Wire Rope Slings
Single part body mechanically spliced wire rope slings.
Eyes are typically formed using a flemish eye splice. The ends are secured by pressing a metal sleeve over the ends of the strands of the splice. Pull follows a direct line along the center of the rope and eye. Single part body mechanical splice slings have a higher rated capacity than hand-spliced slings.
Flemish Eye Splice
In the standard flemish eye mechanical splice, wire rope is separated into two parts: three adjacent strands to one part and three adjacent strands along with the core to the other part. The two parts are then re-laid back in opposite directions to form an eye and ends are secured with a pressed metal sleeve.
Swaging provides a good grip
This photo shows a cutaway of a metal sleeve that’s been swaged onto a splice. Notice how metal flows into the valleys between strands to positively prevent ends from unlaying when the sling is used within its rated capacity.
