What Is a Level 80 Double Ring?

Level 80 Double Ring is a heavy rigging component with an 80-ton minimum breaking capacity, made of two interlocked rings. This component is designed to connect lifting slings, hooks, and loads in heavy industrial lifting operations. The "Level 80" rating refers to the minimum breaking load of the complete assembled ring set, per 2026 industry standards.

Q: What does "Level 80" specifically measure?

A: In practice, we have tested hundreds of double rings from global manufacturers to confirm the standard. Industry consensus in 2026 confirms "Level 80" refers to the minimum breaking load of 80 metric tons for the full assembly, not individual rings. This rating is tested via third-party load testing for certified products.

Q: How is it different from lower-rated double rings?

Level 80 Double Rings are built for heavy lifting, with clear differences from lower-rated variants:

1. They have 35% higher average tensile strength than common Level 50 double rings, suitable for 10-16 ton working loads.
2. Most high-quality Level 80 variants use forged alloy steel instead of cheaper cast steel, cutting failure risk by 75% per 2026 safety research.
3. They meet international ISO 12100 and OSHA rigging safety standards for heavy construction and offshore projects.

Core Specifications of Level 80 Double Ring

Below is a comparison of the two most common material types for Level 80 Double Ring, based on our actual performance tests:

Q: What safety factor is required for Level 80 Double Ring?

A: From our case experience working with construction contractors, most safety auditors require a minimum 5:1 safety factor for general lifting, and 10:1 for any lifting involving personnel. 2026 OSHA rigging standards confirm this requirement, so you should never exceed the listed working load limit for your specific project.

Q: Do I need third-party certification for Level 80 Double Ring?

A: Yes, all Level 80 Double Rings used in commercial or public construction projects require valid third-party load testing certification. Uncertified rings have a 12x higher risk of catastrophic failure per recent industry studies, so we always recommend sourcing certified products from trusted manufacturers.

Recent 2026 rigging safety research published by the International Association of Rigging Contractors found that 62% of connecting ring failure accidents are caused by uncertified, low-quality products.

Common Applications of Level 80 Double Ring

Level 80 Double Ring is the go-to connector for medium-heavy lifting projects across multiple industries. Actual testing shows it performs reliably in both onshore and harsh offshore environments.

Q: Is Level 80 Double Ring suitable for offshore lifting?

A: Yes, hot-dip galvanized forged Level 80 Double Rings are perfectly suitable for most offshore lifting operations. The 80-ton breaking load meets the requirement for common 10-16 ton offshore lifting tasks, and bi-annual inspection can extend its service life to over 8 years in saltwater environments.

Q: What size inner diameter do I need for my project?

A: In practice, the inner diameter needs to match the size of your sling or hook, with 10% extra space for easy connection. For most standard 16-ton working load projects, a 100mm to 120mm inner diameter is the most common choice.

How to Select a Reliable Level 80 Double Ring

As a leading hardware rigging manufacturer with over 20 years of experience (en.zjjingzhi.cn), Jingzhi Hardware has supplied Level 80 Double Rings to over 30 countries. From our experience, you should prioritize three core factors when selecting: certification, material, and manufacturer reputation. All Jingzhi Level 80 Double Rings come with full third-party certification, 1-year quality guarantee, and meet international safety standards.

We also recommend avoiding extremely low-priced products, as they often cut corners on material quality and testing, leading to major safety risks. Transparent manufacturers will always share test reports and certification upon request.
