Description

Seilrope
Die vorliegende Erfindung bezieht sich auf ein Seil aus einem textilen Fasermaterial.The present invention relates to a rope made of a textile fiber material.
Im Bereich der Land- und Forstwirtschaft und der Bau- und Transportwirtschaft werden für Seilgeräte, z.B. Seilmastgeräte oder Winden, zumeist Stahlseile als Zugseile, Tragseile u.dgl. eingesetzt.In the field of agriculture and forestry and the construction and transport industries, cable equipment, e.g. Rope masts or winches, mostly steel ropes as traction cables, suspension cables and the like. used.
An Seile in diesem Anwendungsbereich werden insbesondere hohe Anforderungen hinsichtlich ihrer Zugfestigkeit und ihrer Abrasionsbeständigkeit gelegt, da die Seile z.B. am Waldboden und über Baumstämme geführt werden.In particular, high demands are placed on ropes in this field of application 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.
Wünschenswert ist auch eine einfache Bestimmbarkeit der Ablegereife, d.h. jenes Zeitpunktes, an welchem das Seil aufgrund zu großer Beschädigungen durch den laufenden Betrieb präventiv ersetzt werden muss.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.
Aus den obigen Gründen sind derzeit, wie bereits eingangs erwähnt, hauptsächlich Stahlseile für die genannten Zwecke in Verwendung, da sie einerseits eine hohe Zugfestigkeit aufweisen und andererseits auch sehr abriebbeständig sind.For the above reasons are currently, as already mentioned, mainly steel cables for the purposes mentioned in use, since they on the one hand have a high tensile strength and on the other hand are also very resistant to abrasion.
Der Nachteil von Stahlseilen liegt jedoch in ihrem großen Gewicht. Dies ist insbesondere dann nachteilig, wenn die Seile, z.B. beim Aufstellen von Kippmastgeräten, von Hand eingezogen werden müssen.The disadvantage of steel cables, however, is their great weight. This is particularly disadvantageous when the cables, e.g. when setting up tipper masts, must be pulled by hand.
Es wurde daher bereits versucht, Seile aus einem textilen Fasermaterial im Bereich der Land- und Forstwirtschaft einzusetzen. Bekannt sind mantellose Seile aus einem hochfesten textilen Fasermaterial (z.B. der Dyneema®-Faser, einem hochfesten und hochmodularen Polyethylen (HMPE)-Fasermaterial) .It has therefore already been tried to use ropes made of a textile fiber material in the field of agriculture and forestry. 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).
Wenn aber ein Seil aus einem textilen Fasermaterial gleich hohe Zugfestigkeiten wie ein Stahlseil erreichen soll, müssen die Einzelfasern möglichst weitgehend in Seilrichtung ausgerichtet werden, d.h. es müssen Zwirne bzw. Litzen mit geringer Drehung bzw. großer Schlaglänge eingesetzt werden. Dies geht jedoch auf Kosten der Abrasionsbeständigkeit. Zudem ist es schwierig, bei solchen Seilen die Ablegereife zu bestimmen. Die vorliegende Erfindung stellt sich zur Aufgabe, ein Seil aus einem textilen Fasermaterial zur Verfügung zu stellen, welches sich insbesondere zur Anwendung für Seilgeräte aller Art, insbesondere Winden, eignet und die oben erwähnten Nachteile nicht aufweist.However, if a rope made of a textile fiber material should achieve the same high tensile strengths as a steel cable, the individual fibers must be aligned as much as possible in the cable direction, ie, twines or strands with low rotation or large lay length must be used. However, this comes at the expense of abrasion resistance. In addition, it is difficult to determine the Ablegereife with such ropes. 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.
Diese Aufgabe wird durch ein Seil aus textilem Fasermaterial, welches in an sich bekannter Weise in einer Kern/Mantel-Konstruktion vorliegt, gelöst, welches Seil dadurch gekennzeichnet ist, dass die spezifische Festigkeit des Seils F3 (in [daN/g Kern/m Seil]) in Abhängigkeit vom Durchmesser des Seils DM (in [mm]) folgender Formel genügt:This object is achieved by a rope made 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 3 (in [daN / g core / m Rope]) depending on the diameter of the rope DM (in [mm]) of the following formula:
F5 > 212 - DM.F 5 > 212 - DM.
Seile aus einem textilen Fasermaterial, welche in einer Kern/Mantel-Konstruktion vorliegen, sind an sich bekannt. Ein solches Seil besteht aus einem oder mehreren beispielsweise geflochtenen oder geschlagenen Kern(en) aus textilem Fasermaterial, welche(r) von einem textilen Fasermaterial als Mantel umhüllt, z.B . umflochten ist bzw. sind.Ropes of a textile fiber material, which are in a core / shell construction, are known per se. 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 as a sheath envelops, for. is braided or are.
Für die Zwecke der vorliegenden Erfindung steht im folgenden der Begriff „Kern" sowohl für einen einzigen Kern als auch für eine Mehrzahl von in einem Seil vorhandenen Kernen.For the purposes of the present invention, the term "core" will be understood hereinafter to mean both a single core and a plurality of cores present in a cable.
Seile mit einer Kern/Mantel-Konstruktion sind zwar für viele Gebiete, wie z.B. im Bereich des Bergsportes oder der Nautik, gebräuchlich, wurden aber für den Bereich von Seilgeräten in der Land- und Forstwirtschaft bislang nicht vorgeschlagen. Dafür gibt es verschiedene Gründe:Although ropes having a core / shell construction are suitable for many areas, such as e.g. in the field of mountain sports or nautical, in use, but have not yet been proposed for the field of ropes in agriculture and forestry. There are several reasons for that:
Zum einen wirken im gegenständlichen Anwendungsbereich wesentlich höhere Zugbelastungen, die über den Mantel auf den Kern übertragen werden müssen. Selbst geringfügige Verschiebungen zwischen Kern und Mantel führen zu einer schlechten Kraftübertragung und zum Aufschieben des Mantels. Dadurch wird das Seil für Abrasion anfallig und weist zudem an der entsprechenden Stelle eine Verdickung auf, die noch stärker beansprucht wird. All dies führt schlussendlich zur Zerstörung des Seils.On the one hand, much higher tensile loads act in the objective field of application, which must be transmitted to the core via the jacket. Even slight shifts between the core and the jacket lead to poor power transmission and the sliding of the jacket. As a result, the rope is prone to abrasion and also has at the appropriate location on a thickening, which is even more stressed. All this eventually leads to the destruction of the rope.
Die Erfindung stellt nun erstmals ein textiles Seil mit Kern-/Mantelstruktur zur Verfügung, welches ähnlich gute Zugfestigkeiten und Abrasionsbeständigkeit wie ein Stahlseil vergleichbarer Dicke aufweist.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.
Der Durchmesser DM des erfindungsgemäßen Seils beträgt dabei bevorzugt 4 bis 60 mm, bevorzugt 4 bis 40 mm, insbesondere bevorzugt 4 bis 26 mm. Bevorzugt ist der Kern des erfindungsgemäßen Seiles in einem Ausmaß von mehr als 5%, bevorzugt 5,5% bis 20%, besonders bevorzugt 6% bis 15% der Höchstzugskraft des Kerns, verstreckt. Der Kern von herkömmlichen Seilen mit einer Kern-/Mantel-Konstruktion ist üblicherweise nur bis zu einem Bereich von bis zu 5% der Höchstzugskraft verstreckt.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. Preferably, the core of the rope according to the invention is stretched to an extent of more than 5%, preferably 5.5% to 20%, particularly 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.
Es hat sich dabei als günstig erwiesen, wenn die Verstreckung des Kerns einer bei gegenüber Raumtemperatur erhöhten Temperatur, insbesondere bei einer Umgebungstemperatur bis hin zum Schmelzbereich bzw. Zersetzungsbereich des jeweils als Fasermaterial des Kerns verwendeten Polymers durchgeführt wird. Die für das jeweilige Fasermaterial des Kerns geeigneten Temperaturbereiche kann der Fachmann im Rahmen seines Fachwissens ermitteln. Bei Kernen aus einem HMPE-Fasermaterial (z.B. Dyneema®-Fasern) ist eine Umgebungstemperatur von 50°C bis 1400C, bevorzugt von 90°C bis 120°C, bevorzugt.It has proven to be advantageous if 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. For nuclei of a HMPE fiber material (eg, Dyneema® fibers) is an ambient temperature of 50 ° C to 140 0 C, preferably from 90 ° C to 120 ° C, preferably.
Der Durchmesser eines erfmdungsgemäß bevorzugt hoch verstreckten Kerns ist gegenüber weniger verstreckten Kernen verkleinert. Dadurch wird ermöglicht, trotz Aufbringung eines Mantels auf den Kern ein Seil zu erhalten, welches nicht wesentlich dicker ist als ein Stahlseil gleicher Zugfestigkeit. Gleichzeitig gewährleistet der Mantel gegenüber einem ausschließlich aus einem Kern aus hochfesten Fasern bestehenden Seil einen Schutz des Kerns und eine verbesserte Abriebbeständigkeit.The diameter of a preferably highly stretched core according to the invention is reduced in size compared to 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.
Aufgrund der erfindungsgemäß bevorzugten hohen Verstreckung des Kerns des Seils tritt außerdem bei der Anwendung des Seiles keine weitere Durchmesserverringerang des Kerns auf. Dadurch kann eine Verschiebung zwischen Mantel und Kern weitgehend unterbunden werden.Due to the inventively preferred high stretching of the core of the rope also occurs in the application of the rope no further Durchmesserverringerang of the core. As a result, a shift between shell and core can be largely prevented.
Bevorzugt ist das Fasermaterial des Kerns aus der Gruppe bestehend aus hochfesten Fasern, insbesondere hochfesten Hochmodul-Polyethylenfasern, Aramidfasern, Flüssigkristallin(LC-)Polyesterfasern, Polybenzoxazolfasern sowie Mischungen daraus ausgewählt.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.
Hochfeste Hochmodul-Polyethylenfasern sind unter der Markenbezeichnung Dyneema® kommerziell erhältlich. LC-Polyesterfasern sind unter dem Markennamen Vectran® kommerziell erhältlich.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®.
Ebenfalls bevorzugt ist das Fasermaterial des Mantels aus der Gruppe bestehend aus hochabriebfesten Fasern, insbesondere hochfesten Hochmodul-Polyethylenfasern, Flüssigkristallin(LC-)Polyesterfasern, sonstigen abriebfesten Polyesterfasern, Polyamidfasern und Mischungen daraus ausgewählt.Also preferred is 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.
Das erfindungsgemäße Seil weist bevorzugt Mittel zur Erhöhung der Haftung zwischen Kern und Mantel des Seils auf.The rope according to the invention preferably has means for increasing the adhesion between core and sheath of the rope.
Dazu kann zumindest ein Teil der Oberfläche des Kerns mit einem Material ausgewählt aus der Gruppe bestehend aus Stapelfasergarnen und texturierten Multifilamentgarnen umhüllt sein. Diese Umhüllung kann beispielsweise in an sich bekannter Weise in Form einer Bewehrung, einer Umflechtung oder in Form von mit dem Kern mitgeflochtenen und zumindest teilweise an dessen Oberfläche liegenden Fasern mit erhöhter Haftung vorliegen.For this purpose, 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.
Als Material für die Umhüllung eignen sich insbesondere Polyamid, Polyester, Polyacrylat, Polypropylen, Polyethylen sowie Mischungen daraus.Polyamide, polyester, polyacrylate, polypropylene, polyethylene and mixtures thereof are particularly suitable as material for the covering.
Zur Erhöhung der Haftung zwischen Kern und Mantel können zwischen diesen Komponenten Vernähungen vorgesehen werden.To increase the adhesion between the core and the jacket, sutures can be provided between these components.
Alternativ oder zusätzlich zu den bereits erwähnten Möglichkeiten der Haftungserhöhung zwischen Kern und Mantel kann zumindest ein Teil der Oberfläche des Kerns mit einer haftungserhöhenden Substanz beschichtet sein.Alternatively or in addition to the already mentioned possibilities of increasing the adhesion between the core and the jacket, at least part of the surface of the core may be coated with an adhesion-enhancing substance.
Auch der Mantel selbst bzw. die den Mantel bildenden Seilelemente wie z.B. Garne oder Zwirne kann/können mit einer haftungserhöhenden Substanz beschichtet sein.Also, the jacket itself or the cable elements forming the sheath such. Yarns or threads may be coated with an adhesion-enhancing substance.
Das erfindungsgemäße Seil bietet mehrere Möglichkeiten zur Feststellung von Schäden, aufgrund welcher das Seil als ablegereif angesehen muss:The rope according to the invention offers several possibilities for detecting damage, on the basis of which the rope must be considered as ready for storage:
So können anhand einer Überprüfung des Zustandes des Mantels Schäden am Seil einfach festgestellt werden: Sobald Teile des Kernes sichtbar werden, muss das Seil ersetzt werden.Thus, by checking the condition of the jacket damage to the rope can be easily determined: As soon as parts of the core become visible, the rope must be replaced.
Indizien für eine Ermüdung des Kernes eines Seiles sind einerseits eine Verdünnung des Seiles bzw. andererseits eine Verlängung des Seiles.Indications for a fatigue of the core of a rope are on the one hand a dilution of the rope or on the other hand an extension of the rope.
Beim erfindungsgemäßen Seil geht eine Verdünnung des Seiles mit einer Lockerung des Mantels einher, welche manuell festgestellt werden kann. In einer bevorzugten Ausfuhrungsform des erfindungsgemäßen Seiles weist der Mantel Markierungen auf, anhand welcher eine Verlängung des Seiles und/oder eine Verdrehung des Seiles feststellbar ist.When the rope according to the invention a dilution of the rope is associated with a relaxation of the jacket, which can be manually detected. In a preferred embodiment of the rope according to the invention, the jacket has markings on the basis of which an elongation of the rope and / or a twist of the rope can be detected.
Die Markierungen können beispielsweise fix beabstandet sein. Wenn der Mantel fix beabstandete Markierungen (z.B. einzelne anders gefärbte Flechtrauten in einem fixen Abstand von jeweils z.B. 10 cm) enthält, so kann vor Benutzung des Seiles überprüft werden, ob sich dieser Abstand geändert, insbesondere verlängert hat, was auf eine Verlängung des Seiles und daher auf eine Ablegereife hindeutet.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.
Ebenso ist mit einem Muster von Markierungen (z.B. Streifenmuster oder sonstige Markierungen in Längsrichtung des Seiles) feststellbar, ob sich das Seil beim Gebrauch verdreht hat, was anhand einer Verzerrung des ursprünglichen Musters feststellbar ist. Eine Verdrehung des Seiles ist ungünstig und verringert die Zugfestigkeit des Seiles signifikant. Daher ist ein Zurückdrehen in die ursprüngliche, d.h. verdrehungsfreie Form des Seiles notewendig.Likewise, with a pattern of markings (e.g., stripe patterns or other markings along the length of the rope), it can be determined whether the rope has twisted during use, which is detectable by distortion of the original pattern. 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.
Das erfindungsgemäße Seil eignet sich besonders zum Einsatz in Seilgeräten, insbesondere im Bereich der Land- und Forstwirtschaft und der Bau- und Transportwirtschaft. Mit dem erfindungsgemäßen Seil kann erstmals eine gleichwertige Alternative zu Stahlseilen, allerdings bei viel geringerem Gewicht (ein erfindungsgemäßes Seil hat typischerweise ein Gewicht von lediglich etwa 20% des Gewichts eines vergleichbaren Stahlseils) zur Verfügung gestellt werden.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. With the rope according to the invention, 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.
Insbesondere eignet sich das erfindungsgemäße Seil als Tragseil, Abspannseil, Zugseil, Hubseil, Rückholseil oder Rückeseil in Seilgeräten, Mastseilgeräten und Winden gemäß den beispielsweise in den Ö-Normen L 5219 und L 5276 hinsichtlich mobiler Seilgeräte zur Holzbringung bzw. Rückewinden für die Land- und Forstwirtschaft verwendeten Definitionen.In particular, 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 Ö standards L 5219 and L 5276 in terms of mobile ropes for wood handling or Rückewinden for land and Forestry used definitions.
