Grade 80 Shortening Clutch Locking Type SCL type

No.502023

The Grade 80 Shortening Clutch Locking Type (SCL Type) safely adjusts chain sling lengths. Its integrated safety pin firmly locks the chain in place, preventing accidental release even when the load is slack.

  • Locking Safety Pin: Securely locks the engaged chain link to prevent accidental disengagement.
  • 100% WLL Retention: The clutch design cradles the chain, allowing the sling to safely maintain 100% of its rated lifting capacity.
  • Direct Attachment: Built-in clevis pin allows for quick connection to Grade 80 chains without extra coupling links.
  • High-Strength Forging: Made from quenched and tempered Grade 80 alloy steel for maximum durability and strength.

Product Features

  • Positive Locking: Features a spring-loaded Locking Pin. Once the chain is seated, the pin locks it securely, preventing accidental disengagement due to vibration or slack lines.
  • 100% Load Capacity: The clutch pocket fully cradles the chain link, preserving its structural integrity. This allows the sling to be used at full capacity, unlike grab hooks that often require a 20% reduction.
  • Clevis Connection: Designed with an integral clevis pin for direct attachment to the chain leg or master link, ensuring a compact and robust assembly.
  • Safety Design: The locking mechanism is recessed to protect it from damage. Forged from Quenched and Tempered Grade 80 Alloy Steel.

Type Security Why Choose This?
Shortening Clutch
(SCL / This Product)
Locking Pin Maximum Safety.
Chain cannot accidentally fall out. Ideal for critical lifts or when the chain might go slack.
Grab Hook
(CGS / EGS)
Open Throat Speed & Cost.
Faster to adjust (just drop the chain in), cheaper, but chain can slip out if not under tension.

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.

  • 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.
