In lifting and rigging systems, G80 connecting links play a critical role in ensuring secure and flexible connections between chain slings and other rigging components. Although small in size, these fittings are essential for maintaining the overall safety, strength, and adaptability of Grade 80 chain assemblies.

This article provides a clear overview of the key features and typical applications of G80 connecting links.

What Is a G80 Connecting Link?

A G80 connecting link is a high-strength alloy steel fitting designed to connect Grade 80 chains with hooks, master links, or other lifting accessories. It allows chain slings to be assembled, adjusted, or repaired without welding, making it a practical and efficient solution in many lifting applications.

G80 connecting links are engineered to match the mechanical properties of Grade 80 chains, ensuring the integrity of the entire lifting system.

Key Features of G80 Connecting Links

High-Strength Alloy Steel

G80 connecting links are manufactured from quenched and tempered alloy steel, providing excellent tensile strength, wear resistance, and durability under heavy loads.

Secure Mechanical Connection

Most designs use pins or bolts to create a reliable mechanical connection. This ensures strong load transfer while allowing easy disassembly for inspection or replacement.

Compact and Practical Design

The compact structure makes G80 connecting links ideal for use in limited spaces, especially in multi-leg chain sling configurations.

Compatibility with G80 Systems

When correctly selected, G80 connecting links maintain the Working Load Limit (WLL) of the Grade 80 chain system and comply with relevant lifting standards.

Typical Applications:

Chain Sling Assembly

G80 connecting links are commonly used to connect chain legs to master links, hooks, or shortening devices during chain sling assembly.

Multi-Leg Chain Slings

In 2-leg, 3-leg, and 4-leg chain slings, connecting links allow flexible configuration and simplify replacement of individual chain legs.

Industrial and Construction Lifting

They are widely used in construction, manufacturing, steel structure handling, and general industrial lifting operations.

Maintenance and Repair

Because welding is not required, G80 connecting links are ideal for on-site sling maintenance, modification, and component replacement.

Selection and Safety Considerations

Always match the connecting link size with the chain diameter

Ensure the connecting link WLL is equal to or greater than the chain WLL

Inspect pins and bodies regularly for wear or deformation

Do not mix G80 connecting links with lower-grade chains

Proper selection and correct use are essential to safe lifting operations.

Conclusion

G80 connecting links are small but vital components in chain sling systems. Their strength, versatility, and ease of installation make them indispensable in modern lifting and rigging applications. By selecting high-quality G80 connecting links from a reliable manufacturer and using them correctly, operators can achieve safer, more efficient, and more dependable lifting performance.
