G80/100 Strong Ring High Strength Welding Connecting Ring

1. Superior Strength and Load-Bearing Capacity

• Crafted from high-strength alloy steels such as 20CrMnTi, 35CrMo, or 40Cr, and manufactured through precision forging processes, these rings achieve industry-leading strength grades (e.g., G80, G100). This ensures they can withstand extreme tensile forces, with breaking loads ranging from hundreds to thousands of kilonewtons (e.g., 616KN for 2286 规格 and 3600KN for 52170 规格), meeting the demands of heavy-duty lifting in sectors like construction, metallurgy, and port operations.

2. Exceptional Toughness and Impact Resistance

• Through rigorous heat treatment (e.g., quenching and tempering), the material gains excellent toughness, enabling the ring to absorb impact loads without brittle fracture. This critical feature enhances safety in dynamic lifting scenarios, where sudden stress or vibration is common.

3. High Reliability and Longevity

• Every unit undergoes strict quality testing, including tensile testing, fatigue testing (with fatigue life exceeding 70,000–100,000 cycles for most models), and dimensional inspections. Compliance with international standards such as EN 1677-4 and ASTM A952/A952M guarantees consistent performance, reducing the risk of failure during long-term use.

4. Corrosion Resistance for Versatile Environments

• Many models feature anti-corrosion treatments like galvanization or powder coating, making them suitable for harsh environments such as humid ports, chemical plants, or outdoor construction sites. This extends their service life and reduces maintenance costs.

5. Easy Integration and Operational Efficiency

• Designed with an ergonomic elliptical or custom shape, the rings seamlessly connect with chains, wire ropes, hooks, and shackles. Their simple yet robust structure allows quick and secure assembly, minimizing downtime and improving workflow efficiency in lifting operations.

• Construction and Infrastructure:

  In construction sites, they are used to lift steel beams, concrete blocks and other heavy - duty materials1. In bridge and tunnel projects, they can enhance the stability of structures during natural disasters such as earthquakes2.

• Industrial Manufacturing:

  In steel mills, they are used to transport molten steel ladles and steel ingots. In the production lines of other manufacturing industries, they help move and maintain large equipment and components.

• Logistics and Transportation:

  They are essential tools in ports, warehouses and distribution centers, helping to safely handle heavy goods. They are also used in vehicle recovery to tow or lift disabled vehicles.

• Marine and Offshore Engineering:

  In shipbuilding, repair and maintenance, they are used to move heavy - duty equipment and components. In offshore oil and gas projects, they are used for lifting offshore platform equipment and have corrosion - resistant properties.

• Power and Energy:

  They are used for lifting utility poles and transformers in power grid construction, and for installing and maintaining wind turbine components in wind power generation.

• Entertainment and Events:

  They are applied in stage rigging to suspend lighting, sound equipment and stage props, ensuring safety.

1、Pre use inspection: 

Confirm that there are no cracks, deformations, or severe corrosion on the surface, that the specifications match the connected components, and that the strength markings are clear and complete.

2、Correct installation and connection:

 Ensure alignment with the load direction and avoid lateral force; When connecting components such as chains and hooks, they must be fully clamped to prevent loosening.

3、Load operation specifications: 

Overloading is strictly prohibited. When lifting, apply force steadily to avoid impact; Maintain balance during the load process and prohibit personnel from staying below or nearby.

4、Post use maintenance:

 Clean stains in a timely manner and store them dry to avoid moisture or heavy objects squeezing them; Regularly conduct professional inspections and replace damaged parts immediately.

5、Prohibited behaviors: 

Welding, heating and modification are not allowed, damaged parts cannot be used for operation, and lateral dragging of loads should be avoided.
