No.505022

The Grade 100 Master Link Assembly (MLY Type) is a heavy-duty top rigging terminal consisting of a main master ring and two intermediate sub-links, engineered primarily for 3-leg and 4-leg lifting chain slings.

Sub-Link Design: The addition of two sub-links prevents overcrowding on the main ring, allowing multiple chain legs or sling components to move freely and distribute weight evenly.
Grade 100 Capacity: Constructed from premium quenched and tempered alloy steel, offering up to 25% more lifting capacity than Grade 80 equivalents of the same size.
Wide Size Range: Accommodates chain sizes from 6mm to 32mm, with impressive Working Load Limits (WLL) starting at 3 tons and scaling up to 85 tons for heavy industrial lifting.
Standard Compliance: Designed to meet EN1677 standards, featuring a durable powder-coated finish and rigorously proof-load tested to ensure maximum safety.

Grade 100 Oversized Master Link Assembly - MLY Type

For Large Crane Hooks (3 & 4 Leg Slings)

Grade 100 Alloy Steel Oversized Top Ring For 3-Leg & 4-Leg Slings Engineered Flats

*Extra wide top ring for large crane hooks

Product Features

Oversized Top Ring: The main master link features extra-wide internal dimensions, specifically designed to fit over large crane hooks (DIN 15401), Ramshorn hooks, and heavy-duty lifting points that standard assemblies cannot accommodate.
3 & 4 Leg Application: Comes pre-assembled with two intermediate links, making it the ready-to-use top component for constructing 3-Leg and 4-Leg Grade 100 Chain Slings.
Engineered Flats: The main ring features forged flat sections to allow the intermediate links to articulate freely, ensuring proper load distribution across the legs.
Grade 100 Strength: Manufactured from high-strength Grade 100 Alloy Steel, offering 25% higher lifting capacity than Grade 80 equivalents, ideal for heavy-lift projects where weight reduction is critical.
Proof Tested: Individually proof tested to 2.5 times the Working Load Limit.
Standard: Compliant with ASTM A952 and EN 1677-4 performance standards.

Assembly Selection: Standard vs. Oversized

Model	Top Ring Size	Best For
Oversized (MLY) (This Product)	Extra Wide/Long	Large Crane Hooks. Use this when your crane hook (e.g., Ramshorn) is too wide for a standard ring.
Standard (MAE) (Regular Assembly)	Standard Metric	Standard Hooks. Use this for standard overhead cranes. More compact and cost-effective.

Grade 100 Sling Components are high-strength alloy steel lifting accessories designed for heavy-duty lifting applications. Compared with Grade 80, Grade 100 offers higher working load limits (WLL) at the same size, or the same WLL with a smaller, lighter component.

What Does "Grade 100" Mean?

High-Strength Alloy: Heat-treated, quenched, and tempered steel.
Increased Capacity: Typically 25% higher WLL than Grade 80.
Safety Factor: Minimum breaking force ≈ 4 × WLL.
Standards: EN 818-4 / EN 818-6, ASTM equivalents.

Identification & Markings

Every Grade 100 component must be clearly marked with:

Grade: G100 or 10
Manufacturer's Mark
Size or WLL
Traceability Code (Batch / Heat Number)

⚠️ Safety & Compatibility Warning

❌ NEVER mix Grade 100 with Grade 80 components in the same sling assembly.
✅ Use only Grade 100 chain + Grade 100 fittings together.
Regularly inspect for wear (>10%), cracks, deformation, heat damage, or corrosion.
