4-LEG

Wire rope sling

consist of four independent wire rope legs connected to an alloy master link sub-assembly, engineered for maximum load distribution and stability when handling square, rectangular, or complex four-point lifting configurations in offshore, marine, and industrial applications.

Provides balanced weight distribution across four symmetrical pick points, drastically reducing load tilt and shifting during critical lifts.

Built with a main alloy master link and secondary sub-links to ensure proper leg orientation and prevent crowding on the crane hook.

Mechanically swaged Flemish eyes with steel sleeves deliver redundant mechanical safety and full rated capacity retention.

Fully tested, tagged, and rated for Working Load Limits (WLL) calculated at 60°, 45°, and 30° horizontal leg angles.
