Claims18
A synthetic sling comprising:
- a cover having fibers twisted in only a first direction;
- and
- a load-bearing core within the cover, wherein the load-bearing core is made from a plurality of core strands having a helical twist, wherein the core strands are twisted in a second direction, the first direction of the cover having an opposite lay from the second direction of the core strands.
A non-metal sling comprising:
- a load-bearing core, wherein the load-bearing core is made from a plurality of core yarns having a helical twist wherein each core yarn is made from a plurality of threads wherein the threads are twisted in a second direction;
- and
- a cover that encapsulates the load-bearing core, the cover having twisted fibers twisted in only a first direction, the first direction of the cover having an opposite lay from the second direction of the threads.
