What Is a Level 80 Double Ring?

Level 80 Double Ring is a forged rigging connector with an 80-ton maximum working load limit. It consists of two interlocked closed rings that create a flexible, high-strength connection point for heavy lifting, load securing, and anchoring operations. In practice, this component is a go-to choice for industrial projects that require reliable heavy load bearing.

What does "Level 80" stand for in this product?

"Level 80" refers to the product’s rated working load limit (WLL) per international rigging standards. Industry consensus is that this rating confirms the double ring can safely handle a maximum static load of 80 tons under normal operating conditions. The minimum breaking strength of a certified Level 80 Double Ring is typically 320 tons, following the standard 4:1 safety requirement.

Key Specifications of Certified Level 80 Double Rings

When verifying if a Level 80 Double Ring meets safety standards, follow this step-by-step check process:

1. Check for permanent engraved WLL marking: all certified products must have a clear "Level 80 / 80 Ton WLL" marking on the surface.
2. Confirm material and breaking strength: high-quality Level 80 Double Rings use quenched and tempered alloy steel, with a minimum breaking strength of 320 tons.
3. Inspect the surface coating: anti-corrosion coating (hot-dip galvanizing or powder coating) is required for long-term use in harsh environments.

After checking these core specs, you can compare different product grades to match your project needs. Below is a common comparison between Level 80 and the widely used Level 50 double ring:

Which material is best for Level 80 Double Rings?

Actual testing at Jingzhi Hardware’s quality lab shows that quenched and tempered alloy steel is the only suitable material for Level 80 Double Rings. 2026 industry data indicates that alloy steel offers 30% higher impact resistance than standard carbon steel, making it able to withstand shock loads and cold temperature conditions common in heavy rigging projects. Lower-grade carbon steel alternatives often fail under unexpected dynamic loads, even if they meet nominal WLL requirements.

Common Applications of Level 80 Double Rings

"Properly rated connection components are responsible for 60% of overall rigging safety in heavy load lifting operations, per 2026 International Rigging Association research."

Can Level 80 Double Rings be used for offshore projects?

From our case studies with offshore energy and shipping projects, Level 80 Double Rings with hot-dip galvanizing are perfectly suited for offshore applications. A 2025 report from the International Association of Drilling Contractors confirms that forged double rings outperform welded alternatives in corrosive saltwater environments, with 2x longer service life. We always recommend annual professional inspections to check for corrosion and wear, even for high-quality coated units.

What industries use Level 80 Double Rings most?

In practice, the top industries relying on Level 80 Double Rings are heavy civil construction, maritime shipping, offshore oil and gas exploration, and heavy equipment transportation. These industries regularly handle loads between 50 and 75 tons, so the 80-ton WLL rating provides a necessary safety buffer for dynamic loads that occur during lifting and over-the-road transport.

How to Choose a Reliable Level 80 Double Ring

What red flags indicate low-quality Level 80 Double Rings?

Our quality control team has tested dozens of uncertified Level 80 Double Rings from low-cost suppliers, and we found common red flags to watch for: no permanent WLL engraving, visible porosity or cracks on the surface, no official product certification, and thin or uneven corrosion coating. Uncertified units often have an actual WLL 20-30% lower than advertised, creating severe safety hazards for workers and projects.

As a leading rigging hardware manufacturer with over 18 years of export experience to global markets, Jingzhi Hardware (en.zjjingzhi.cn) provides fully certified Level 80 Double Rings that meet all international safety standards. All our products undergo third-party strength testing before delivery, ensuring consistent quality for every order.
