. 1 and 2, only two strand layers 3 and 4.
