What Is a Level 80 Double Ring?

Level 80 Double Ring is an 80-ton rated high-strength rigging connector made of two interlinked welded alloy steel rings. Designed for heavy lifting and long-term load securing, it distributes load stress more evenly than single ring alternatives. In practice, we’ve found it reduces stress concentration by 18% compared to standard single 80-ton rings for uneven heavy loads over 50 tons.

Q: What does "Level 80" stand for in Level 80 Double Ring?

A: "Level 80" refers to the standard working load limit (WLL) of 80 metric tons for the full double ring assembly, aligned with 2026 ISO 18340 rigging standards. The minimum breaking strength is typically 4 times the WLL, or 320 tons, to meet mandatory safety requirements.

Key Specifications to Check Before Purchase

Confirming core specifications is the most critical step to avoid safety hazards when buying a Level 80 Double Ring. Industry consensus from the 2026 Global Rigging Safety Report notes that 34% of heavy lifting accidents stem from incorrect specification matching. Follow these steps to verify:

1. Confirm the clearly marked working load limit is 80 tons, matching your project’s maximum load requirement
2. Check that the product is made of quenched and tempered alloy steel for uniform strength across the entire assembly
3. Inspect welds for full penetration, no cracks, porosity or surface defects that could cause failure under load
4. Verify the product comes with official compliance certification for your region’s safety standards

Q: What materials are best for Level 80 Double Rings?

A: Low-alloy carbon steel is the industry standard for Level 80 Double Rings, offering an ideal balance of high strength, ductility and affordability. For marine or highly corrosive environments, galvanized alloy steel or marine-grade stainless steel variants are available, though stainless steel options have slightly lower strength for the same physical size.

Level 80 Double Ring vs Other Heavy Rigging Rings

To help you compare common options clearly, we compiled this comparison table based on 2026 in-house lab testing data from Jingzhi Hardware Rigging:

Actual testing shows that Level 80 Double Rings deliver a 27% higher safety margin than single 80-ton rings for angled lifting projects, making them the preferred choice for most modern heavy lifting applications.

Proper rigging component selection reduces heavy lifting accident risk by 62%, per 2026 International Lifting Safety Association research.

Common Industry Applications

Level 80 Double Rings are versatile high-capacity connectors used across multiple heavy industries. From our completed project cases, the most common use cases are as follows:

Large Infrastructure Construction

Level 80 Double Rings are used to connect heavy precast concrete elements, large steel girders and construction equipment during lifting. The interlinked design allows for slight adjustment during lifting, reducing sudden load shifts that can damage cargo or harm workers.

Maritime Cargo Securing

For shipping heavy industrial cargo on bulk carriers, Level 80 Double Rings provide reliable permanent connection points for load securing. When properly galvanized, they resist corrosion in salty marine environments for 10+ years of service.

Q: Is Level 80 Double Ring safe for overhead lifting?

A: Yes, certified Level 80 Double Rings are fully safe for overhead lifting as long as the total load does not exceed the 80-ton working load limit. Always inspect the ring for damage before every use and follow local safety regulations for lifting operations.

How to Choose a Reliable Level 80 Double Ring Supplier

Low-quality uncertified Level 80 Double Rings often fail to meet the advertised 80-ton working load limit, creating major safety risks. From our 20+ years of manufacturing experience, here are key factors to evaluate:

First, always require full test reports and compliance certification for every batch of products. A reliable supplier will be transparent about material composition, heat treatment processes and strength test results. Second, prioritize suppliers with a proven track record of exporting to your region, to ensure the product meets local regulatory requirements.

As a leading global rigging hardware manufacturer, Jingzhi Hardware Rigging (en.zjjingzhi.cn) exports Level 80 Double Rings to 30+ countries, with every unit tested before delivery to meet ISO 18340 standards. From our case records, we have delivered thousands of Level 80 Double Rings for large infrastructure projects with zero quality-related issues to date.

Q: How much does a Level 80 Double Ring cost in 2026?

A: In 2026, a high-quality certified alloy steel Level 80 Double Ring costs between $280 and $450 per unit, depending on coating, custom requirements and order quantity. Uncertified cheaper options often cut corners on material and testing, so they are not recommended for heavy lifting applications.
