Abstract

A lifting belt sling for lifting loads is comprised of a tubular structure having at least two chambers whereby forming, as one unit, a chamber tube that is contiguous over the width. Loosely inserted inserts are located inside the at least two chambers and endlessly extend from one end of the chamber tube to the other end thereof. The inserts overlap the ends of the chamber tube so that they form loops at this location, whereby the inserts, when situated in the loop area, are covered by a tube protective means. A protective tube, which surrounds the chamber tube and is formed by different weaves, significantly increases the resistance to abrasion, the resistance to cutting, and the edge strength. The lifting belt sling is designed for loads of up to 100 t.

Description

Die Erfindung betrifft eine Hebegurtschlinge gemäss Patentanspruch 1.The invention relates to a sling sling according to claim 1.

Rundschlingen werden vorwiegend in der Industrie, im Bauwesen und im Gewerbe für das Heben von Lasten eingesetzt. Hebegurten gelangen im Transportwesen und insbesondere in der Baubranche in vielfältige Weise zur Anwendung.Round slings are mainly used in industry, construction and trade for lifting loads. Lifting slings are used in transportation, and especially in the construction industry, in a variety of ways.

Nach der US 4,210,089 ist eine Rundschlinge bekannt, die zwei Kammern umfasst, um dadurch eine höhere Festigkeit und eine verbesserte Abrieb- und Schnittfestigkeit zu erhalten.After US 4,210,089 For example, a round sling is known which comprises two chambers to thereby obtain higher strength and improved abrasion and cut resistance.

Nach der US 5,238,278 ist eine textile Rundschlinge bekannt, mit zusätzlichen Rippen auf dem Rundschlingenschlauch, die dadurch eine verbesserte Schnitt- und Abriebfestigkeit bewirken sollen.After US 5,238,278 is a textile round sling known, with additional ribs on the Rundschlingenschlauch, which are intended to cause improved cut and abrasion resistance.

Nach der US 5,651,572 ist eine Rundschlinge bekannt, die einen zusätzlichen Strang von optischen Kabeln umfasst, um beim Bruch ein Signal auslösen zu können. Nach der US 4,843,807 ist eine Herstellungsmethode für eine Rundschlinge bekannt, die sich auf eine rationelle Herstellung einer Rundschlinge bezieht.After US 5,651,572 is known a round sling, which includes an additional strand of optical cables to trigger a signal at break. After US 4,843,807 is a production method for a round sling known, which refers to a rational production of a round sling.

Nach der US 5,498,047 ist eine Hebegurte bekannt, die aus einem gewebten Band besteht, mit Schlaufen und mindestens einer verstärkten Kante, die von frühzeitigem Verschleiss schützen soll. Bei der Verstärkung handelt es sich um eine zusätzliche Textileinlage.After US 5,498,047 is a sling known, which consists of a woven band, with loops and at least one reinforced edge, which is intended to protect against premature wear. The reinforcement is an additional textile insert.

In der US 5,727,833 wird eine Hebegurtschlinge gemäß dem Oberbegriff des Anspruchs 1 beschrieben, die aus einem schlauchartigen Gebilde mit zwei Kammern besteht, in denen sich Einlagen befinden. Diese Einlagen sind als endlose Schleifen so in den zwei Kammern geführt, dass jede Einlage der ersten Kammer sich auch in der zweiten Kammer wiederfindet, wodurch sich bezüglich der Mitte zwischen den beiden Kammern ein symmetrische Anordnung ergibt. Eine symmetrische Anordnung der Einlagen führt unter Belastung leicht zu einem Verdrehen der Hebegurtschlinge.In the US 5,727,833 a sling sling according to the preamble of claim 1 is described, which consists of a tubular structure with two chambers in which deposits are. These inserts are passed as endless loops in the two chambers, that each insert of the first chamber is also found in the second chamber, whereby a symmetrical arrangement results with respect to the center between the two chambers. A symmetrical arrangement of the inserts easily leads to a twisting of the sling under load.

Nachteilig bei den Rundschlingen und Hebegurten sind dabei die folgenden Punkte: Rundschlingen sind aus einem Schlauch gefertigt, der normalerweise aus einer Kammer besteht, aber auch - wie in US 4,210,089 ausgeführt - aus zwei Kammern bestehen kann. Rundschlingen werden aus endlosen Garnsträngen gefertigt, die immer einen runden, endlosen Ring oder Rundschlauch ergeben, die aber in der Dimension so ausgelegt werden können, dass sie Lasten bis zu 100 t heben können. Da Rundschlingen einen endlosen Ring ergeben, können sie nicht einfach unter einem stehenden Laststück durchgeführt werden.A disadvantage of the round slings and slings are the following points: Round slings are made of a tube, which usually consists of a chamber, but also - as in US 4,210,089 executed - can consist of two chambers. Round slings are made from endless strands of yarn, which always make a round, endless ring or round tube, but can be designed in the dimension so that they can lift loads up to 100 t. Because round slings an endless ring, they can not be easily performed under a standing load piece.

Hebegurten werden aus gewobenen Gurten gefertigt, die je nach Breite und Dicke normalerweise Lasten bis zu 20 t heben können. Hebegurten werden an einem Stück mit beidseitigen Schlaufen vernäht. Dieses Band kann unter einem stehenden Laststück durchgezogen und auf beiden Seiten mit den Schlaufen in einen Lasthaken eingehängt werden. Da die Bänder durch die Last unter starker Spannung stehen, sind diese sehr verschleiss- und schnittanfällig. Häufig wird versucht, diesen Nachteil mit einer aufwändigen Beschichtung zu beheben.Sling straps are made of woven straps that can normally lift loads of up to 20 t, depending on their width and thickness. Sling straps are sewn together in one piece with loops on both sides. This band can be pulled under a standing load piece and hooked on both sides with the loops in a load hook. Since the bands are under strong tension due to the load, they are very susceptible to wear and cuts. It is often attempted to remedy this disadvantage with a complex coating.

Es ist die Aufgabe der vorliegenden Erfindung, eine Hebegurtschlinge vorzuschlagen, bei der die Vorteile der Rundschlinge mit den Vorteilen der Hebegurte kombiniert werden.It is the object of the present invention to provide a sling, in which the advantages of the round sling are combined with the advantages of the slings.

Eine weitere Aufgabe besteht darin, die Service- und Gebrauchsdauer der Hebegurtschlinge gegenüber den herkömmlichen, aus Gurtmaterial vernähten Hebegurten wesentlich zu erhöhen und für Lasten bis zu 100 t auszulegen.Another object is to substantially increase service life and service life of the sling sling over conventional sling straps sewn from webbing material and designed for loads up to 100 tons.

Erfindungsgemäss wird diese Aufgabe mit einer Hebegurtschlinge gemäss dem Wortlaut nach Patentanspruch 1 gelöst.According to the invention this object is achieved with a sling according to the wording of claim 1.

Fig. 1 zeigt die Ansicht einer erfindungsgemässen Hebegurtschlinge. Die Hebegurtschlinge besteht aus einem schlauchartigen Gebilde 20, das mindestens zwei Kammern 2, 2' aufweist und so einen Kammernschlauch 1 bildet, der durch Enden 5, 5' begrenzt wird. Die Kammern werden im Herstellprozess gebildet und bestehen aus synthetischen Garnen, Geweben, Gewirken, gegossenem Kunststoff, extrudiertem synthetischem Material, Stahlgewebe oder chemisch beständigem Material, Leder oder synthetischem Leder. In den mindestens zwei Kammern 2, 2' befinden sich Einlagen 4, die endlos von einer Seite zur anderen Seite, bzw. vom einen Ende 5 zum anderen Ende 5', durch den Kammernschlauch 1 verlaufen, wobei die Einlagen asymmetrisch vorliegen, was später erläutert wird. Fig. 1 shows the view of an inventive sling sling. The sling sling consists of a tubular structure 20 which has at least two chambers 2, 2 'and thus forms a chamber tube 1, which is bounded by ends 5, 5'. The chambers are formed in the manufacturing process and consist of synthetic yarns, woven fabrics, knitted fabrics, molded plastic, extruded synthetic material, steel fabric or chemically resistant material, leather or synthetic leather. In the at least two chambers 2, 2 'are inserts 4, which extend endlessly from one side to the other side, or from one end 5 to the other end 5', through the chamber tube 1, wherein the deposits are asymmetrical, which will be explained later becomes.

Die Einlagen 4 bestehen aus Einzelfasern oder Fasernbündel von hochfesten Materialien wie Polyester (PES), Polyamid (PA), Polypropylen (PP), Polyethylen (PE), Dyneema, Kevlar und Stahllitzen. Sie werden auch als Zugeinlagen bezeichnet, da sie im Wesentlichen die gesamte Belastung aufnehmen, während der sie umgebende Kammernschlauch 1 unter Zug im Wesentlichen unbelastet bleibt und vor allem eine Schutzfunktion ausübt. Dadurch ergibt sich eine wesentlich längere Lebensdauer der Hebegurtschlinge. Ebenfalls können die Einlagen oder der Schutzschlauch aus einer Kombination dieser Materialien bestehen, bzw. als Mischbündel von Einlagefasern vorliegen.The inserts 4 consist of single fibers or fiber bundles of high-strength materials such as polyester (PES), polyamide (PA), polypropylene (PP), polyethylene (PE), Dyneema, Kevlar and steel strands. They are also referred to as traction inlays, since they essentially absorb the entire load, while the chamber tube 1 surrounding them remains essentially unloaded under tension and above all exercises a protective function. This results in a much longer life of the sling sling. Also, the inserts or the protective tube may consist of a combination of these materials, or be present as a mixed bundle of insert fibers.

Die Einlagen 4 überragen, bzw. überlappen die Enden 5, 5' des Kammernschlauches 1, sodass dort Schlaufen 3, 3' gebildet werden. Die Einlagen sind im Schlaufenbereich durch einen Schlaufenschutz 6, 6' abgedeckt, der den Kammernschlauch 1 in der Regel überlappt und mit diesem verbunden ist. Er kann aber auch gestossen an den Enden 5, 5' des Kammernschlauches 1 ohne Verbindung anliegen (nicht dargestellt). Der Kammernschlauch kann aus unterschiedlichen Materialien bestehen, mit diesen abgedeckt oder beschichtet sein. Als Materialien kommen synthetische und natürliche Materialien wie Polyurethan, synthetischer Gummi, natürlicher Gummi, PVC, Textilstoffe, Vliessstoffe, synthetisches Leder, Leder, Stahllitzengewebe, Garngewebe und Garngewirke in Frage. Die so in den Kammernschlauch 1 eingeführten Einlagen 4 und endlos durch den Kammernschlauch zurückgeführten Einlagen bilden mit den an beiden Enden 5, 5' gebildeten Schlaufen 3, 3' ein Band mit endlosen Einlagen. Die Schlaufen können durch verschiedene Schutzmaterialien abgedeckt vorliegen, z.B. als Gewebe oder als Schlauch.The inserts 4 project beyond, or overlap the ends 5, 5 'of the chamber tube 1, so that loops 3, 3' are formed there. The inserts are covered in the loop area by a loop protection 6, 6 ', which overlaps the chamber tube 1 in the rule and is connected thereto. However, it can also abut the ends 5, 5 'of the chamber tube 1 without connection (not shown). The chamber tube can be made of different materials, with these covered or coated. Suitable materials are synthetic and natural materials such as polyurethane, synthetic rubber, natural rubber, PVC, textiles, nonwovens, synthetic leather, leather, steel stranded fabric, yarn and knitted fabric. The inserted so in the chamber tube 1 inserts 4 and endlessly returned through the chamber tube deposits form with the at both ends 5, 5 'formed loops 3, 3' a band with endless deposits. The loops may be covered by various protective materials, eg as a fabric or as a hose.

Fig. 2 zeigt eine perspektivische Schnitt-Ansicht einer Hebegurtschlinge. Erkennbar ist der Kammernschlauch 1 mit seinem einen Ende 5 und den Kammern 2, 2', denen vier weitere Kammern angereiht sind. In den Kammern befinden sich die Einlagen 4. Die mindestens zwei Kammern 2, 2' sind durch Vernähen, Verwirken oder Verweben entstanden. So weisen die Kammern z.B. Nähte auf, die in der Zugrichtung parallel zu den Einlagen liegen, wodurch der Kammernschlauch in Kammern aufgeteilt vorliegt. Solche Hebegurtschlingen werden vorwiegend für Anwendungen in der Maschinenindustrie, im Baugewerbe, für die Transport- und die Güterindustrie eingesetzt, wie dies z.B. auf Güterumschlagplätzen jeglicher Art der Fall ist. Fig. 2 shows a perspective sectional view of a sling sling. Visible is the chamber tube 1 with its one end 5 and the chambers 2, 2 ', which are lined up four further chambers. The deposits 4 are located in the chambers. The at least two chambers 2, 2 'have been created by sewing, forking or weaving. For example, the chambers have seams that are parallel to the inserts in the pulling direction, whereby the chamber tube is divided into chambers. Such sling loops are mainly used for applications in the machine industry, construction industry, for the transport and the goods industry, as is the case for example on freight hubs of any kind.

Fig. 3 zeigt eine perspektivische Schnitt-Ansicht einer Hebegurtschlinge mit Kammern geringer Breite und grosser Dicke. In den Kammern 2, 2' des Kammernschlauches 1 sind die Zugeinlagen 4 so angeordnet, dass die Kammern eine geringe Breite bei einer grossen Dicke aufweisen. Fig. 3 shows a perspective sectional view of a sling sling with chambers of small width and large thickness. In the chambers 2, 2 'of the chamber tube 1, the tensile inserts 4 are arranged so that the chambers have a small width with a large thickness.

Diese Gurten sind vor allem für die Hebung von grossen Lasten geeignet und werden für Lasten bis 100 t bei einem Sicherheitsfaktor von 7 : 1 hergestellt. Solche Hebegurtschlingen finden Anwendungen im Turbinenbau, für Schwerlasten in Kraftwerken oder der Industrie im allgemeinen.Above all, these straps are suitable for lifting large loads and are manufactured for loads up to 100 t with a safety factor of 7: 1. Such sling loops find applications in turbine construction, for heavy loads in power plants or industry in general.

Fig. 4 zeigt eine perspektivische Schnitt-Ansicht einer Hebegurtschlinge mit Kammern grosser Breite und geringer Dicke. In den Kammern 2, 2' des Kammernschlauches 1 sind die Zugeinlagen 4 so angeordnet, dass die Kammern eine grosse Breite bei einer geringer Dicke aufweisen. Solche Hebegurtschlingen gelangen vor allem zum Einsatz wenn wenig Raum zur Verfügung steht, um die Hebegurtschlingen unter die Last zu schieben. Der Kammernschlauch kann so einen Querschnitt aufweisen, der bezüglich Dicke, Breite und Tragkraft frei nach den Anwendungsbedürfnissen ausgelegt ist. Fig. 4 shows a perspective sectional view of a sling sling with chambers of large width and small thickness. In the chambers 2, 2 'of the chamber tube 1, the tensile inserts 4 are arranged so that the chambers have a large width at a small thickness. Such sling loops are mainly used when there is little space to the sling loops under the load slide. The chamber tube may thus have a cross-section which is freely designed in terms of thickness, width and load capacity according to the application needs.

Fig. 4A zeigt eine Hebegurtschlinge mit asymmetrischen Einlagen. Die im Kammernschlauch 1 lose eingelegten Einlagen 4 sind hier gestrichelt angedeutet. Die Einlage 4' in der äusseren Kammer der einen Seite des Kammernschlauches wird über die Schlaufe 3 geführt und danach als Einlage 4" in einer inneren Kammer der anderen Hälfte des Kammernschlauches zurückgeführt. Damit liegen die Einlagen 4' und 4" asymmetrisch bezüglich einer Mittellinie des Kammernschlauches. Alle weiteren Einlagen sind ebenfalls asymmetrisch bezüglich dieser Mittellinie angeordnet. Diese Anordnung wird als 'asymmetrische Einlagen' bezeichnet. Fig. 4A shows a sling sling with asymmetric inserts. The loosely inserted in the chamber tube 1 deposits 4 are indicated here by dashed lines. The insert 4 'in the outer chamber of one side of the chamber tube is passed over the loop 3 and thereafter returned as insert 4 "in an inner chamber of the other half of the chamber tube chamber hose. All other inserts are also arranged asymmetrically with respect to this centerline. This arrangement is referred to as 'asymmetric inserts'.

Wenn nun der Kammernschlauch sehr viele nebeneinanderliegende Kammern aufweist, kann er unter Zugspannung kaum mehr 'zusammenklappen', da aufgrund der asymmetrischen Anordnung eine Querkomponente der Zugspannung der Verformung entgegenwirkt.Now, if the chamber tube has many adjacent chambers, it can hardly 'fold' under tension, because due to the asymmetric arrangement, a transverse component of the tensile stress counteracts the deformation.

Fig. 5 zeigt einen Kammernschlauch mit einseitig angebrachter Beschichtung. Der Kammernschlauch 1 mit den Kammern 2, 2' und Einlagen 4 ist auf der einen Seite mit einer Beschichtung 7 versehen. Fig. 5 shows a chamber tube with one-sided coating. The chamber tube 1 with the chambers 2, 2 'and inserts 4 is provided on one side with a coating 7.

Der Kammernschlauch kann eine einseitige oder eine zweiseitige Beschichtung aufweisen. Er kann aber auch aus einem Material bestehen, das gewoben, gewirkt, extrudiert oder gegossen ist und auch als Rundum-Beschichtung hergestellt werden. Die Beschichtungen können gegossen, gespritzt, kalandriert, pulverbeschichtet oder gerakelt und als Lösung darauf ausgehärtet werden. Der Kammernschlauch kann eine Beschichtung aufweisen, die aus den gleichen Materialien oder aus unterschiedlichen Materialien wie der Kammernschlauch besteht.The chamber tube may have a one-sided or a two-sided coating. But it can also consist of a material that is woven, knitted, extruded or cast and also produced as an all-round coating. The Coatings can be cast, sprayed, calendered, powder coated or doctored and cured as a solution. The chamber tube can have a coating that consists of the same materials or of different materials as the chamber tube.

Fig. 6 zeigt einen Kammernschlauch mit einem umgebenden Schutzschlauch. Der Kammernschlauch 1 ist umgeben von einem Schutzschlauch 8. Es können auch mehrere Schutzschläuche übereinander vorliegen. Der Schutzschlauch kann aus synthetischem oder natürlichem Material, aus Gewebe, aus Gewirke oder als extrudiertes, gegossenes Element sein. Der Schutzschlauch ist über die ganze Länge des Kammernschlauches oder nur über einen Teil davon angeordnet oder kann aus mehreren Teilen gefertigt sein. Der Schutzschlauch dient gleichzeitig als Auflagefläche des Werkgutes und ist deshalb nach den Anwendungsbedürfnissen aus verschiedenen Materialien hergestellt. Er ist je nach Anwendung besonders hitzefest, flammwidrig, chemikalienbeständig, schnitt- und abriebfest. Er weist einen gewobenen oder gewirkten Mantel oder einen Doppelmantel auf, der besonders chemikalienbeständig ist und aus Polyamid (PA), Polypropylen (PP), Polyester (PES) oder Polyäthylen (PE), bzw. einem Mischgewebe dieser Materialien besteht. Er ist in der Regel aus hochschnittschutzfestem Schnittschutzmaterial gefertigt und weist durch spezielle Webarten eine enorm hohe Kantenfestigkeit auf, da die Kanten nicht unter der Zugspannung stehen. Besonders hitzefeste und flammwidrige Ausführungen sind aus Kevlar, Stahllitzen, Nomex oder aus einer Kombination davon. Durch verschiedene, spezielle Webarten wird eine enorm hohe Abriebfestigkeit, Schnittfestigkeit und Kantenfestigkeit erzielt. Fig. 6 shows a chamber tube with a surrounding protective tube. The chamber tube 1 is surrounded by a protective tube 8. There may also be several protective tubes one above the other. The protective tube can be made of synthetic or natural material, of woven fabric, of knitted fabric or as extruded, cast element. The protective tube is arranged over the entire length of the chamber tube or only over a part thereof or can be made of several parts. At the same time, the protective hose serves as a bearing surface for the work material and is therefore made of different materials according to the application requirements. Depending on the application, it is particularly heat-resistant, flame-retardant, chemical-resistant, cut-resistant and abrasion-resistant. It has a woven or knitted sheath or a double sheath, which is particularly resistant to chemicals and consists of polyamide (PA), polypropylene (PP), polyester (PES) or polyethylene (PE), or a blend of these materials. As a rule, it is made from cut-resistant cut resistant material and, thanks to its special weaves, has an extremely high edge strength, since the edges are not under tension. Particularly heat-resistant and flame-retardant designs are made of Kevlar, steel strands, Nomex or a combination thereof. Various, special weaves provide extremely high abrasion resistance, cut resistance and edge strength.

Der Kammernschlauch 1, die Einlagen 4, die Beschichtung 7, der Schutzschlauch 8 und der Kantenschutz können unterschiedliche oder aber dieselben Materialien aufweisen.The chamber tube 1, the inserts 4, the coating 7, the protective tube 8 and the edge protection may have different or the same materials.

Der Schutzschlauch wie auch der Kammernschlauch können aus extrudiertem oder gegossenen, synthetischem Material bestehen. In Frage kommen PVC, PU, Gummi oder synthetischer Gummi, eine Gummimischung, natürliches oder synthetisches Leder, gewobene oder gewirkte Stahllitzen, Garngewebe oder Gewirke, die einseitig, beidseitig oder rundum beschichtet sind.The protective hose as well as the chamber hose can be made of extruded or cast, synthetic material. In question are PVC, PU, rubber or synthetic rubber, a rubber compound, natural or synthetic leather, woven or knitted steel strands, yarn or knitted fabric, which are coated on one side, on both sides or all around.

Gemäss den gültigen CE-Normen kann der Kammernschlauch, der Schutzschlauch, die Schutzbeschichtung, die Einlagen und der Kantenschutz unterschiedliche Materialien aufweisen.According to the valid CE standards, the chamber hose, the protective hose, the protective coating, the inserts and the edge protection can have different materials.

Die CE-Norm EN 1492-1 definiert den Hebegurt mit Vorschriften, welche durch die Anordnung und Kombination der verschiedenen aufgeführten Materialien vollumfänglich eingehalten werden.The CE standard EN 1492-1 defines the sling with regulations that are fully complied with by the arrangement and combination of the various listed materials.

Fig. 7 zeigt eine Hebegurtschlinge mit zwei Schutzschläuchen. Der Kammernschlauch liegt hier von einem ersten Schutzschlauch 8 umgeben vor, sodass er von End 5 zu End 5' abgedeckt vorliegt. Über dem mittleren Teil des ersten Schutzschlauches 8 ist ein zweiter Schutzschlauch 8' angebracht, der in diesem Bereich einen zusätzlichen Schutz garantiert. So kann der Kammernschlauch mit mehreren verschiedenen oder gleichen Schutzschläuchen überzogen werden, die durch ihre Lage, bzw. Verteilung überdie ganze Länge des Kammernschlauches ein Verstärkungsprofil, ein Schutzprofil entstehen lassen, das den gewünschten Anforderungen jeweils gerecht wird. Fig. 7 shows a sling with two protective tubes. The chamber tube is here surrounded by a first protective tube 8, so that it is present from end 5 to end 5 'covered. Over the middle part of the first protective tube 8, a second protective tube 8 'is mounted, which guarantees additional protection in this area. Thus, the chamber tube can be coated with several different or the same protective tubes, which can arise through their position, or distribution over the entire length of the chamber tube a reinforcing profile, a protective profile that meets the desired requirements each.

Im Folgenden werden einige Ausführungsbeispiele erläutert.In the following, some embodiments will be explained.

Fig. 8 zeigt ein erstes Ausführungsbeispiel einer Hebegurtschlinge mit Schlaufen unterschiedlicher Länge. Die Schlaufen 3, 3' sind hier verschieden lang ausgebildet, um dem jeweiligen Anwendungszweck optimal zu dienen. So kann z.B. aus Platzgründen bei einer unterschiedlichen Zugänglichkeit der Last die eine Schlaufe der Hebegurtschlinge länger sein als die andere. Die Hebegurtschlinge weist einen Kammernschlauch 1 von 4 m und Schlaufen von unterschiedlicher Länge von 0,8 m und 1,8 m Länge auf, was eine Gesamtlänge von 6,6 m ergibt. Sie ist für eine Traglast von 100 t ausgelegt. Der Kammernschlauch ist in 14 Kammern 2, 2' aufgeteilt, in denen Einlagen 4 aus Polyestersträngen lose eingelegt sind und asymmetrisch vorliegen. Der Kammernschlauch besteht aus Polyestergewebe und ist mit einem Schutzschlauch 8 aus Polyestergewebe mit beschichtetem Polyurethan überzogen, der den gesamten Kammernschlauch abdeckt. Die beiden Schlaufen 3, 3' haben einen Schlaufenschutz 6, 6' aus Polyamidgewebe und sind breit/schmal gewoben, wobei der schmal-gewobene Teil in der Schlaufenkrümmung liegt. Fig. 8 shows a first embodiment of a sling sling with loops of different lengths. The loops 3, 3 'are of different lengths designed to serve the respective application purpose optimally. For example, for space reasons with a different accessibility of the load one loop of the sling sling be longer than the other. The sling sling has a chamber hose 1 of 4 m and loops of different length of 0.8 m and 1.8 m in length, giving a total length of 6.6 m. It is designed for a payload of 100 t. The chamber tube is divided into 14 chambers 2, 2 ', in which deposits 4 of polyester strands are loosely inserted and present asymmetrically. The chamber tube is made of polyester fabric and is covered with a protective tube 8 made of polyester fabric with coated polyurethane, which covers the entire chamber tube. The two loops 3, 3 'have a loop protection 6, 6' made of polyamide fabric and are wide / narrow woven, the narrow-woven part lies in the loop curvature.

Fig. 9 zeigt ein zweites Ausführungsbeispiel einer Hebegurtschlinge mit verstärktem Schlaufenschutz. Die Schlaufen 3, 3' sind neben dem Schlaufenschutz 6, 6' mit einer Verstärkung 9, 9' im Bereich der Krümmung versehen. Diese Verstärkung besteht aus breit/schmal-gewobenem Gewebe, aus extrudiertem oder gegossenem synthetischem Material. Die Schlaufen 3, 3' sind in der Regel mit einem breit/schmal-gewobenen Schlaufenschutz umgeben. Der Schlaufenschutz 6, 6' besteht aus einem synthetischen oder natürlichen Material, aus Leder, aus synthetischem Leder, aus Polyurethan, PVC oder Vliessstoff. Fig. 9 shows a second embodiment of a sling with reinforced loop protection. The loops 3, 3 'are provided in addition to the loop protection 6, 6' with a reinforcement 9, 9 'in the region of the curvature. This reinforcement consists of wide / narrow-woven fabric, extruded or cast synthetic material. The loops 3, 3 'are usually surrounded by a wide / narrow-woven loop protection. The loop protection 6, 6 'is made of a synthetic or natural material, made of leather, synthetic leather, polyurethane, PVC or Vliessstoff.

Fig. 10 zeigt ein drittes Ausführungsbeispiel einer Hebegurtschlinge mit breit/schmal gewobenem Kammernschlauch, Schutzschlauch und Schlaufenschutz. Der Kammernschlauch ist hier mit einem Schutzschlauch umgeben, der an den Enden 5, 5' wie auch der Kammernschlauch schmal-gewoben ist, während er in der Mitte 13 breit-gewoben vorliegt. Der Schlaufenschutz 6, 6' ist ebenfalls breit/schmal-gewoben, und zwar in der Mitte schmal, damit er eine kleine Fläche aufweist und in den Lasthaken passt. Dadurch kann die Hebegurtschlinge auf der Lastauflagefläche eine breite Abstützung der Last ergeben und im Schlaufenbereich eine platzsparende Aufhängung aufweisen. Fig. 10 shows a third embodiment of a sling sling with wide / narrow woven chamber tube, protective tube and loop protection. The chamber tube is here surrounded by a protective tube which is narrow-woven at the ends 5, 5 'as well as the chamber tube, while it is present in the middle 13 broad-woven. The loop protection 6, 6 'is also wide / narrow-woven, narrow in the middle so that it has a small area and fits into the load hook. As a result, the sling sling on the load bearing surface can provide a broad support of the load and have a space-saving suspension in the loop area.
