Grade 80 Hooks
G80 Swivel Self Locking Hook European Type
A drop-forged alloy steel swivel self-locking hook designed to European Type standards, with a trigger-activated locking mechanism that prevents accidental disengagement. The swivel action allows free rotation to align with the load, reducing sling twist and improving safety during lifting. Available from 6-8 to 32-8 in size, with a 4:1 safety factor, powder coated or painted finish, and suitable for EN818-2 G80 chain.

Key Benefits
What G80 Swivel Self Locking Hook European Type Gives You
- Swivel action allows the hook to rotate freely, reducing rope or sling twist during lift and load movement
- Self-locking mechanism prevents accidental disengagement under load, during lowering, or when stationary
- Trigger-activated opening ensures the hook remains closed until intentionally opened, enhancing field safety
- Drop-forged alloy steel body with quench and temper treatment provides high strength and impact resistance
- 4:1 safety factor ensures minimum breaking load is four times the stated working load limit
- Powder coated or painted finish resists corrosion in industrial and outdoor environments
- Compatible with EN818-2 G80 chain, ensuring consistent performance in high-duty lifting applications
Application Scenarios
Where G80 Swivel Self Locking Hook European Type Is Used
- Lifting operations in construction sites where load orientation changes during hoisting and rotation is required
- Material handling in ports and warehouses where slings must not twist under dynamic load shifts
- Rigging setups on cranes and hoists where a secure, self-locking hook prevents accidental release
- Offshore and marine applications where vibration and movement increase the risk of hook disengagement
- Industrial maintenance where equipment is lifted and repositioned frequently with minimal setup time
- Heavy lifting in mining and energy projects where chain and hook compatibility with EN818-2 is mandatory
Who It Is For
Buyers This Product Is Built For
- Construction and rigging contractors specifying reliable, self-locking hooks for crane and hoist operations
- Industrial maintenance teams requiring hooks that stay closed under vibration and dynamic load
- Ports and logistics operators handling containerized or heavy cargo with chain slings
- Manufacturers of lifting equipment integrating certified hooks into their rigging kits
- Rigging distributors stocking European Type hooks with traceable safety features and consistent performance
Problems It Solves
Problems This Product Removes
- Accidental load release from a hook during lifting or lowering due to unsecured gate or vibration
- Sling or chain twisting caused by fixed hook orientation during load movement
- Need for multiple hook types to handle both swivel and locking functions separately
- Lack of compatibility with EN818-2 G80 chain in standard hook designs
- Inadequate safety factor or unclear marking on hooks used in high-duty lifting environments
- Corrosion damage in outdoor or marine environments due to poor surface finish on lifting hardware

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 non-swivel hook | The swivel version reduces sling twist and load misalignment but adds a moving part that requires inspection for wear |
| Fixed gate hook | The self-locking trigger gate prevents accidental opening but requires more effort to open than a simple gate |
| Screw pin hook | The swivel self-locking hook is more secure under vibration and does not require a cotter pin, but is heavier and more complex |
| Soft shackle | Steel hook offers better abrasion resistance and load capacity, while a soft shackle is lighter and floats but fails under sharp edges |
Use Guide
How To Use And Inspect G80 Swivel Self Locking Hook European Type
- Verify the stamped working load limit matches the calculated load, not the hoist rating
- Ensure the trigger gate is fully closed and locked before lifting any load
- Inspect the swivel mechanism for free rotation and absence of grit or binding before use
- Do not use if the gate shows deformation, the swivel is seized, or the marking is illegible
- Keep the load aligned with the hook axis to avoid side loading and premature wear
- Retire the hook if the locking mechanism fails to engage or the body shows cracks or distortion

Answers
G80 Swivel Self Locking Hook European Type FAQ
What is the safety factor on this hook?
A standard 4:1 design factor, so the minimum breaking load is four times the stated safe working load.
Is this hook compatible with EN818-2 G80 chain?
Yes. It is designed for use with EN818-2 G80 chain and meets the required strength and dimensional standards.
Can the gate be opened accidentally during lifting?
No. The trigger-activated self-locking mechanism prevents opening unless the gate is manually pressed, reducing the risk of accidental disengagement.
What finishes are available?
Standard finish is powder coated or painted. Custom finishes including electrophoretic black are available on request.
Can you provide a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with the order on request.
What sizes are available?
The size range runs from 6-8 to 32-8, with working load limits from 1.12T to 31.5T. Full dimensions are listed in the specs table.
How are the hooks packed for export?
Packed in cartons, then palletized. We can configure carton count and pallet pattern to suit your warehouse or retail pack. Free two-month storage in Qingdao is available for shipment consolidation.
