LGRIG® Double Swivel Shackle Grade 80

The Double Swivel Shackle Grade 80, also known as G80 Swivel Hoist Ring, Double swivel lifting point, Double Swivel Shackle Bolt.

Double Swivel Shackle delivers multi-directional load control through its patented dual-axis mechanism enabling simultaneous 360° rotation and 180° swivel articulation, engineered for precision positioning in complex lifting operations. Forged from high-grade alloy steel with drop-forged processing and corrosion-resistant powder coating, this certified lifting point accommodates 0.5–50 tonne capacities (e.g., 6.4-ton WLL models) while maintaining a 4:1 safety factor.

Featuring standardized metric/UNC thread compatibility and compact design for confined spaces, it excels in critical environments including marine construction (offshore platforms/docks), chemical processing plants, utilities infrastructure, and pulp mills where corrosion resistance and dynamic load management are paramount.
