Grade 100 Master Link with Integrated Shortening Hooks, MLD type

No.505029

The Grade 100 Master Link with Integrated Shortening Hooks (MLD Type) is a specialized top rigging component engineered specifically for 2-leg chain sling assemblies.

  • Fully Integrated Design: Combines a solid master link with two built-in eye grab hooks, removing the need for separate connecting links and reducing overall sling weight.
  • Dual-Purpose Hooks: The integrated grab hooks function as both direct chain connectors and efficient shortening hooks for quick leg length adjustments.
  • Grade 100 Performance: Manufactured from premium alloy steel, delivering 25% higher lifting capacity compared to standard Grade 80 components.
  • Size & Capacity Range: Available for chain sizes from 6mm to 16mm, supporting Working Load Limits (WLL) ranging from 2 tons up to 14 tons.

Product Features

  • Dedicated 2-Leg Design: Specifically engineered to streamline the assembly of Adjustable 2-Leg Chain Slings. The integrated hooks allow for immediate length adjustment of both legs.
  • Integrated Efficiency: Combines the master link and two shortening hooks into a single forged component. Eliminates the need for separate connecting links and grab hooks, reducing assembly time and parts cost.
  • Headroom Saver: By integrating the components, the effective length of the top assembly is minimized, providing maximum lifting height in low-headroom environments.
  • Grade 100 Alloy: Constructed from high-strength Grade 100 steel, offering 25% higher capacity than comparable Grade 80 assemblies while being significantly lighter.
  • Secure Chain Grip: The integrated grab hooks are designed to fully support the chain link, ensuring safe load transfer without reducing the chain's Working Load Limit.
  • Standard: Complies with ASTM A952 and EN 1677 standards.

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.
