All wire rope slings are not created equal.
What sling capacity does YOUR job require?
Mechanical Splice – IWRC (Internal Wire Rope Core)
Vertical, Choker or Vertical basket • Rated capacity in tons of 2,000 lbs.
Rated capacities shown apply only to 6×19 and 6×36 classification wire rope.
Note: Different capacities based on wire rope grade.
All Slings Manufactured by Certified Slings & Supply® are made with Flemish Eye Techniques & Mechanical Splice per ASME B30.9 and EIPS Grade Rope unless otherwise requested.
Mechanical Splice slings come in two basic types: the returned loop and the Flemish eye. In either case, the splice is completed by pressing (swaging) one or more metal sleeves over the rope juncture.
The returned loop is fabricated by forming a loop at the end of the rope, sliding one or more metal sleeves over the short end of the loop eye and pressing these sleeves to secure the end of the rope to the sling body. A drawback to this type of sling is that the lifting capacity of the sling depends completely upon the integrity of the pressed or swaged metal sleeve. Should the metal sleeve(s) fail or slide off, the entire eye will also fail.
The Flemish eye splice is fabricated by opening or unlaying the rope body into two parts, one having three strands and the other having the remaining three strands and the core. The rope is unlayed to allow the loop or eye to be formed by looping one part in one direction and the other part in the other direction and .laying the rope back together. The strands are rolled back around the rope body. A metal sleeve is then slipped over the ends of the splice and pressed (swaged) to secure the ends to the body of the sling. Nominal splice efficiencies are based on this splicing method. Splice efficiencies for other splicing methods should be confirmed.
