Definitions

  • the invention relates to a lifting belt for lifting and transporting loads, about boxes, pipes or the like.
  • Bands are often coated with plastic used to protect the tape from cuts, wear, moisture or To protect pollution.
  • Both the uncoated and the coated Lifting straps have the disadvantage that they have low inherent rigidity and are therefore difficult to handle in some situations. For example lifting straps often have to be pushed under loads, which difficulties due to their low inherent rigidity
  • GB-A-1561193 is a double or hollow product Strap for hoists known, in the connection-free spaces a loose insert made of wires, bundles of fibers, strands or ropes is arranged, which serves to reinforce the strap.
  • the object of the invention is to propose a lifting strap that is easier to handle is.
  • the lifting strap then comprises a two-layer strap part, which, depending on the type the load to be lifted is designed to be more or less long. Between those an intermediate layer is formed from two layers of the fabric belts forming the belt part arranged flexible plastic material.
  • This three-layer structure gives the lifting strap so much inherent rigidity that it can easily be pushed through a load and can be gripped from the other side of the load.
  • the fabric tape is so flexible that it is wrapped around a load and with its ends, which are preferably designed as loops, in a crane hook can be hung. Because of their bending stiffness and kink stability the lifting straps can also be easily pushed through openings.
  • the three-layer structure also ensures that the lifting straps are relatively wide can cantilever without kinking.
  • the band part goes in on both sides of the Loops formed over loops.
  • the strap part or the entire lifting strap is ring-shaped.
  • the fabric belts are approximately in the form of two concentric, radially spaced from the intermediate layer Rings arranged.
  • the intermediate layer is preferably made by pouring a flowable Plastic material between the fabric belts spaced apart in a mold receive.
  • Polyurethane is preferably used as the plastic material. This material can be practically in the form of two flowable components Pour room temperature between the fabric belts. The liquid material can easily penetrate into the near-surface layers of the fabric straps. After this Hardening of the polyurethane becomes a firm bond between the intermediate layer and get the fabric straps.
  • a lifting strap according to the invention has a band part 1, which is formed by two fabric belts 2, 3.
  • the band part is ever of different lengths as required and goes in loops on both sides 4 about.
  • the length of the intermediate layer 5 corresponds to the length of the Band member.
  • the loops 4 are formed in that one of the two fabric belts, for example, the fabric belt 3 is extended, with its end 6 on the fabric belt 2 rests and is sewn to it.
  • an endless, closed ring Fabric belt is used for the production of the fabric tape of FIG.
  • Fig. 2 shows a lifting strap
  • the strap part 1a has no loops, but that is closed in a ring. It is composed of an outer fabric belt 7 and an inner fabric belt 8. Both belts are spaced radially arranged to each other and with each other via a polyurethane intermediate layer 5a connected.
  • An annular lifting strap can e.g. used in tube loading become. With this type of loading, a bundle of tubes is made up of two ring-shaped ones Includes lifting straps. The rings are placed in a crane hook by a stopper hooked. The stop must be on the top of the tube bundle stand, which carries a high risk of accidents. This dangerous activity is not necessary with a lifting strap ring with an elastic intermediate layer.
  • the lifting straps Due to the three-layer structure, the lifting straps get one Inherent rigidity, that they protrude in an arc shape over the bundle to be raised so that a crane operator can lift the crane hook without the help of a stopper can be hooked into the lifting sling and later released again. If several bundles lie on top of each other, the lifting strap rings fit the bundle shape therefore do not take up any space and do not cause any damage on the pipes.
