Heavy Duty Swivel Lifting Ring is a high-strength Rigging Hardware fitting specially designed for extreme heavy-load working conditions. Compatible with heavy-duty Chain Slings, large-tonnage wire rope slings, thickened lifting webbings and multi-branch heavy-load lifting systems, it is widely used for large-scale equipment hoisting, heavy mold shifting, large steel structure installation, engineering heavy-load transportation, mining machinery lifting and port heavy industry operations. Integrally drop-forged from ultra-high-strength alloy steel and treated with dual quenching and tempering heat treatment, the ring features an extremely compact and stable internal structure. It delivers ultra-high tensile strength, superior impact toughness and excellent fatigue resistance, capable of withstanding long-term ultra-high-frequency dynamic tension and complex angular impact, fully complying with industrial heavy-load lifting safety standards for various intensive continuous heavy-duty o…
