Grade 80 Omega Link OML type

No.502003

The Grade 80 Omega Link (OML Type), also known as a bow coupling link, is an essential forged connecting fitting. It is specifically designed with a flat tapered section to easily connect Grade 80 lifting chains to master links, eye hooks, and thimbles without welding.

  • Wider Clearance: Features an extended "omega" (horseshoe) shape that provides wider internal clearance than standard connectors, accommodating larger hooks, master rings, or multiple chain legs.
  • Easy Assembly: Engineered with a removable load pin and locking mechanism, allowing for fast, secure, and mechanical field assembly of chain slings and rigging hardware.
  • Heavy-Duty Forging: Manufactured from premium quenched and tempered Grade 80 alloy steel in strict compliance with EN 1677 safety standards.
  • Certified Reliability: Rigorously proof-load tested to 2.5 times the Working Load Limit (WLL) and features a standard 4:1 safety factor for demanding overhead lifts.

Bow Coupling Link for Wider Connections
Grade 80 Alloy Steel Omega (Bow) Profile Hammerlock Style EN 1677-1
Grade 80 Omega Link OML Type

*Wider internal clearance than standard connectors

Product Features

  • Optimized Shape: Features a unique Omega (Ω) / Bow profile that provides a larger internal clearance compared to standard connecting links. Ideal for connecting chains to wide hooks, shackles, or lifting points.
  • Chain End Fitting: Primarily designed as a robust chain end fitting, allowing for secure attachment of components that might not fit a standard hammerlock.
  • Easy Installation: Utilizes a load pin and retaining sleeve design for quick, hammer-lock style assembly on site.
  • Heavy-Duty Material: Forged from high-quality Quenched and Tempered Alloy Steel (Grade 80). Each batch undergoes Proof Load Testing at 2.5x WLL.

G-80 Alloy Fittings / Grade 80 Sling Components

Grade 80 Sling Components are the long-established industry standard for chain slings and heavy lifting. Fully compliant with international lifting regulations and designed for durability.

What Does “Grade 80” Mean?

  • High-strength Alloy Steel
  • Min breaking force ≈ 4 × WLL
  • Heat-treated (Quenched & Tempered)
  • Standard: EN 818-4 / EN 818-6
  • Marked “G80” or “8”

Common Grade 80 Components

1. Master Links

Used to connect the sling to a crane or hoist hook.

  • Master Link (ML)
  • Master Link Assembly (Multi-leg)
  • Pear-shaped master links

2. Hooks

End fittings for secure load attachment.

  • Clevis Self-Locking Hook
  • Eye Self-Locking Hook
  • Sling Hook with Safety Latch
  • Foundry Hook
  • Grab Hook (Shortening)

3. Connecting Links

Essential hardware to join chains or fittings.

  • Clevis Connecting Link
  • Hammerlock / Coupling Link
  • Repair Link (Special use only)

4. Chain & Adjusters

The core lifting medium and adjustment tools.

  • Grade 80 Alloy Chain (Marked G80)
  • Shortening Clutch
  • Swivel (Bearing/Non-bearing)
  • Lifting Rings

Typical Applications

  • Chain slings (1 to 4 legs)
  • Construction & Civil Works
  • Manufacturing & Workshops
  • Steel Fabrication
  • General Industrial Lifting

Identification Marks

  • Grade: G80 / 8
  • Manufacturer’s ID
  • Size or WLL (Working Load Limit)
  • Traceability Batch Code

Grade 80 vs. Grade 100

Feature Grade 80 Grade 100
Strength Level Standard Industry Standard +25% Higher
Component Size Larger Smaller (for same WLL)
Weight Heavier Lighter
Cost More Cost-Effective Higher

⚠️ Safety & Compatibility Notes

  • DO NOT mix Grade 80 components with other grades (G70, G100) in the same sling leg.
  • Always match Grade 80 chain with Grade 80 fittings.
  • Observe sling angle factors and WLL reductions during lifts.
  • Inspect regularly for: Wear (>10%), Cracks/Distortion, Corrosion, or Heat Damage.
