Definitions
- the invention relates to a lifting sling according to patent claim 1 and uses thereof according to patent claims 6 to 8.
- Lifting straps are used in transportation and especially in the construction industry.
- Woven single or double-layer endless lifting straps are used in large quantities for lifting loads in accordance with the European standards EN 1492-1 (safety: requirements for flat woven lifting straps made of synthetic fibers) and EN 1492-2 (safety: requirements for round slings made of synthetic fibers).
- EN 1492-1 safety: requirements for flat woven lifting straps made of synthetic fibers
- EN 1492-2 safety: requirements for round slings made of synthetic fibers.
- 1 shows the view of a known, single-layer endless lifting belt in accordance with EN 1492-1. These textile tapes are sewn together so that they receive the appropriate delivery form for the user.
- Another object is to describe various uses of such lifting straps.
- this object is achieved with a lifting strap according to the wording according to claim 1 and with uses according to the wording according to claim 6 to 8.
- FIG. 1 perspective view of a known, single-layer endless lifting belt
- FIG. 2 perspective view of an endless lifting belt according to the invention
- FIG. 3 top view of an endless lifting belt according to the invention
- Fig. 4 first embodiment of an endless lifting belt
- Fig. 5 Second embodiment of a lifting strap as a lanyard
- Fig. 6 Third embodiment of a lifting strap with molded-over tensioning element as a lashing strap.
- Fig. 7 Fourth embodiment of a multiple arrangement of a lifting strap as a stop means or as a connecting means
- Fig. 1 shows the perspective view of a known, single-layer endless lifting belt.
- the two ends 1 and 1 'of a tape 10 are placed one above the other in an overlap area 2 and sewn, in a variety of ways can be done.
- a band 20 consists of two layers 3 and 3 ', which were woven as a two-layer band, the weaving points 4 and 4' being superimposed during the weaving.
- the belt 20 has a weaving point 5, from which the two warp sheets of the layers 3 and 3 'are combined, which results in an overlap area 7 of the warp sheets up to a further weaving point 6, in which the two warp sheets are interwoven with one another by means of a special weaving construction ,
- the first band 3 has first warp threads 8 and the second band 3 'has second warp threads 8', the warp threads 8, 8 'forming a first and a second weave with weft threads.
- the warp threads 8, 8 ' are brought together in the overlap regions 7, 7', where they form a weave construction with the weft threads which has at least one further third weave, which differs from the first and second weave.
- a two-layer tape is formed in the overlap area 7, which is characterized by particular strength.
- the weaving point 6 is also an interface at which the tape is cut.
- the band 20 has a weaving point 5 ', a weaving point 6' and an overlap area T with the difference that the weaving process, starting with the weaving point 6 ', initially creates a two-layer band in the overlapping area T, and then at the weaving point with divided warp webs to weave in two layers, creating layers 3 and 3 '.
- the endless lifting belt according to the invention is thus produced by simply cutting off or separating it from an endless woven material which alternately consists of a two-layer band 3, 3 'and single-layer overlap regions 7, T. Since the weave constructions used in the overlap regions 7, 7 'have sufficient strength in many cases, endless lifting straps can thus advantageously be produced by bypassing any sewing process. If a fiber with a lower melting point is selected for part of the warp threads 8, 8 'than is the case for the other warp threads, an increased strength can then be achieved in the interweaving overlap regions 7, T by welding.
- FIG. 3 shows a plan view of an endless lifting belt according to the invention. recognizable are the two-layer tape 3, the single-layer overlap areas 7, 7 'with the weaving points 5, 5' and the weaving points 6, 6 ', which at the same time also represent the interfaces of the endless lifting belt 20.
- Fig. 4 shows a first embodiment of an endless lifting belt with a breaking force of 800 kg.
- a 25 mm wide band made of high-strength polyester fibers was woven for two days to create a light width of 20 cm.
- the fiber strength was greater than 80 cN / Tex.
- the two layers were woven over a length of 2.5 cm.
- Fig. 5 shows a second embodiment of a lifting strap as a lanyard for a ski binding in plan view.
- a 12 mm wide band made of polyamide fibers was woven in two layers to create a light width of 22 cm. In the overlap areas, the two layers were woven over a length of 1.5 cm. After the tape had been cut off, it was turned and additionally sewn in the overlap areas. The result was a load capacity of more than 200 daN.
- FIG. 6 shows a third embodiment of a lifting strap with molded clamping element as a lashing strap.
- a lifting strap 10 which essentially corresponds to FIG. 4, is designed here for a load capacity of 300 kg. It is now inserted into an injection mold with which a clamping element 30 with a clamping bracket 31 made of plastic can be injected. The woven overlap areas are 3.5 cm long.
- Fig. 7 shows a fourth embodiment of a multiple arrangement of a lifting strap as a material loop in plan view.
- a 19 mm wide band made of polyamide fibers is woven in such a way that four openings 32, 32 ', 32 "of 8 cm are created, which are each delimited by overlapping areas 7, T. The latter are each 18 mm long.
- a lifting strap of this type is mainly used for technical climbing use, the material loop being used to hold carabiners 34 and similar equipment.
