Definitions

  • the invention first relates to a load lifting sling with the features listed in the preamble of claim 1, known from GB-A-1 556 818.
  • Such lifting slings also known as “cloverleaf” slings, traditionally consist of a textile band fabric.
  • lifting slings cannot be produced with any load-bearing capacity, because the thickness of the plastic layer producing the cross-connection between the textile threads is limited by the need to ensure a minimum degree of flexibility of the lifting sling.
  • Another disadvantage of these lifting slings is that the user can only obtain them in circumferential lengths specified by the manufacturer.
  • the invention has for its object to provide a lifting sling of the type mentioned in such a way that the possibilities of easy manufacture of lashing loops can only be maintained by partially cutting the cross-connection existing between the supporting textile threads, but otherwise the disadvantageous cross-connection between the supporting textile threads is avoided by a plastic layer.
  • This object is achieved by the features listed in the characterizing part of claim 1.
  • the invention makes use of the fabric construction known per se from FR-A-1 396 435 and FR-A-1 258 862 for the application of the hot-cutting process taking place in the warp thread longitudinal direction.
  • the band 1 to 4 are essentially produced in that the band 1 is cut off from a band supply of practically infinite length in the respective desired circumferential length of the lifting loop and the band section with its two ends is initially closed by a seam 2 Loop is connected.
  • the loop is then designed like a cloverleaf (Fig. 1-3) or in the form of an elongated oval (Fig. 4) before the lashing loops 4 are attached in the area of the lifting loops 3 and the load floor 5 is attached if necessary.
  • the lashing loops 4 - in the case of FIGS. 2 and 3 crosswise - are tied together by a traction means 7 on the top of the load stack 6.
  • the load stack 6 is held together even in the lowered state (FIG. 3, 4), without the free accessibility of the lifting loops 3 for hanging the crane hooks 8 being hindered thereby.
  • the band 1 is a band fabric with warp threads 10, 17 extending in the longitudinal direction 9 of the belt and weft threads 11 running in the transverse direction of the band. It extends in the longitudinal direction 9 of the strip over the entire strip length.
  • the warp threads 17 of the band fabric formed by textile threads made of a plastic, the melting temperature of which is lower than the melting temperature of those warp threads 10 which form the lateral band width regions assigned to the spacings 13, 14.
  • These textile threads formed from comparatively low-temperature melting plastic are also simply referred to below as "melt threads".
  • the band width range assigned to the larger distance 14 is the load bearing area of the lifting sling made from the band, while the band width range assigned to the smaller distance 13 forms the lashing loops 4.
  • This bandwidth range assigned to the shorter distance 13 therefore only has to absorb lower tensile forces than the load range of the later lifting strap. Therefore, the weave density of this area can also be lower than that of the support area (distance 14).
  • the warp threads 10 consist of a plastic, the melting temperature of which, however, is significantly higher than the melting temperature of the melt warp threads 17 in the cutting width range 12.
  • a longitudinal cut is made only in the longitudinal direction 9 of the belt or in the warp thread direction into the cutting width region 12 of the melt warp threads 17 under the effect of heat, which only melts the melt warp threads 17, but not that in the two lateral band width regions 18,19 lying warp threads 10 causes.
  • At least one textile thread made of a plastic is also added to the weft threads 11 of the band fabric, the melting temperature of which is lower than that of the other weft threads, whereby the same effect is achieved during hot cutting: the comparatively low-temperature melting weft thread (melting thread) is also melted during hot cutting and facilitates the desired production of a material connection, while the comparatively higher temperature melting textile threads (warp threads 10 and weft threads 11) do not change their state of matter under the influence of temperature and remain undamaged.
  • a mechanical hot cut in the longitudinal direction 9 and thereby cutting through the weft threads 11 such a cut can also be carried out by means of radiation, ultrasound or a blower.
  • the lashing loops can also be produced mechanically or automatically by introducing the slits 20 after the loop configuration has been laid out.
  • the cutting width region 12 is delimited on both sides by at least one warp thread 21 which is different in color from the band fabric, in order to prevent damage to the load-bearing band width region 19 in particular in the case of manual insertion of the slots 20 and to ensure that the hot cut is introduced into the desired region.
