Abstract
A lifting sling comprising a core of parallel yarns enclosed by a protective cover, the edges of which are interconnected by a lengthwise seam penetrating diametrically through the sling core so as to divide the latter into two portions, one on each side of the seam. In a direction perpendicular to a line interconnecting the centers of said portions, the cross-sections of said portions considerably exceed the cross-section of the sling in the area of the seam, whereby during use of the sling, the seam will be protected against wear and the stress taken by said two core portions.
Claims1
A lifting sling comprising a core consisting of first and second spaced longitudinally extending sections of substantially equal size interconnected by an intermediate longitudinally extending section of lesser dimension, said core being formed from a plurality of longitudinally extending parallel segments, a protective cover enclosing said core and defining an overlapping section, said overlapping section being juxtaposed to the interconnecting section intermediate section of lesser dimension of said core, and a seam extending through said interconnecting intermediate section of lesser dimension and diametrically through the overlapping portion of said cover for securing said cover and said core together, the transverse extent of said seam being substantially less than the corresponding dimension of said first and second core sections so that said seam will not engage a load when said sling bears thereagainst.
