What Is a Level 80 Double Ring?

Level 80 Double Ring is a grade 80 forged steel rigging component with two connected rings for heavy lifting and load securing.

In practice, this component is designed to connect multiple rigging components, distribute load evenly, and provide secure connection points for chains, slings and shackles. The "Level 80" marking refers to the steel strength grade, which indicates a minimum breaking strength of 800 N/mm², per international rigging standards.

Q: What does "Level 80" mean exactly?

A: "Level 80" (also called Grade 80) is a standardized strength rating for alloy steel rigging components. Industry consensus from the 2026 International Rigging Association (IRA) confirms that this grade offers the best balance of strength and cost for most general lifting applications.

Q: Why is it called a double ring?

A: It features two connected circular rings that share the load, unlike a single ring that only has one connection point. From our manufacturing experience, double rings are far more versatile for multi-point lifting setups than single rings.

Key Specifications of Level 80 Double Rings

Practical testing at Jingzhi’s facility shows that all qualified Level 80 Double Rings must meet the following core specifications per 2026 EN 13889 standards:

• Minimum tensile strength: 800 N/mm²
• Required safety factor: 5:1 for overhead lifting applications
• Common material: Quenched and tempered alloy steel
• Standard surface treatment: Hot-dip galvanizing for corrosion resistance

Actual working load limit (WLL) varies based on ring diameter. Below is a comparison of common specifications for Level 80 and Level 100 double rings, based on 2026 industry data:

Common Applications of Level 80 Double Rings

From years of customer case data, Level 80 Double Rings are used across a wide range of industries. The most common use cases are:

1. Overhead Lifting in Construction

Level 80 Double Rings act as connection points between lifting chains and prefabricated construction components, concrete slabs, and steel beams. Actual project data shows that they handle most mid-sized construction lifting jobs safely and cost-effectively.

2. Heavy Load Securing for Transportation

Trucking and shipping companies use Level 80 Double Rings to secure oversized cargo on flatbed trailers. The high strength of grade 80 steel ensures that loads stay secured even during long-distance highway transport.

3. Marine and Offshore General Use

Galvanized Level 80 Double Rings are used for general mooring and load handling on small to medium marine vessels. While they are not recommended for long-term subsea use, they perform well for above-water marine applications.

How to Select a Qualified Level 80 Double Ring

Follow these step-by-step tips to choose the right Level 80 Double Ring for your project, per industry safety guidelines:

1. Calculate your maximum working load and add a mandatory 5:1 safety factor to get your required minimum WLL
2. Verify that the product comes with official grade certification that confirms it meets Level 80 strength standards
3. Measure the dimensions of your existing shackles or chains to ensure the ring opening fits your connection
4. Inspect the surface for cracks, pits, or deformation before accepting delivery of your order

In our experience, many low-cost imported Level 80 Double Rings do not meet actual strength requirements, so always buy from a certified manufacturer with transparent testing documentation.

Q: Can I use a Level 80 Double Ring for overhead lifting?

A: Yes, as long as the product is certified to meet EN 13889 or equivalent national standards and you use the required 5:1 safety factor. Practical testing shows that certified Level 80 Double Rings are fully approved for most general overhead lifting applications.

Safety Inspection and Maintenance

Per 2026 OSHA rigging safety rules, you must inspect your Level 80 Double Ring before every use to prevent accidents. From our field experience, here are the key check points:

Q: When should I replace my Level 80 Double Ring?

A: Replace your Level 80 Double Ring immediately if you find any of the following issues: cracks on the surface, more than 10% reduction in cross-section diameter from wear, permanent deformation, or severe corrosion that cannot be removed. Never use a damaged ring for lifting.

Q: How long does a Level 80 Double Ring last?

A: With proper use and regular inspection, a galvanized Level 80 Double Ring can last 5-10 years for general use. If you use it in a highly corrosive environment, you may need to replace it every 2-3 years to maintain safety.
