Grade 80 Recessed Link

No.502057

This Grade 80 Forged Alloy Recessed 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

Alloy Steel Lift Ring (Recessed)

Grade 80 Engineered Master Link with Machined Flats
Grade 80 Alloy Steel Recessed Design 5:1 Safety Factor

The Alloy Steel Lift Ring is a critical component for specialized lifting operations. It features unique "recessed" or "flatted" cutouts integrated into its design. These machined sections are engineered specifically to securely accommodate connecting hardware, such as "boss hooks," "G-hooks," or Omega links, offering superior flexibility and safe assembly for complex rigging needs.

Product Features & Technical Advantages

🛡️

Premium Alloy Steel

Manufactured from high-quality alloy steel, rigorously quenched and tempered to exceed Grade 80 strength and toughness requirements.

⚙️

The "Flatted" Advantage

The recessed section is precisely machined to allow for the easy attachment of G80 Connecting Links (Omega links). This is vital when the standard link thickness would otherwise prevent the connector's safety gate from fully closing.

🎨

High Visibility Finish

Treated with industrial plastics spraying (powder coating), available in safety red (RAL 3020) or yellow (RAL 1003) for instant identification and enhanced corrosion resistance.

🔍

100% Traceability

Each link is permanently embossed with its physical size, grade (80), and a unique manufacturer batch code to ensure 100% traceability during mandatory safety audits.

Manufacturing & Quality Control Standards

To ensure absolute safety in the field, every lift ring undergoes a strenuous testing protocol before leaving the facility.

🔗 System Compatibility

  • Forged from special alloy steel with high intensity and high toughness, then heat-treated.
  • Designed to seamlessly integrate with synthetic slings and G80 lifting chains.
  • Fully meets and complies with the stringent EN818-2 standard for lifting applications.

🔬 The Testing Protocol

  • Proof Load: Each workpiece is individually tested at 2.5 times its Working Load Limit (WLL).
  • Fatigue Testing: Rigorous sampling involves 20,000 cycles of dynamic fatigue testing.
  • Destructive Testing: Strict sampling and physical breakage testing is executed for every production batch.
  • Flaw Detection: 100% magnetic powder flaw detection is utilized to identify microscopic surface cracks.
  • Hardness Verification: 100% of the pins are tested to guarantee uniform metallurgical hardness.

⚖️ Critical Safety Factor

This specific Alloy Steel Lift Ring is engineered and certified with an Ultimate Load (Minimum Breaking Strength) that is 5 times its Working Load Limit (WLL). This exceptional 5:1 Safety Factor provides a massive margin of safety for demanding industrial lifts.
