Abstract

A lifting sling apparatus for lifting, holding, and transporting materials. More particularly, the invention relates to a lifting sling comprising a reinforced heavy-duty fabric body, such as, for example, a geotextile fabric, i.e., a synthetic fabric made from polypropylene, polyester, or other like synthetic materials, having heavy-duty sling webbing loops and reinforcement webbing on the body.

Claims15

Dependent claims

A lifting sling apparatus comprising:

a base layer comprising a fabric;
a first webbing strap having a first segment stitched along its length to the base layer and extending from a first side of the base layer to a second side of the base layer, the first webbing strap extending outwardly from the second side of the base layer and looping back to the base layer to form a first sling loop, the first webbing strap further having a second segment stitched along its length to the base layer and extending from the second side of the base layer to the first side of the base layer, the first webbing further extending outwardly from the first side of the base layer and looping back to the base layer to form a second sling loop,
wherein the first webbing strap is a first single and continuous loop of polymeric webbing;
a second webbing strap having a first segment stitched along its length to the base layer and extending from a third side of the base layer to a fourth side of the base layer, the second webbing strap extending outwardly from the fourth side of the base layer and looping back to the base layer to form a third sling loop, the second webbing strap further having a second segment stitched along its length to the base layer and extending from the fourth side of the base layer to the third side of the base layer, the second webbing strap further extending outwardly from the third side of the base layer and looping back to the base layer to form a fourth sling loop,
wherein the second webbing strap is a second single and continuous loop of polymeric webbing,
wherein the first segment of the first webbing strap overlaps and is stitched to the first and second segments of the second webbing strap forming first and second intersections, respectively, the second segment of the first webbing strap overlaps and is stitched to the first and second segments of the second webbing strap forming third and fourth intersections, respectively;
and
a first short loop extending from an edge of the base layer, the first short loop formed from a short webbing strap, the short webbing strap having a first segment stitched to and extending from the first intersection and stitched along its length to the base layer, a second segment extending from the first segment and forming the first short loop by extending out from the edge of the base layer and looping back to the edge of the base layer, and a third segment extending from the second segment and stitched along its length to the base layer.
