Grade 80 / Grade 100 Single Master Links (5.3 Tonne to 63 Tonne)
Engineered as the primary load-bearing connection point for heavy-duty overhead lifting, these high-tensile single master links connect 1-leg and 2-leg sling assemblies directly to crane hooks, hoist lines, and master shackles. Rated for safe working loads from 5.3 tonnes up to 63 tonnes, their oversized oblong shape easily accommodates large crane hooks while maintaining balanced load alignment under tension.
Key Features:
 * High-Tensile Forged Alloy Steel: Drop-forged, quenched, and tempered to provide maximum structural toughness, high fatigue resistance, and shock load absorption.
 * Oversized Oblong Design: Wide inner dimensions allow smooth seating on standard crane hooks and gantry blocks without binding or crowding.
 * Proof Tested & Certified: Every unit is individually proof-tested to 2.5\times its Working Load Limit (WLL) in strict compliance with EN 1677-4 and ASME B30.26.
 * Smooth Seamless Weld: Precision flash-butt welded and ground flush to eliminate stress points and prevent snagging or wear on attached chain connectors, wire rope thimbles, or shackles.
 * High-Visibility Powder Coating: Finished with a durable, heat-cured safety finish (yellow or red) for long-lasting corrosion resistance and easy visual inspection on site.
Applications:
 * Top anchor point for 1-leg and 2-leg Grade 80 / Grade 100 chain slings
 * Steel wire rope and synthetic fiber web sling terminations
 * Heavy equipment rigging, structural steel erection, and shipyard crane operations
 * Offshore container lifting and heavy civil construction
