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.
