Abstract
The lifting sling of this invention comprises multiple discrete sling cores formed from a plurality of longitudinally extending parallel segments which are each contained inside separate cover material which form paths or channels arranged in an endless tubular loop. At least two separate sling cores are protected inside separate longitudinal endless paths of cover material which is sealed or fastened to prevent contact between the sling cores.
Claims9
A lifting sling which comprises at least two separate and distinct parallel endless load bearing cores, a seamless single tubular cover means which is bonded to form at least two channels in which said cores are located in an endless loop and separate from each other with said cover means also formed in an endless loop.
A method of constructing a lifting sling which comprises placing at least two separate and distinct cores of flexible load bearing material in parallel relationship laid end to end on a surface along a guide bar means mounted on said surface;
- sewing said cores at this distal ends to a holding means;
- pulling a seamless single tubular cover means having two ends over one end of said guide bar means to enclose said load bearing cores inside said cover means;
- sewing fastening means through said cover means longitudinally along an intermediate portion between the cores while keeping each core separate from the adjacent core so that the fastening means does not contact the core material;
- fastening the distal ends of each core together to form parallel endless loops of said cores;
- and fastening the distal ends of said cover means to form an endless loop.
