Grade 80 Pear Shaped Master Link MLP type

No.502057

This Grade 80 Forged Alloy Pear Shaped Master Link is an essential component designed for secure, heavy-duty lifting and material handling in rigorous industrial, construction, and rigging environments.

  • Heavy-Duty Forged Alloy Steel: Manufactured from quenched and tempered Grade 80 alloy steel to provide high strength and impact resistance for demanding overhead lifting.
  • Excavator & Rigging Application: Frequently used as an excavator lift point or as the central attachment hub in both single and multi-leg chain sling configurations to balance loads securely.
  • High Safety Standards: Meets strict EN 1677 specifications for overhead lifting, typically tested with a reliable 5:1 Working Load Limit (WLL) safety factor.
  • High-Visibility Anchor Point: Often painted yellow or coated for traceablility and visibility, providing a clearly identifiable, secure connection point for heavy rigging operations.

Technical Data

Grade 80 Pear Shaped Master Link

This premium Grade 80 Forged Alloy Steel Pear Shaped Master Link (featuring integrated sublink & machined flats) is engineered explicitly for secure overhead lifting, heavy-duty rigging configurations, and complex multi-leg chain sling assemblies where precise component integration is required.

  • Drop Forged Alloy Steel: Precision structural integrity achieved through controlled quenching and tempering process for superior fatigue strength.
  • Optimized Recessed Geometry: Machined flats on the inner arches seamlessly accept G-hooks, boss hooks, or Omega connectors without joint restriction.
  • High Regulatory Compliance: Manufactured in strict accordance with EN1677-4 specifications for lifting sling structural fittings.
  • Structural Sublink Functionality: Pre-separated double-aperture structure divides crane attachment loops from lower sling links to avoid bunching.

Technical Advantages & Design Features

Engineered Recessed Flat Section

The specialized "flatted" zones solve a common field problem: standard thickness chain attachments occasionally jam safety latches. The precise reduction depth guarantees clean clearance for safety gates to seal fully.

Industrial Anti-Corrosion Protection

Coated with durable, thermoset plastic powder spraying. Standard colorways include high-visibility Safety Red (RAL 3020) and Safety Yellow (RAL 1003) for easy identification on worksites.

Uncompromised Operational Traceability

Deep-embossed metal stamp markings include Working Load Limit (WLL), Grade specification (G80), Nominal Size parameters, and traceable manufacturer forge codes for inspection standard maintenance.

Manufacturing Validation Protocols

  • Proof Load Testing: Each component is verified individually up to 2.5 times its designated Working Load Limit (WLL).
  • Cyclic Fatigue Evaluation: Pre-production structural fatigue assessment qualifies through 20,000 cycles at a designated high-stress range.
  • Non-Destructive Testing: 100% Magnetic Particle Inspection (MPI) ensures zero microscopic fissures or surface defects.
  • Safety Factor Threshold: Rated with an optimized minimal breaking threshold exceeding a 5:1 factor scale ratio.
