The Crosby Heavy Lift Swivel Hoist Ring HR1000 with UNC thread (WLL 3,175 kg) is engineered for the most demanding lifting applications, offering exceptional strength, durability, and ease of use. Constructed from forged alloy steel, this swivel hoist ring is designed to withstand tough field conditions while providing reliable performance over time. Its optimised design includes a larger bail opening than standard hoist rings, allowing for versatile rigging and improved handling of heavy loads.

This model features a 3/4‑10 × 3.00‑inch UNC bolt, providing a secure and robust mounting point, with all torque specifications clearly stamped on the washer for safe and accurate installation. The top washer is colour-coded red to indicate the UNC thread type, while raised lettering displays the Crosby name or “CG” and the product identification code (PIC), ensuring full traceability. The working load limit (WLL) and recommended torque are permanently marked on each washer, making inspection and verification quick and reliable.

Each Crosby Heavy Lift Swivel Hoist Ring is individually proof-tested to 2.5 times the WLL, providing verified strength and unmatched reliability. The Crosby Heavy Lift Swivel Hoist Ring is available in both UNC and Metric thread styles, and the alloy socket head cap screws meet ASTM A574 standards. Bolt sizes are clearly marked for easy reference, further simplifying installation and maintenance.
