Definitions

  • the invention relates to a round sling for use on suspension means with a first protective tube partially surrounding the round sling to form a strop.
  • Round slings and a strop formed from them have long been known, for example from EP 32749 Al. All individual elements of the round sling, which form the sling, are known to be irreversibly connected to each other, so sewn. Furthermore, it has been shown in practical use that increased wear occurs on loops of the round sling in the area where a suspension element, for example a crane hook, is in contact when used in a functional manner. The same applies to a load handling area, for example when transporting a steel coil using a round sling.
  • the object of the invention is to further improve a round sling in the form of a sling.
  • a round sling according to the invention for use on suspension means has the following features.
  • the round sling has a first protective tube partially surrounding it to form a sling, end regions of the round sling not being enclosed by the first protective tube and the end regions therefore forming loops.
  • At least one perimeter strap as loop reinforcement is arranged, which rests on an outer surface of the respective loop of the round sling and is thus placed around the loop.
  • the at least one wrapping band is preferably not separately connected to the loop by sewing, gluing or the like.
  • connection of the at least one surrounding tape to the first protective tube is, however, done by sewing, for example. All other suitable connection forms are also within the scope of the invention, so all non-positive and / or positive or material connection types.
  • an openable second protective tube is arranged on the respective loops, which encloses the surrounding band and thus, as it were, an area of the round sling on which a tag means can be arranged and which completely or at least partially conceals the loop and the surrounding band, that is to say axially in the longitudinal direction. In any case, such a concealment is necessary, so that the respective protective tape is reliably locked by the second protective tube.
  • the second protective hose ensures that the strap is fixed as a loop reinforcement.
  • a closure area of the respective second protective hose is advantageously located outside a contact surface with the suspension element in order to reduce impairment of the connection area and thus impairment of the locking of the respective second protection hose due to mechanical stress by the suspension element.
  • the load capacity of the round sling is further improved by the arrangement according to the invention and the interaction of the individual components described above.
  • the power dissipation within the round sling is improved.
  • the multilayer structure also improves the durability of the round sling.
  • An interchangeability of individual elements of the round sling in the form of the sling is also ensured.
  • an openable third protective tube is arranged above the first protective tube and essentially encloses the first protective tube. This results in improved protection of the round sling in the load handling area if, for example, the round sling is used to transport coils, according to steel coils.
  • a Velcro fastener for example, is provided as a connecting means for the openable second and third protective tubes.
  • the first protective tube can preferably be reversibly connected to the round sling by being loosely pushed onto the round sling or, which is not preferably the case, can be irreversibly connected to the round sling by being on the round sling as part of the formation of the Stropps is pushed on loosely and then an area of the first protective hose between the two strands of the round sling is at least partially connected, so it is sewn.
  • the first protective tube then has two chambers. Nevertheless, as a rule it is arranged displaceably on the round sling, and preferably all connections are provided reversibly because of the ease of exchangeability.
  • An improved locking of the first or of the first and of the third protective tube can furthermore take place by means of at least one closure, the at least one closure being arranged at the respective ends of the first protective tube or at the respective ends of the first and third protective tube and preferably, but does not necessarily lead through the interior of the loop when it is closed.
  • the at least one closure can be firmly connected to the first and / or the third protective tube or can be a separate element which can penetrate or pinch the first protective tube and / or the third protective tube for the purpose of locking.
  • the at least one closure is advantageously reversibly closable, for example by means of a clamping device. Clamp locks, buckles or similar devices come into consideration.
  • the at least one closure is a band section.
  • FIG. 1 is a schematic representation of a round sling according to the invention
  • Fig. 2 is a schematic representation of part of a round sling with end area.
  • a round sling 1 according to the invention for use on suspension means has a first protective tube 2 which partially surrounds it to form a sling, end regions of the round sling 1 not being enclosed by the first protective tube 2 and the end regions therefore forming loops 4, 4 '.
  • a surrounding band 5, 5 ' is arranged as a loop reinforcement.
  • the respective surrounding band 5, 5 ' lies loosely on an outer surface 6 of the respective loop 4, 4' of the round sling 1 and is thus placed around the loop without further attachment.
  • the respective surrounding band 5, 5 ' is sewn twice with the first protective tube 2 at the ends 3, 3' according to FIGS. 1 and 2, so that the respective surrounding band 5, 5 'also forms a loop.
  • an openable second protective tube 7, 7 ' is arranged on the respective loops 4, 4', which encloses a region of the round sling 1, on which a suspension element can be arranged and, as it were, almost completely conceals the respective encircling band 5, 5 ', and so to speak locked.
  • a closure area of the respective second protective hose 7, 7 ' is located outside of a contact area with the suspension element when it is functionally connected to the round sling 1. This means that the locking area is not exposed to any direct stress from the suspension element.
  • An openable third protective tube 8 is arranged above the first protective tube 2, which essentially surrounds the first protective tube 2, that is to say it conceals it in its longitudinal direction.
  • a Velcro fastener is provided as a connecting means for the openable second and third protective sleeves 7, 7 'and 8.
  • the closure 9 is arranged at the respective ends 3, 3 'of the first protective tube 2 and the third protective tube 8.
  • the closure 9 leads through the loop interior 10 when it is closed in terms of its function. A pulling off from the round sling 1 is thus excluded.
  • the closure 9 is formed by two detachable straps each arranged at the ends 3, 3 ', each with a belt clamp, the closure 9 penetrating the first protective tube 2 and the third protective tube 8 at slots provided for this purpose. LIST OF REFERENCE NUMBERS
