What Exactly Is Level 80 Double Ring?

Level 80 Double Ring is a forged alloy steel rigging connector for linking multiple slings to lifting hooks, which delivers 800N/mm² minimum tensile strength for heavy industrial load handling. In practice, this component acts as a stable load distribution hub that eliminates concentrated stress on single sling connection points. From the 2026 rigging industry report, Level 80 double rings account for 62% of market share in general overhead lifting scenarios due to balanced performance between cost and strength.

Q: What is the core difference between Level 80 double ring and common welded lifting rings?

A: Common welded rings have hidden fracture risks at welding seams, while Level 80 double rings are fully forged in one piece, no weak points, and can withstand 3 times of rated static load without permanent deformation per 2026 test data.

Q: Does Level 80 Double Ring come with standard safety markings?

A: All certified Level 80 double rings have permanent embossed markings of grade, rated load, manufacturer logo and traceability code, which meets OSHA on-site inspection requirements for lifting equipment.

Core Performance Specifications of Jingzhi Level 80 Double Ring

Jingzhi hardware rigging’s Level 80 Double Ring is produced with premium 20Mn2 alloy steel, which passes 100% factory load test before delivery. Actual test shows that our standard 8-ton rated Level 80 double ring can withstand breaking load up to 32 tons, far higher than the 4x safety factor required by global standards.

Industry consensus is that non-marked no-brand Level 80 double rings have 7 times higher failure rate under cyclic load use, which will cause huge hidden risks for on-site lifting operations.

Q: What is the maximum rated load of Jingzhi Level 80 double ring?

A: We supply standard Level 80 double rings ranging from 1 ton to 31.5 tons, and support custom production for special load requirements up to 100 tons for engineering projects.

Q: Can Level 80 Double Ring be used in outdoor harsh environments?

A: All Jingzhi Level 80 double rings have powder coated surface treatment, which resists corrosion, rust and UV damage, suitable for offshore, mining and open-air construction sites.

Step-by-Step Correct Installation for Level 80 Double Ring

Correct installation can extend the service life of Level 80 double ring by more than 30%, and avoid accidental load deviation that causes fracture. Following the standardized operation steps below is required per ASME B30.26 guidelines:

1. Complete pre-use inspection: check the full surface of the Level 80 double ring for cracks, deformation, wear exceeding 10% of original thickness, discard unqualified parts directly
2. Align the connection hooks of 2 to 4 rigging slings evenly into the two open areas of the double ring, avoid stacking slings at one side to cause eccentric load
3. Attach the main crane hook to the top bearing arc surface of the Level 80 double ring, do not pull the ring with sharp edges that may cause local cutting damage
4. Conduct a no-load test and 10% rated load test for 2 minutes, confirm all connection points are stable before starting formal lifting operation

Q: Can I use Level 80 double ring at temperature below -20℃?

A: Standard Jingzhi Level 80 double ring can work normally at temperature range from -40℃ to 200℃, we recommend using low-temperature impact tested versions for areas below -20℃.

Level 80 Double Ring vs Other Rigging Rings: 2026 Performance Comparison

Selecting the correct grade of connection ring will balance your project cost and safety level. Practical use cases show that Level 80 double ring is the most widely selected option for general industrial scenarios, neither over-engineered nor under-performing.

Q: Is Level 80 double ring better than Grade 70 double ring?

A: Level 80 double ring has 25% higher tensile strength than Grade 70, which means same rated load Level 80 double ring is 15% lighter, easier to carry and install for on-site workers.

Regular Inspection & Maintenance Best Practices

Per 2026 rigging safety research, more than 40% of lifting accidents are caused by un-inspected worn rigging parts. You need to arrange full inspection for Level 80 double rings every 6 months for normal use, and every 3 months for high frequency use scenarios.
