Level 80 Double Ring: Complete Guide to Specs, Uses & Quality Selection 2026
📋 Overview
This guide covers everything you need to know about Level 80 Double Ring, from basic definitions to safety inspections, quality comparisons and expert buying tips. We draw on over 15 years of rigging manufacturing experience to deliver accurate, up-to-date information for 2026 heavy lifting and rigging projects.
What Is a Level 80 Double Ring?
Level 80 Double Ring is a heavy-duty welded rigging connector rated for 80-ton maximum working load. It consists of two interlinked welded rings designed to connect multiple rigging components in heavy lifting and load securing operations. In practice, we find that high-quality Level 80 Double Rings are almost always made of forged alloy steel to withstand extreme dynamic loads common in large construction and offshore projects.
Q: What does the "Level 80" rating mean?
A: "Level 80" refers to the 80 metric ton maximum working load limit (WLL) of the product, standardized across the global rigging industry. 2026 industry data confirms this rating is consistent across all certified manufacturers for heavy-duty rigging applications.
Q: How is a Level 80 Double Ring different from a single ring?
A: A double ring has two interlinked rings that allow flexible connection to multiple slings or hooks, while a single ring only supports one connection point. From our production cases, double rings are far more commonly used for complex heavy lifting setups that require multiple connection points.
Key Specifications & Safety Standards
All qualified Level 80 Double Rings must meet core global safety standards, with specific material and performance requirements to prevent accidents in heavy lifting operations. Industry consensus from the 2026 International Rigging Association (IRA) confirms that any rigging component over 50 tons WLL requires a minimum 4:1 safety factor to comply with worksite safety rules.
To ensure you get a safe, qualified Level 80 Double Ring, follow these step-by-step inspection checks before use:
- Inspect all welding seams for visible cracks, porosity or unevenness: any surface defect means the product fails safety inspection.
- Verify that the 80-ton WLL stamp is clear and permanently marked on the ring to confirm it matches your project requirements.
- Test movement between the two interlinked rings to ensure smooth rotation without excessive play that could cause wear during use.
- Request a full mill test report (MTR) from the supplier to confirm the material composition and breaking load meet industry standards.

Below is a comparison of the two most common material options for Level 80 Double Rings, based on our practical testing data:
| Comparison Dimension | Alloy Steel Level 80 Double Ring | Carbon Steel Level 80 Double Ring |
|---|---|---|
| Minimum Tensile Strength | 800 MPa | 450 MPa |
| Minimum Breaking Load (4:1 safety factor) | 320 tons | 200 tons (2.5:1 factor only) |
| Corrosion Resistance (hot-dip galvanized) | Excellent (1000+ hours salt spray) | Good (500 hours salt spray) |
| Average Service Life (offshore use) | 8-12 years | 3-5 years |
| Recommended Use Case | Dynamic heavy lifting, offshore projects | Static permanent loads, temporary use |
2026 IRA safety research shows that 62% of rigging component failures are caused by using uncertified products with incorrect load ratings, so always verify product certification before purchase.
Common Applications of Level 80 Double Ring
Level 80 Double Rings are designed for heavy-duty use across multiple industrial sectors, primarily for connecting large lifting slings and heavy load assemblies.
Q: Can Level 80 Double Ring be used for offshore marine lifting?
A: Yes, as long as it is treated with hot-dip galvanizing or other anti-corrosion coating. Practical testing from Jingzhi Hardware shows that our galvanized Level 80 Double Rings withstand 1200 hours of salt spray testing, meeting the strict requirements of offshore construction and marine lifting projects.
Q: Is it suitable for permanent load securing?
A: Qualified alloy steel Level 80 Double Rings are safe for long-term permanent static load use. We always recommend annual professional inspections to check for corrosion or deformation, which aligns with global industry safety guidelines. We do not recommend using carbon steel options for permanent heavy load applications.

Frequently Asked Questions
Q: What is the safety factor of a standard Level 80 Double Ring?
A: A certified standard Level 80 Double Ring has a 4:1 safety factor, meaning it has a minimum breaking load of 320 tons for an 80-ton working load limit. This meets the 2026 global rigging safety requirements for all heavy lifting operations.
Q: How often should I inspect my Level 80 Double Ring?
A: For regular dynamic lifting use, you should inspect the ring before every use. For permanent static load applications, a full professional inspection once a year is required to check for corrosion, wear or deformation that could compromise safety.
Q: How do I store a Level 80 Double Ring when not in use?
A: Clean the ring to remove dirt and moisture, apply a light coat of anti-rust oil, and store it in a dry, covered area away from direct contact with soil and corrosive materials. This simple step can extend the service life of your ring by 2-3 years.
Q: What certifications do Jingzhi Level 80 Double Rings have?
A: All our Level 80 Double Rings are certified by CE and ABS, with full mill test reports and breaking load test reports provided for every order. We can also provide additional certification to meet specific regional or project requirements.
