Definitions
- the invention relates to a textile lifting sling according to the preamble of claim 1.
- lifting straps are the subject of DIN 61360, March 1986, Part 1 (terms, dimensions, attachment types) and Part 2 (safety requirements and testing) .
- reinforcements on the lifting sling are additional equipment that is firmly connected to the lifting sling, for example by sewing.
- the invention is particularly concerned with such lifting straps as they are in the systematic overview of the lifting strap shapes and designs on page 3 of DIN 61360, part 1, the versions 2N (woven, with reinforcement) and 4N (laid with reinforcement) and the Form B (with loops) are assigned.
- These reinforcements serve as abrasion protection, particularly in the area of the highly stressed lifting strap areas, e.g. in the end loops.
- a band of textile material sewn on in the particularly stressed areas is used as wear protection.
- a reinforcement strap around the entire lifting strap in the end loop area and to sew it to the lifting strap.
- the sewn-on reinforcement in the end loop area has the further task of reducing the effective bandwidth to up to 1/3 of the bandwidth in the work surface area.
- This width reduction in the end loop area is carried out by folding (doubling) the lifting strap with at least its one side edge around an axis running in the longitudinal direction of the strap. In this folded condition, the reinforcement is placed around the end loop area of the lifting strap and sewn to it.
- the reinforcement there has the further function of permanently maintaining the bandwidth reduction in the end loop area.
- the aforementioned standard prescribes that the same material as the belt strap or other suitable material is used for the reinforcements, particularly in the end loops. It is common to use a belt fabric for the reinforcements, which is connected to the lifting belt as a textile cover.
- the invention has for its object to provide a lifting strap of the type mentioned with improved abrasion protection in the end loop area and / or in the work surface area.
- the object is solved by claim 1.
- the textile cover used as abrasion protection has in its connection area with the lifting strap the extensibility or flexibility described above as advantageous and thus also a configuration which favors the connection process. Between the connection areas, however, the textile cover is designed in such a way that it can better meet the task of protecting it from abrasion.
- the necessary, heterogeneous structure of the textile covering is easy to manufacture by being a band fabric with warp threads running in the longitudinal direction of the lifting band. As a result, the zones of different wear resistance located in different band width ranges can be achieved simply by a corresponding choice and arrangement of the warp threads of the band fabric.
- a greater strip thickness or thickness can be selected in the zones of increased wear resistance by using stronger warp threads or a greater number of warp threads there than in the zones of lower wear resistance, namely in the connection areas.
- Claims 2 and 3 propose sewing to connect the textile support with the lifting strap.
- the sewing can be carried out in a technically simple manner and ensures a long service life of the connection between the textile cover and the lifting strap.
- the textile reinforcement for its connection or seam areas is provided with textile grooves running in the warp direction.
- the zones designed as fabric grooves are an effective protection of the connection between the textile cover and the lifting strap against damage and destruction.
- the connecting seams are not destroyed by the mechanical loads on the lifting belt surface due to frictional forces.
- the width zones of increased abrasion resistance located outside the textile grooves are positioned in the finished lifting sling in such a way that they form either an edge protector or a surface protector for the stressed surfaces both in the worktop area and in the end loop area.
- the lifting strap 1 shown in FIG. 1 essentially contains its work surface area 4 located between the two end loops 2, 3. At the two ends of the work surface area 4 there is an end loop area 6 and 7 on both sides in the belt longitudinal direction 5.
- the longitudinal direction 5 corresponds to the warp thread direction.
- the lifting strap - not shown in the figures - is a laid belt strap, the strap longitudinal direction 5 corresponds to the longitudinal direction of the laid scrim.
- the woven belt strap forming the supporting part of the lifting strap 1 is provided with the reference number 8.
- the webbing 8 is at least partially covered in the work surface area 4 and / or in the end loop areas 6, 7 by a textile reinforcement 9 serving as abrasion protection.
- the non-load-bearing reinforcement 9 can completely surround the webbing 8 in the direction of the bandwidth 10 (FIGS. 2a, b).
- the reinforcement 9 can also be designed such that it only partially surrounds the webbing 8, in particular in the region of its edges 11, 12 (FIGS. 2c, 4). Then there are usually two reinforcements 9 in the respective length range of the lifting strap 1.
- the cross section of the webbing 8 is not shown in detail in the figures. This principle therefore applies not only to the design of the lifting sling in the end loop area 6,7 but also in the work surface area 4, where there is generally a larger effective belt strap width than in the end loop area 6,7.
- an effective reduction in the bandwidth in the direction of the bandwidth 10 is achieved in that the webbing 8 there about at least one of its two edges 11, 12 for a doubling (or Tripling) the effective belt strap is put around.
- the reinforcement 9 consists of a belt fabric with zones 14-17 adjacent to one another in the width direction 10 of increased wear resistance. At least on one flank of these zones or between these zones are zones 18, 19 of reduced wear resistance.
- the tape fabric used as reinforcement 9 is designed so that its warp threads run in the longitudinal direction 5 of the tape in the sewn state. Accordingly, the weft direction of the textile support corresponds to the width direction 10.
- the zones 14-17 of increased wear resistance are formed by the fact that warp threads of greater material thickness or in a greater density are present there.
- the zones 18, 19 of reduced wear resistance in particular in the sewn state, have the shape of a fabric groove, the surfaces 21 of which are recessed relative to the surfaces 22 of the zones 14-17 of increased wall thickness 20.
- This recessed position serves to protect the connecting seams 23 between the reinforcement 9 as a protective element and the webbing 8 as a supporting element. Even a strong abrasion load on the surfaces 22 of the zones 14-17 of greater wear resistance does not result in any abrasion load on the connecting seams 23. Because of the seam guidance which is targeted in the region of the zones 18, 19 of lower wear resistance, the expansion properties of the reinforcement 9 or of the abrasion protection remain unaffected.
- the positioning of the different zones 14-19 of the reinforcement 9 in the form of the inevitable relief formation of the surfaces 21,22 is also unmistakable for the person employed in production, so that the configuration of the reinforcement 9 according to the invention implies a sewing instruction to a certain extent.
- the reinforcement 9 according to the invention can be bent more easily in the zones 18, 19 of lower wear resistance about an axis parallel to the longitudinal axis 13 of the belt, so that handling in production is not impaired by zones 14-17 of increased wear resistance.
- the reinforcement 9 according to the invention can also be used with endless lifting straps 1 designed in the form of a loop.
Abstract
Description
Die Erfindung betrifft ein textiles Hebeband nach dem Oberbegriff des Anspruches 1.The invention relates to a textile lifting sling according to the preamble of claim 1.
Solche Hebebänder sind Gegenstand von DIN 61360, März 1986, Teil 1 (Begriffe, Maße, Anschlagarten) und Teil 2 (sicherheitstechnische Anforderungen und Prüfung). Danach sind definitionsgemäß Verstärkungen am Hebeband zusätzliche Ausrüstungen, die mit dem Hebeband fest, z.B. durch Nähen, verbunden sind.Such lifting straps are the subject of DIN 61360, March 1986, Part 1 (terms, dimensions, attachment types) and Part 2 (safety requirements and testing) . According to this definition, reinforcements on the lifting sling are additional equipment that is firmly connected to the lifting sling, for example by sewing.
Die Erfindung befaßt sich insbesondere mit solchen Hebebändem, wie sie in der systematischen Übersicht der Hebeband-Formen und -Ausführungen auf S. 3 von DIN 61360, Teil 1 den Ausführungen 2N (gewebt, mit Verstärkung) und 4N (gelegt mit Verstärkung) und der Form B (mit Schlaufen) zugeordnet sind. Diese Verstärkungen dienen als Abriebschutz insbesondere im Bereich der hochbeanspruchten Hebebandbereiche, z.B. in den Endschlaufen.The invention is particularly concerned with such lifting straps as they are in the systematic overview of the lifting strap shapes and designs on
Herkömmlich wird als Abriebschutz ein in den besonders beanspruchten Bereichen aufgenähtes Band aus textilem Werkstoff verwendet. Beispielsweise ist es bekannt, im Endschlaufenbereich ein solches Verstärkungsband um das gesamte Hebeband herumzulegen und mit dem Hebeband zu vernähen. Insbesondere bei relativ breiten Hebebändern hat im Endschlaufenbereich die aufgenähte Verstärkung die weitere Aufgabe, die wirksame Bandbreite auf bis zu 1/3 der Bandbreite im Arbeitsflächenbereich zu reduzieren. Diese Breitenreduktion im Endschlaufenbereich wird dadurch vorgenommen, daß dort das Hebeband mit mindestens seiner einen Seitenkante um eine in Bandlängsrichtung verlaufende Achse umgelegt (gedoppelt) wird. In diesem umgelegten Zustand wird die Verstärkung um den Endschlaufenbereich des Hebebandes herumgelegt und mit ihm vernäht. Dadurch hat dort die Verstärkung die weitere Funktion, die Bandbreitenverringerung im Endschlaufenbereich dauerhaft aufrechtzuerhalten.Conventionally, a band of textile material sewn on in the particularly stressed areas is used as wear protection. For example, it is known to place such a reinforcement strap around the entire lifting strap in the end loop area and to sew it to the lifting strap. Especially with relatively wide lifting straps, the sewn-on reinforcement in the end loop area has the further task of reducing the effective bandwidth to up to 1/3 of the bandwidth in the work surface area. This width reduction in the end loop area is carried out by folding (doubling) the lifting strap with at least its one side edge around an axis running in the longitudinal direction of the strap. In this folded condition, the reinforcement is placed around the end loop area of the lifting strap and sewn to it. As a result, the reinforcement there has the further function of permanently maintaining the bandwidth reduction in the end loop area.
Die genannte Norm schreibt vor, daß für die Verstärkungen insbesondere in den Endschlaufen ein gleicher Werkstoff wie das Gurtband oder anderes geeignetes Material verwendet wird. So ist es üblich, für die Verstärkungen ein Bandgewebe zu benutzen, welches als Textilauflage mit dem Hebeband verbunden wird.The aforementioned standard prescribes that the same material as the belt strap or other suitable material is used for the reinforcements, particularly in the end loops. It is common to use a belt fabric for the reinforcements, which is connected to the lifting belt as a textile cover.
Für eine dauerhafte Fixierung der Verstärkungen auf dem Hebeband ist es zweckmäßig, daß ihre textile Struktur im Verbindungsbereich mit dem Hebeband ausreichend dehnfähig und damit der im Gebrauch zu erwartenden Hebebanddehnung angepaßt ist. Diese Anforderungen an die Dehnfähigkeit des Verstärkungsgewebes und auch der Verbindung mit dem Hebeband steht aber in einem gewissen Gegensatz zu der Funktion als Abriebschutz. Eine gute Dehnbarkeit und auch eine gute Handhabbarkeit der Verstärkung bei ihrer Verbindung mit dem Hebeband sowie die Vermeidung einer im Gebrauch schädlichen Faltenbildung erfordem eine Begrenzung auch der Wandstärke des Verstärkungsgewebes. Eine solche Wandstärkenbeschränkung indessen beeinträchtigt die Dauerhaftigkeit und Wirksamkeit als Abriebschutz.For a permanent fixation of the reinforcements on the lifting sling, it is expedient that their textile structure in the connection area with the lifting sling is sufficiently stretchable and thus adapted to the lifting sling expansion to be expected in use. However, these requirements for the elasticity of the reinforcing fabric and also the connection with the lifting strap stand in a certain contrast to the function as abrasion protection. A good elasticity and also a good handling of the reinforcement when it is connected to the lifting strap, as well as the avoidance of wrinkling that is harmful in use, also require a limitation of the wall thickness of the reinforcing fabric. Such a wall thickness limitation, however, affects durability and effectiveness as wear protection.
Der Erfindung liegt die Aufgabe zugrunde, ein Hebeband der eingangs genannten Art mit einem verbesserten Abriebschutz im Endschlaufenbereich und/oder im Arbeitsflächenbereich zu schaffen. Die Aufgabe wird durch Anspruch 1 gelöst.The invention has for its object to provide a lifting strap of the type mentioned with improved abrasion protection in the end loop area and / or in the work surface area. The object is solved by claim 1.
Die Wirkung des Erfindungsgegenstandes kann kurz wie folgt beschrieben werden. Die als Abriebschutz verwendete Textilauflage weist in ihrem Verbindungsbereich mit dem Hebeband die vorstehend als vorteilhaft geschilderte Dehnbarkeit bzw. Flexibilität und damit auch eine den Verbindungsvorgang begünstigende Ausgestaltung auf. Zwischen den Verbindungsbereichen indessen ist die Textilauflage so ausgestaltet, daß sie der ihr obliegenden Aufgabe des Abriebschutzes besser entsprechen kann. Die dazu notwendige, heterogene Struktur der Textilauflage ist einfach herstellbar, indem sie ein Bandgewebe mit in Hebebandlängsrichtung verlaufenden Kettfäden ist. Dadurch können die in unterschiedlichen Bandbreitenbereichen befindlichen Zonen unterschiedlicher Verschleißfestigkeit einfach durch eine entsprechende Wahl und Anordnung der Kettfäden des Bandgewebes erzielt werden. Beispielsweise kann in den Zonen erhöhter Verschleißfestigkeit eine größere Banddicke bzw. -stärke gewählt werden, indem dort stärkere Kettfäden oder eine größere Anzahl von Kettfäden als in den Zonen geringerer Verschleißfestigkeit, nämlich in den Verbindungsbereichen verwendet werden. Diese Gestaltungsformen lassen sich einfach innerhalb der in der genannten Norm für die Werkstoffwahl gesetzten Grenzen bewerkstelligen (DIN 61360, März 1986, Teil 2, 2.1 "Werkstoffe").The effect of the subject of the invention can be briefly described as follows. The textile cover used as abrasion protection has in its connection area with the lifting strap the extensibility or flexibility described above as advantageous and thus also a configuration which favors the connection process. Between the connection areas, however, the textile cover is designed in such a way that it can better meet the task of protecting it from abrasion. The necessary, heterogeneous structure of the textile covering is easy to manufacture by being a band fabric with warp threads running in the longitudinal direction of the lifting band. As a result, the zones of different wear resistance located in different band width ranges can be achieved simply by a corresponding choice and arrangement of the warp threads of the band fabric. For example, a greater strip thickness or thickness can be selected in the zones of increased wear resistance by using stronger warp threads or a greater number of warp threads there than in the zones of lower wear resistance, namely in the connection areas. These design forms can be easily accomplished within the limits set in the aforementioned standard for the choice of materials (DIN 61360, March 1986, Part 2, 2.1 "Materials").
Anspruch 2 und 3 schlagen zur Verbindung der Textilauflage mit dem Hebeband eine Vernähung vor. Die Vernähung kann technisch einfach bewerkstelligt werden und gewährleistet eine lange Lebensdauer der Verbindung von Textilauflage und Hebeband.
Durch die Nahtführung gemäß Anspruch 3 bleiben die Dehnungseigenschaften der Textilauflage unbeeinflußt.Due to the seam guide according to
Gemäß Anspruch 6 ist die textile Verstärkung für ihre Verbindungs- oder Nahtbereiche mit in Kettrichtung verlaufenden textilen Nuten versehen. Die als Gewbenuten ausgebildeten Zonen sind ein wirksamer Schutz der Verbindung zwischen Textilauflage und Hebeband vor Beschädigungen und Zerstörungen. So können z.B. die Verbindungsnähte bei der mechanischen Belastung der Hebebandoberfläche durch Reibungskräfte nicht zerstört werden.According to claim 6, the textile reinforcement for its connection or seam areas is provided with textile grooves running in the warp direction. The zones designed as fabric grooves are an effective protection of the connection between the textile cover and the lifting strap against damage and destruction. For example, the connecting seams are not destroyed by the mechanical loads on the lifting belt surface due to frictional forces.
Die außerhalb der textilen Nuten befindlichen Breitenzonen erhöhter Abriebfestigkeit sind beim fertigen Hebeband so positioniert, daß sie entweder einen Kantenschutz oder einen Flächenschutz der beanspruchten Flächen sowohl im Arbeitsflächenberelch als auch im Endschlaufenbereich bilden.The width zones of increased abrasion resistance located outside the textile grooves are positioned in the finished lifting sling in such a way that they form either an edge protector or a surface protector for the stressed surfaces both in the worktop area and in the end loop area.

Das in Fig. 1 dargestellte Hebeband 1 enthält im wesentlichen seinen zwischen den beiden Endschlaufen 2,3 befindlichen Arbeitsflächenbereich 4. An die beiden Enden des Arbeitsflächenbereiches 4 schließt sich in Bandlängsrichtung 5 beidseitig ein Endschlaufenbereich 6 bzw. 7 an.The lifting strap 1 shown in FIG. 1 essentially contains its
Soweit das Hebeband 1 aus einem gewebten Gurtband als tragendes Teil besteht, entspricht die Bandlängsrichtung 5 der Kettfadenrichtung. Soweit das Hebeband - in den Figuren nicht dargestellt - ein gelegtes Gurtband ist, entspricht die Bandlängsrichtung 5 der Längsrichtung des Fadengeleges.As far as the lifting strap 1 consists of a woven webbing as a supporting part, the
In den Figuren ist das den tragenden Teil des Hebebandes 1 bildende gewebte Gurtband mit der Bezugsziffer 8 versehen. Das Gurtband 8 ist im Arbeitsflächenbereich 4 und/oder in den Endschlaufenbereichen 6,7 mindestens teilweise von einer als Abriebschutz dienenden, textilen Verstärkung 9 abgedeckt. Die nichttragende Verstärkung 9 kann das Gurtband 8 in Bandbreitenrichtung 10 vollständig umgeben (Fig. 2a,b). Die Verstärkung 9 kann aber auch so ausgebildet sein, daß sie das Gurtband 8 nur partiell, insbesondere im Bereich seiner Kanten 11,12 umgibt (Fig. 2c,4). Dann sind in der Regel zwei Verstärkungen 9 im jeweiligen Längenbereich des Hebebandes 1 vorhanden.In the figures, the woven belt strap forming the supporting part of the lifting strap 1 is provided with the
In den Figuren ist der Querschnitt des Gurtbandes 8 nicht im einzelnen dargestellt. Daher gilt diese Darstellung vom Prinzip her nicht nur für die Hebebandgestaltung im Endschlaufenbereich 6,7 sondern auch im Arbeitsflächenbereich 4, wo in aller Regel eine größere wirksame Gurtbandbreite vorliegt als im Endschlaufenbereich 6,7. Bereits in der Beschreibungseinleitung wurde darauf hingewiesen, daß im Endschlaufenbereich 6,7 eine wirksame Verringerung der Bandbreite in Bandbreitenrichtung 10 dadurch erzielt wird, daß dort das Gurtband 8 etwa um die Bandlängsachse 13 mit mindestens einer seiner beiden Kanten 11,12 zu einer Verdoppelung (oder Verdreifachung) der wirksamen Gurtbandstärker herumgelegt wird.The cross section of the
Die Verstärkung 9 besteht aus einem Bandgewebe mit in Bandbreitenrichtung 10 nebeneinanderliegenden Zonen 14-17 erhöhter Verschleißfestigkeit. Mindestens an einer Flanke dieser Zonen bzw. zwischen diesen Zonen befinden sich Zonen 18,19 verringerter Verschleißfestigkeit.The
Das als Verstärkung 9 verwendete Bandgewebe ist so gestaltet, daß seine Kettfäden in vemähtem Zustand in Bandlängsrichtung 5 verlaufen. Dementsprechend entspricht die Schußfadenrichtung der Textilauflage der Bandbreitenrichtung 10. Die Zonen 14-17 erhöhter Verschleißfestigkeit sind dadurch gebildet, daß dort Kettfäden von größerer Materialstärke oder in einer größeren Dichte vorhanden sind. Die Kettfäden bestehen normgemäß aus Polyester(= PES)-Stapelfaser oder -Multifilgarn, einer Aramidfaser o.dgl. Zur Erhöhung der Verschleißfestigkeit können auch höher verschleißfeste Qualitäten dieser Werkstoffe für das jeweilige Kettfadengarn verwendet werden. Vorteilhaft ist es, wenn die Zonen 14-17 erhöhter Verschleißfestigkeit gegenüber den Zonen 18,19 verringerter Verschleißfestigkeit eine vergrößerte Wandstärke 20 aufweisen. Dadurch weisen die Zonen 18,19 verringerter Verschleißfestigkeit insbesondere in vernähtem Zustand die Form einer Gewebenut auf, deren Oberflächen 21 gegenüber den Oberflächen 22 der Zonen 14-17 vergrößerter Wandstärke 20 vertieft liegen. Diese vertiefte Lage dient dem Schutz der Verbindungsnähte 23 zwischen der Verstärkung 9 als schützendem Element und dem Gurtband 8 als tragendem Element. Selbst eine starke Scheuerbelastung der Oberflächen 22 der Zonen 14-17 größerer Verschleißfestigkeit führt zu keiner Scheuerbelastung der Verbindungsnähte 23. Durch die im Bereich der Zonen 18,19 geringerer Verschleißfestigkeit gezielte Nahtführung bleiben die Dehnungseigenschaften der Verstärkung 9 bzw. des Abriebschutzes unbeeinflußt. Die Positionierung der unterschiedlichen Zonen 14-19 der Verstärkung 9 ist in Form allein der zwangsläufigen Reliefbildung der Oberflächen 21,22 auch für die in der Fertigung beschäftigte Person unübersehbar, so daß die erfindungsgemäße Ausgestaltung der Verstärkung 9 gewissermaßen eine Nähanleitung impliziert. Im übrigen läßt sich die erfindungsgemäße Verstärkung 9 in den Zonen 18,19 geringerer Verschleißfestigkeit leichter um eine zur Bandlängsachse 13 parallele Achse biegen, so daß die Handhabbarkeit in der Fertigung durch die Zonen 14-17 erhöhter Verschleißfestigkeit nicht beeinträchtigt ist.The tape fabric used as
Es sei erwähnt, daß die erfindungsgemäße Verstärkung 9 auch bei endlosen, in Form einer Schlinge ausgestalteten Hebebändern 1 verwendet werden kann.It should be mentioned that the
