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.
