Choker rope and choker rope system

The present invention relates to a choker rope, which is releasably fixable with a first end to a pull or return rope and releasably fixable with a second end to a tree to be backed, and a choker rope comprehensive Chokerseilsystem.

In the forestry industry, steel ropes are usually used as back ropes, traction ropes and the like, especially as choker ropes for wrapping around and removing tree trunks. In particular, the ropes in this field of application are subject to high demands in terms of their tensile strength and their abrasion resistance, since the ropes are used e.g. on the forest floor and over tree trunks.

However, this leads to the fact that the ropes are usually heavy and unwieldy, since made of steel. Handling is often cumbersome due to weight and low flexibility. In particular, the formation of a loop for looping a tree is difficult in steel cables and must be supported by various complex measures such as additional components and assembly steps.

The present invention thus has for its object to provide a choker rope made of a textile fiber material, which is easy to transport and handle and can be placed in particular in a simple and reliable manner without additional pieces of rope in loops or loops and thereby the above avoids mentioned disadvantages.

This object is achieved by a choker rope according to the type mentioned above in that the choker rope consists of a textile fiber material. Surprisingly, it has been shown that a textile rope to the requirements set in the forestry operation quite well and in conjunction with suitable connection measures a simple, cost-effective and versatile and thereby very reliable and resilient alternative to steel cable in the forestry sector.

For use in the forestry sector is advantageous if the Chokerseil has a sheath-core construction, in which the core is high strength. Preferably, the core is designed with a strength of at least 150 cN / tex, in particular of at least 180 cN / tex, since the loads are considerable.

The fibrous material of the core is preferably selected from the group consisting of high strength fibers, especially high strength high modulus polyethylene fibers, aramid fibers, liquid crystalline (LC) polyester fibers, polybenzoxazole as well as mixtures thereof which experience has shown to have high strength.

The fiber material of the jacket is advantageously selected from the group consisting of highly abrasion-resistant fibers, especially high-strength high-modulus polyethylene fibers, liquid-crystalline (LC) polyester fibers, other abrasion-resistant polyester fibers, polyamide fibers and mixtures thereof, since these materials have, according to experience, a high abrasion resistance.

The choker cable according to the invention advantageously has at least one first device for forming a self-tightening loop under the action of a tensile force, whereby the task of Chokerseils for wood backing is only possible.

Said first device may be a slide displaceably arranged on the choker rope and a hanger connectable to the slider, in which the choker rope can be inserted, or a slider slidably mounted on the choker rope and a nipple connectable to the slider and formed on the choker rope, or a rope loop formed on the choker rope, the individual components advantageously being combinable with each other.

Furthermore, it is advantageous that the choker rope has at least a second device for connecting the choker rope with a pull or return rope, whereby the removal of the wood is made possible.

The said second device may be a slidably mounted on the pull or Rückeseil slider and connectable to the slider hanger into which the Chokerseil is inserted, or on the pull or Rückeseil slidably mounted slider and connectable to the slider nipple, the formed on the choker rope, or a rope loop formed on the choker rope, • ································································································· It is also possible to combine the individual components in an advantageous manner.

A particular advantage in this case is to be seen in that the first and second devices can be combined with one another as desired. This means that the choker rope according to the invention, for example, both a first device in the form of e.g. a rope loop as well as a second device in the form of e.g. a nipple and a slider, etc.

According to an advantageous embodiment variant, it can be provided that the choker rope is fixed in itself, forming at least one cable loop, wherein the at least one cable loop is formed by a textile seaming of cable sections lying parallel to one another. This embodiment is particularly easy to produce and still has sufficient durability compared to the demands made on a choker rope requirements.

The choker cable can also have a cable loop with a textile seam at both ends in an alternative embodiment, whereby a large range of possible combinations with other components is given.

In a particularly preferred embodiment, at least one of the rope loops may comprise a band loop with a toggle, the band loop being incorporated into the textile seam, in particular sewn in, or fixed to the at least one loop by means of a separate seam. By the gag a particularly simple looping is possible.

The gag may be rod-shaped, in particular circular-shaped, T-shaped, dumbbell-shaped or U-shaped and comprise a recess for fixing to the belt loop. The shape of the toggle can thereby be adapted to different conditions during forestry operation, for example for particularly simple loosening of the loops, for particularly reliable connection to the pull or return rope, etc.

The toggle can be releasably inserted into the cable loop while repelling the cable loop and forming a loop, whereby a connection is given, which can be opened and closed even under difficult conditions.

The choker rope can then be guided through the loop to form a loop, whereby the tree to be moved back safely on the pull or return rope is suspended. ι ···················································

If, as part of the first and / or second device, a hanger and a displaceably arranged slider are used, the hanger is advantageously positively and releasably connectable to the slider, which is slidably mounted on the choker rope and / or on the pull or return rope. The positive connection ensures a very reliable connection.

Alternatively, the choker rope may be provided at one or both ends with a retractor looped into the choker rope, which in turn allows many advantageous combination possibilities to be realized with other components.

An advantageous embodiment provides that the catcher has a mouth into which the choker rope can be inserted, in particular can be looped around a pin arranged in the mouth. The hanging is easy to perform and can be carried out under difficult conditions with wet or dirty ropes.

If the choker rope is already provided with a rope loop, it can be hooked into the mouth of the tag without further measures such as knotting, etc.

If the choker rope has a nipple as part of the first and / or second device, then the nipple can be positively and detachably connected to the slider in a very advantageous manner, so that a simple hooking into the slider is possible.

Advantageously, the choker rope may have a nipple at one end or at both ends, whereby a large number of possible combinations with other components is likewise possible.

The nipple may be connected to the hanger or formed integrally therewith. As a result, different shaped sliders can be used.

Furthermore, it is advantageous that the choker rope is reinforced in the region of the at least one cable loop and / or in the region of the at least one textile seaming, in particular by a fixed or displaceable rubber or plastic casing, a wrapping with a suitable material or an interweaving of reinforcing material in the textile fiber material of the rope, as by this measure the choker rope or the Vemähungen can be protected against contamination and damage.

A choker rope system advantageously comprises a choker rope and a rope glider slidably mounted on a pull or return rope and releasably connectable to the choker rope.

The rope glider can be the slider corresponding to the intermediate piece, which advantageously makes it possible to use the sliders which can also be used with the conventional steel cable.

Furthermore, the rope glider can be designed in the form of a carabiner or a metal ring, which offers a particularly simple and cost-effective possibility of hanging.

If one of the rope loops is designed to be suitable, it is also possible that the rope loop of the choker rope is hung directly on the pull or return rope, which eliminates the need for other components.

Preferred embodiments of the invention are illustrated by way of example in the figures and described in more detail with reference to the drawings. Show it:

1A-B is a schematic representation of a Chokerseils according to the prior

Technology as well as an enlargement of its essential components,

2A-D components of an embodiment of an inventively designed Chokerseils, and

Fig. 3 A-B, a particularly preferred embodiment of an inventively designed Chokerseils and various embodiments thereof.

Before discussing preferred embodiments of a choker cable designed according to the invention, a known choker cable will first be briefly explained in terms of its design and use for better understanding of the inventive measures with reference to FIGS. 1A and 1B.

In Fig. 1A, a choker rope 1 is shown schematically. The choker rope 1, also known as choker rope, is preferably used in forestry for wood backing. The choker rope 1 is placed around a tree trunk to be backed up and pulls itself by the weight of the same automatically, so that the tree trunk is raised and, for example, ··· ·· ···· ·· ·· ······ · · · · · · · · · ······ ······ or Rückeseil on which the Chokerseil 1 is hooked, can be removed.

The choker rope 1 is made of a steel cable 2, which at one end a terminal nipple 3, which consists for example of metal and is welded to the steel cable 2, and at a 2weiten end a rope loop 4, which is connected to a cable slider 5, having. The cable slider 5 is executed in the illustrated embodiment as a metal ring which is slidably mounted on a train or return rope, not shown. The cable loop 4 can be secured, for example, by a pressed or welded sleeve 6.

The nipple 3 corresponds to a slidably mounted on the steel cable 2 slider 7, wherein the nipple 3 in a recess 8 of the slider 7 can be suspended. Due to the shape of the nipple 3 and the recess 8, in particular by an undercut shape of the recess 8, it is ensured that the nipple 3 does not come off the recess 8 of the slider 7 during the wooden back.

In Fig. 1B, the nipple 3 and the corresponding slider 7 are shown enlarged. The slider 7 is, as mentioned above, slidably disposed on the steel cable 2, which passes through an opening 24 in the slider. Due to strong frictional forces between the two metallic Gleitpartnem, especially in pollution, which often occurs in the forest, it always comes back to fatigue fractures of the slider 7 when the material thickness decreases too much due to heavy wear. A chamfering of individual wires of the steel cable 2 also has a negative effect, since a splitting of the cable 2 can, for example, lead to the slider 7 no longer being able to slide on the steel cable 2, but sticking in the opening 24.

In contrast, the inventively designed Chokerseil 1 is made of a textile fiber material, which can reduce the one hand, the disadvantages mentioned above or completely avoided and on the other hand, the handling of the invention Chokerseils 1 due to its greater flexibility and its lower weight is considerably simplified.

The choker rope 1 is preferably formed in the form of a fiber rope 14 with Kem-sheath structure, wherein the core has at least a strength of 150 cN / tex, preferably of more than 180 cN / tex. Preferred materials of the fiber material of the core are selected from the group consisting of high-strength fibers, in particular high-strength high-modulus modules. • ·· ♦ · ······· 7

Polyethylene fibers, Aramidfasem, liquid crystal (LC) polyester fibers, Polybenzoxazolfasem and mixtures thereof selected. The sheath of the choker rope 1 is selected 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. This can ensure that the choker rope 1 is high strength and thus has a high life expectancy and a low tendency to wear.

In Fig. 2, individual components of an inventively designed Chokerseils 1 are shown schematically. The individual components can be combined into a device which can serve both for the formation of a loop for wrapping the tree and for hanging the choker rope 1 on the pull or return rope. The individual components can be selected as required by the operating conditions. The device can combine identical or different components for both connections.

In Fig. 2A, first a cable loop 4 is shown. The fiber rope 14 of the choker rope 1 is fixed in itself, wherein the rope loop 4 is formed by a textile Vemähung 9 parallel cable sections. The cable loop 4 may be terminal, as shown in Fig. 2A, but also be formed at any point on the rope length of the choker rope 1. For use in the forestry sector, a terminal cable loop 4 is assumed here. The choker rope 1 can have a cable loop 4 at one end or on both sides.

The at least one cable loop 4 can be suspended in a hanger 10, which is shown in FIG. 2B. The hanger 10 is known in principle, but only in combination with a steel cable 2, as mentioned above. The at least one cable loop 4 is inserted, for example, in a mouth 11 of the trailer 10 and secured by a bolt 12. The bolt 12 can be detachably inserted in particular through holes 13 in the mouth 11. Alternatively, it is also possible to form the bolt 12 in one piece with the hanger 10. This then requires, during the production of the choker rope 1, first to lay the fiber rope 14 about the pin 12 and then to close the rope loop 4 through the seam 9. The first variant has the advantage that the cable loop 4 is releasably connected to the retainer 10 and thereby easier solvable or replaceable, the latter variant is indeed more expensive to produce and not solvable, but forms a composite through which the intermediate piece 10 is captive. ···· ·· • · " ··· ·· ··· ···· ·· 8th

The hanger 10 also has an extension 19 with a nipple 3 formed thereon. The extension 19 is preferably formed with respect to the mouth 11 of the Einhängers 10. The hanger 10 may, as shown in the exemplary embodiment, be formed in one piece or in several parts, for example, to form a joint. The nipple 3 is used for connection with a slider 7 to form a loop around the tree or for hanging the choker rope 1 on the pull or return rope.

The slider 7 is shown schematically in Fig. 2D and also known per se. The slider 7 can be embodied in particular in a similar form as the slide 7 already described with reference to FIGS. 1A and 1B with respect to the prior art. This is all the more advantageous as existing sliders 7 can continue to be used, even if they no longer run on a steel cable 2, but on a textile fiber rope 14 according to the invention. The slider 7 is displaceably arranged on the fiber rope 14 or on the pull or return rope, wherein the tension or return rope is guided through the opening 24 in the slider 7.

The connection of the Einhängers 10 with the slider 7 is made by hooking the nipple 3 of the tag 10 in a recess 8 of the slider 7. Due to the shape of the nipple 3 and the undercut shape of the recess 8 of the slider 7, it is possible the Einhänger 10th reliably connect to the slider 7. Due to the fact that the force always acts in such a way that the nipple 3 is more strongly drawn into the recess 8, both in the formation of the loop looping around the tree and when hanging the choker rope 1 on the pull or return rope, an automatic release of the engagement of the Both components remain virtually impossible under load, even when the tree is hanging or when the tree is being dragged along the ground, creating a very secure and reliable connection.

In Fig. 2C, another component of the compound is shown, which is formed in the form of a terminal nipple 3 on the Chokerseil 1. The nipple 3 can be connected to the fiber rope 14 by crimping, plastic welding or other suitable method for connecting a fiber rope 14 with a metallic sleeve-like nipple 3, for example by a splint, a screw or a clip, the nipple 3 and the fiber rope 14th penetrates.

The terminal nipple 3 on the choker rope 1 replaces the combination of the cable loop 4 with the hanger 10, so that only the terminal nipple 3 must be suspended in the slider 7 to form a loop or for hanging the choker rope 1 on the pull or return rope. The connection can be seen analogously to the connection formed by the nipple 3 of the hanger 10 in the slider 7.

The choker rope 1 can thus be present in various designs, which include any combinations of the individual components. The following overview indicates some possible combinations with a terminal arrangement of the components cable loop 4 and nipple 3: Choker cable 1 with two terminal nipples 3, which can be suspended in one slider 7 each, one on the choker cable 1 and the second on the pull cable or Rückeseil is arranged displaceably. This variant is very simple and above all very versatile. - Choker rope 1 with a terminal nipple 3 and a terminal cable loop 4, which is connected to a hanger 10, wherein the nipple 3 with a slider 7 and the nipple 3 of the hanger with a second slider 7 is connectable. Which of the nipple 3 is mounted in the arranged on the pull or return line slider 7 and which is mounted in the arranged on the choker rope 1 slider 7, is freely selectable. - Choker rope 1 with two terminal rope loops 4, which are each connected to a hanger 10, which are suspended in a respective slider 7, one of which is arranged on the choker rope 1 and the second on the pull or reverse rope slidably.

Choker rope 1 with two terminal rope loops 4, wherein one of the two rope loops is hooked directly (i.e., without intermediate piece) into a pull or return rope and the other rope loop, in particular in the preferred embodiment of FIG. 3 described below, serves to wrap around the tree.

Embodiment variants which have cable loops 4, which are not arranged terminal, are also possible.

In FIG. 3A, in different perspectives, a particularly preferred alternative of a cable loop 4 for a choker cable 1 configured according to the invention is shown.

At least one of the rope loops 4 in this case has a belt loop 15 with a knob 16, wherein the belt loop 15 incorporated into the textile Vemähung 9, in particular sewn, or even by a separate Vemähung 18, which is spaced from the Vemähung 9 of the parallel cable sections fixed be. The cable loop 4 is referred to below with reference to FIGS. 3A and 3B by the reference numeral 20 in order to distinguish them from the cable loop 4 according to FIG. 2A.

The knob 16 may take any suitable forms, it may, for example, as shown in the embodiments schematically illustrated in FIG. 3B, rod-shaped, in particular round rod-shaped, T-shaped, dumbbell-shaped with lateral discs 23 or U-shaped with legs 22 which are perpendicular extend to the knob 16, be formed. However, the knob 16 is not limited to the illustrated embodiments. A recess 21 is provided, by which a fixation of the knob 16 in the band loop 15 is possible. In particular, the recess 21 may be slot-shaped, so that the belt loop 15 itself may be looped through the recess 21 and the knob 16 is thereby captive.

The knob 16 is releasably inserted into the associated cable loop 20 while repelling the cable loop 20 and forming a loop 17. Through the loop 17, the choker rope 1 can again be guided to a loop which wraps around the tree to be moved.

The cable loop 20 can be used as an alternative to the cable loop 4 shown in FIG. 2A or combined with it, so that one of the terminal cable loops 4,20 is a cable loop 4 according to FIG. 2A, while the second terminal cable loop 4,20 a According to FIG. 3A or in one of the forms according to FIG. 3B trained rope loop 20 may be. The cable loop 20 provided with the toggle 16 can in particular also be combined with a retainer 10 according to FIG. 2B, the toggle 16 then not being used.

A provided with one or two of the rope loops 20 shown in Fig. 3 A 20 Chokerseil is particularly easy to handle and can get along in the best case without further parts. In particular, it is possible to use a choker rope 1 only with terminal rope loops 4 and / or 20 by looping the choker rope 1 around the tree and looping the choker rope 1 through one of the terminal rope loops 4 or 20, and then directly on the train - or Rückeseil is hooked to form a loop 17 by means of trained on one of the cable loops 20 toggle 16.

If the choker rope 1 is provided with rope loops 4, 20, it is expedient to protect them from abrasion and contamination, both in themselves and their dimensions 9, 18. For this purpose ··· ······ The choker cable 1 can be reinforced in the region of the at least one cable loop 4, 20, in particular by a fixed or displaceable rubber or plastic casing (not shown in further detail). *** " In order to keep the effort small, the choker rope 1 can at least in the region of the at least one textile Vemähung 9 and / or in the area of Vemähung 18 of the belt loop 15 be covered by a protective cover, not shown, in particular by a fixed or sliding plastic casing or wrapping with a suitable material. This makes it possible to protect the at least one cable loop 4, 20 and / or at least the fastening 9 and / or 18 fixing the cable loops 4, 20 from damage caused by abrasion, contamination or other influences.

The connection of the choker rope 1 with the pull or return rope can continue to take place via a carabiner or a metal ring as a cable slider 5. If the cable slide is designed in the form of a simple metal ring, a circular ring is the preferred choice, since oval shapes can cause wear due to friction always at the same point, whereas a circular metal ring can be replaced by alternating loading and unloading rotated and thus worn evenly. An embodiment of the ring in the form of an eight is possible and advantageous. The cable slider 5 is in turn combined with any possible combination of cable loops 4,20, Einhängem 10 and nipples 3 with sliders 7.
