Grade 80 Hooks
G80 Eurpean Type Clevis Self-locking Safety Hook
A Grade 80 clevis self-locking safety hook made from drop-forged alloy steel, heat-treated and powder coated, designed to remain closed under load until the rear trigger is manually pressed. It connects directly to Grade 80 chain for secure rigging and prevents accidental disengagement during lifting operations. Sizes range from 6-8 to 32-8 with working load limits from 1.12T to 126T.

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Standard clevis hook without latch | The self-locking version prevents accidental disengagement but adds a moving part that requires inspection for wear |
| Screw pin hook | The clevis self-locking design is faster to engage and more secure under vibration, but the screw pin allows for finer tension adjustment |
| Screw pin safety hook | The self-locking clevis is more reliable under continuous vibration and faster to use, but the screw pin offers a tighter closure for high-tension applications |
| Soft shackle | Steel hook handles abrasion and high loads better than a soft shackle, but is heavier and less flexible in dynamic setups |
Use Guide
How To Use And Inspect G80 Eurpean Type Clevis Self Locking
- Verify the stamped WLL matches the calculated load before use
- Ensure the trigger mechanism moves freely and the latch closes securely
- Do not force the hook open if the latch is jammed or the trigger is stiff
- Inspect the hook for deformation, wear on the latch, or coating damage before each use
- Never exceed the rated WLL even if the hook appears intact
- Retire the hook if the body shows bending, the latch fails to close, or the marking is illegible

Answers
G80 Eurpean Type Clevis Self Locking FAQ
What is the safety factor for this hook?
A standard 4:1 design factor, so the minimum breaking load is four times the stated safe working load.
Can this hook be used with Grade 80 chain?
Yes. The clevis design allows direct mechanical connection to Grade 80 chain for secure and reliable rigging.
What certificates are provided with the order?
A Material Test Certificate to EN 10204 3.1 is supplied on request. Every batch is proof load tested with dimensional and breaking strength checks recorded.
Is the powder coating durable in harsh environments?
Yes. The powder coat finish resists corrosion from salt, moisture, and industrial exposure, but it should be inspected regularly for damage.
Can you customize the tonnage marking and branding?
Yes. Custom tonnage stamping, private label marking, and OEM packaging are standard options, with finishes available in powder coated, zinc plated, or electrophoretic black.
How are the hooks packed for export?
