Grade 80 Sliding Choke Hook SCH type

No.502027

The Grade 80 Sliding Choke Hook (SCH Type) is a specialized rigging component designed specifically to create secure choker hitches. It slides freely along the length of a chain, wire rope, or synthetic sling to tightly grip and secure bulky or awkwardly shaped loads.

  • Choker Hitch Design: Engineered to slide smoothly along the sling, allowing the assembly to quickly and tightly choke around loads for secure lifting and material handling.
  • High-Strength Material: Forged from premium quenched and tempered Grade 80 alloy steel, providing exceptional durability and resistance to wear.
  • Certified Safety: Fully compliant with EN 1677 standards, offering a reliable 4:1 safety factor and proof-load tested to 2.5 times the Working Load Limit (WLL).
  • Corrosion Protection: Finished with a durable powder coating that significantly enhances corrosion resistance in harsh industrial environments.

*Slides along chain to tighten around logs or pipes

Product Features

  • Sliding Choke Function: Specifically designed to slide freely along the chain leg. When lifted, the hook naturally tightens around the load, securing loose items like logs and pipes.
  • Direct Clevis Connection: Features an integral Clevis Pin that connects directly to the chain link. This eliminates the need for an intermediate Connecting Link, reducing cost and weight.
  • Optimized Throat: The wide throat is shaped to accommodate chain link dimensions, minimizing friction and wear during the sliding action while ensuring a secure grip.
  • High Durability: Forged from Grade 80 Alloy Steel, Quenched and Tempered. Built to resist abrasion and shock loads common in forestry and bundling applications.

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

  • 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.
