G80 Coupling Link: The Heavy-Duty Connector for High-Strength Chain Systems

The G80 Coupling Link is a precision-forged, high-strength component designed to securely join two ends of Grade 80 transport or lifting chains. As an essential part of certified rigging and load-securement assemblies, it ensures a reliable, seamless connection that maintains the integrity and rated capacity of the entire chain system.

Key Features:

• Grade 80 Alloy Steel: Heat-treated to meet ASTM A342 standards, with a minimum tensile strength of 800 N/mm² (116,000 psi) and a 4:1 safety factor—approved for overhead lifting.
• Robust Coupling Design: Engineered to connect two chain ends quickly and securely, often used to extend chain length or close chain loops.
• Forged & Proof-Tested: Manufactured under strict quality controls, with permanent markings for Working Load Limit (WLL), grade, and traceability.
• Smooth Contours: Minimize wear on chains and ensure safe handling during assembly and use.

Common Applications:

• Extending Grade 80 transport chains for securing heavy equipment on flatbed trailers
• Closing chain slings in multi-leg lifting configurations
• Repairing or modifying chain assemblies in industrial, construction, and oil & gas environments
• Recovery and towing operations requiring certified, high-strength connections

Safety & Compliance:

• Must be used only with Grade 80 chains and fittings to maintain system strength.
• Never exceed the marked WLL.
• Inspect regularly for cracks, deformation, or excessive wear—retire immediately if damaged.
• Complies with OSHA, ASME B30.9, and DOT regulations for lifting and transport hardware.

WORKING LOAD LIMIT IS BASED ON A DESIGN FACTOR OF 4:1
