Grade 80 Eye Foundry Hook EFK type

No.502019

The Grade 80 Eye Foundry Hook (EFK Type) features a wide throat opening designed for foundries and pipe handling. It easily engages large or irregular loads where standard hooks cannot fit.

  • Wide Throat Opening: Latch-free, oversized mouth allows quick attachment to bulky items, molds, and large-diameter pipes.
  • High-Strength Alloy: Forged from quenched and tempered Grade 80 steel for maximum durability in heavy industrial use.
  • Certified Safety: Proof-load tested with a strict 4:1 safety factor and clearly marked Working Load Limits (WLL).
  • Corrosion Resistant: Features a durable powder-coated finish for extended life in demanding work environments.

Grade 80 Eye Foundry Hook - EFK Type

Wide Throat & Latch-Free Design for Oversized Loads
Grade 80 Alloy Steel Extra Wide Throat Foundry Application 4:1 Safety Factor
Grade 80 Eye Foundry Hook EFK

*Designed for large diameter loads and high-heat environments

Product Features

  • Extra Wide Throat: Features a significantly larger throat opening than standard hooks. Allows connection to large diameter bars, casting molds, and trunnions where standard hooks cannot fit.
  • Foundry Ready: Ideal for sorting duties and high-heat foundry operations. The lack of a safety latch prevents mechanism failure caused by dirt, slag, or extreme heat.
  • Eye Connection: The eye top allows for versatile connection to chain slings (via Connecting Links), wire rope slings, or synthetic lifting belts.
  • Robust Material: Forged from Grade 80 Alloy Steel, Quenched and Tempered. The robust tip is engineered to withstand incidental contact (though tip loading should be avoided).

Grade 80 Chain Fittings

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.
