Product Advantage
Welded construction provides superior strength, ensuring reliability even in heavy-duty lifting situations. It is ideal for demanding applications such as construction and offshore operations.
Automated welding processes ensure uniformity and eliminate weak points found in cast or forged links, minimizing the risk of failure and ensuring long-lasting performance.
Fully compliant with ASME B30.9 and OSHA standards, the G80 Welded Master Link undergoes rigorous testing (proof load, MPI, UT) to guarantee safety and reliability in any heavy-lifting environment.
Available with protective coatings such as galvanized, painted, or stainless steel finishes, offering superior protection against corrosion, especially in harsh marine or industrial environments.
Ideal for a variety of industries, including construction, mining, shipbuilding, and emergency recovery, where heavy lifting and secure rigging are essential.

Product Applications
Used in high-rise building construction for lifting steel beams, precast concrete, and modular structures. Perfect for bridge and tunnel projects, as well as dam and power plant construction.
Crucial in shipbuilding, oil rig setups, and cargo handling at ports and docks, making it indispensable for lifting heavy components such as hull sections and turbines.
Supports heavy-duty equipment like draglines, excavators, and ore processing machinery, providing efficient rigging solutions for large-scale operations.
Handles large molds, presses, aircraft components, and machinery in automotive, aerospace, and steel mills, ensuring safe and effective heavy lifting.
Deployed for lifting wreckage, securing disaster recovery operations, and assisting military and defense in transport and field engineering.
Product Operate Guide
Before each lift, inspect the G80 Welded Master Link for:
Cracks, Bends, or Deformations: Discard if damaged.
Weld Integrity: Check for cracks or defects in welded areas.
Corrosion or Wear: Replace if rust or excessive wear is present.
Markings & WLL: Ensure the Working Load Limit (WLL) is legible and matches the rigging plan.
Correct Connection Method
Shackle Attachment: Use an appropriately sized bow shackle or anchor shackle. Ensure the pin is fully seated and secured (use a cotter pin or bolt lock).
Sling Attachment: Ensure that wire rope, chain slings, or synthetic slings fit freely inside the master link. Avoid sharp bends as sling angle affects load capacity.
Lift Slowly & Smoothly: Avoid sudden jerks or shock loads to protect both equipment and load.
Monitor Load Angle: Keep sling angles ≥60° to prevent overloading.
Never Exceed WLL: Account for dynamic forces (e.g., wind, movement).
Clean After Use: Remove dirt, grease, or chemicals that may lead to wear or corrosion.
Store in a Dry Place: Prevent rust (use anti-corrosion spray if needed).
Regular Inspections: Follow OSHA/ASME guidelines for periodic checks to ensure long-lasting performance.
FAQ
A: The G80 Welded Master Link is made from high-grade alloy steel, ensuring superior strength and resistance to wear, deformation, and fatigue.
A: Before each lift, inspect the master link for cracks, bends, deformations, weld integrity, corrosion, and markings. If damaged, discard and replace it.
A: This product is widely used in construction, marine, mining, industrial manufacturing, heavy machinery, and emergency recovery sectors.
A: Ensure correct connection with a bow or anchor shackle. Make sure the pin is fully seated and secured, and avoid sharp bends to maximize load capacity.
