  • Patent number: 7637549
    Abstract: A lifting belt sling for lifting loads is comprised of a tubular structure having at least two chambers whereby forming, as one unit, a chamber tube that is contiguous over the width. Loosely inserted inserts are located inside the at least two chambers and endlessly extend from one end of the chamber tube to the other end thereof. The inserts overlap the ends of the chamber tube so that they form loops at this location, whereby the inserts, when situated in the loop area, are covered by a tube protective means. A protective tube, which surrounds the chamber tube and is formed by different weaves, significantly increases the resistance to abrasion, the resistance to cutting, and the edge strength. The lifting belt sling is designed for loads of up to 100 t.

  • Patent number: 7357433
    Abstract: A sling band for lifting loads is disclosed. The sling band has a first band, a second band and overlapping areas, whereby the ends of the bands lead into the overlapping areas. The first band includes first warp threads and the second band includes second warp threads, whereby the warp threads, together with weft threads, form a first and a second weave. In the overlapping areas, the warp threads are joined to one another where they form a web construction with the weft threads. The web construction includes at least one additional third weave that differs from the first and second weaves. A portion of the warp threads has a lower melting point than that of the remaining warp threads thus enabling the interwoven overlapping areas to be provided with increased strength using a weld.

  • Publication number: 20070137163
    Abstract: The invention relates to a rope-like structure (10), particular a core-spun rope, a cord and a rope, wherein the individual fibers, threads, strands and/or cords are provided in the form of longitudinal fibers of a longitudinal fiber structure (40) which are joined to another fiber (50) which extends in a substantially crosswise manner or at any particular angle in relation to the longitudinal fibers, such that the longitudinal fibers of the longitudinal fiber structure (40) are mutually non-slip and essentially cannot move backwards in relation to each other, wherein the other fibers (50) are untied, at least on one occasion, in relation to the longitudinal fibers and the latter are thus retained thereby.
