Grade 80 & Grade 100 Alloy Steel Master Link Assemblies
Product Description
Yile Machinery is a premier supplier of high-strength, forged alloy steel master links and master link assemblies. As the primary connection point for any multi-leg sling, the master link is a critical component where safety and strength are non-negotiable. Our master links are engineered and certified for the rigors of overhead lifting in construction, manufacturing, and marine environments.
The Core of Your Lifting Sling: Uncompromising Strength
The master link assembly is the top-level component that connects your chain, wire rope, or synthetic sling to the crane or hoist hook. A high-quality assembly is essential for safe and balanced lifts.
Engineered for Safety: Our links are manufactured from quenched and tempered alloy steel, providing maximum strength and durability.
Certified Performance: Each link is proof-tested to 2.5 times the Working Load Limit (WLL) and certified to meet or exceed industry standards like ASME B30.9 & EN 1677.
Versatile Design: The large, oblong shape is designed to fit a wide range of crane hooks, while the included sub-links allow for the easy connection of single or multi-leg slings.
Key Features & Engineering Excellence
Forged Alloy Steel Construction: Forged, not cast, for superior grain structure and resistance to shock loads and fatigue.
Grade 80 & Grade 100 Options: We offer both G80 (standard heavy lifting) and G100 (providing ~25% higher lifting capacity for the same size) options.
Durable Powder-Coated Finish: Provides excellent corrosion resistance and high visibility for safety inspections.
Clearly Marked: Each link is permanently embossed with the manufacturer's mark, size, grade, and Working Load Limit for easy identification and compliance.
Applications for Master Link Assemblies
Our master links are the ideal top fitting for a variety of industrial lifting slings:
Chain Slings: The standard for durable, multi-leg chain slings.
Wire Rope Slings: Used to create bridle slings with wire rope legs.
Synthetic Slings: Connects to web slings or roundslings for versatile lifting.
General Rigging: Used in construction, shipyards, manufacturing plants, and any application requiring certified overhead lifting.
