Grade 80 Hooks
G80 Weld On Lifting Hooks
A Grade 80 forged alloy steel lifting hook designed for permanent attachment by welding directly to a structure or piece of equipment. It provides a secure, fixed lifting point suitable for heavy-duty applications where a removable hook is not required. Available in capacities from 1T to 10T with a powder coated or painted finish, it is used in construction, manufacturing, and material handling to support Grade 80 chain slings and heavy load transfers.

Compare
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 |
|---|---|
| Removable forged lifting hook | The weld-on version eliminates the risk of loss or misplacement but cannot be reused on different equipment |
| Eye bolt with welded plate | The hook provides a more direct and secure attachment for chain slings compared to an eye bolt, which may require additional fittings |
| Swivel hook with pin | No moving parts or pin to fail under vibration, but lacks rotational freedom for dynamic load alignment |
| Lifting lug plate | The hook offers a more defined and visible lifting point with a larger contact area for sling attachment |
Use Guide
How To Use And Inspect G80 Weld on Lifting Hooks
- Verify the welded joint is fully penetrated and free of cracks before lifting
- Ensure the hook is mounted on a structurally sound base capable of supporting the full load
- Do not exceed the stamped safe working load under any conditions
- Inspect the weld and hook body regularly for signs of stress, deformation, or coating damage
- Avoid side loading or twisting the hook during use to prevent stress concentration
- Retire the hook if the weld shows signs of cracking, the body is deformed, or the marking is illegible

Answers
G80 Weld on Lifting Hooks FAQ
What is the safety factor on these weld-on hooks?
A standard 5:1 design factor is used, so the minimum breaking load is five times the stated safe working load. This meets common industrial lifting standards.
Can these hooks be welded to any steel structure?
Yes, provided the base material is compatible and the weld joint is properly prepared. The hook is designed for welding to carbon or alloy steel structures with full penetration.
Are Material Test Certificates available?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order. It confirms the material grade and mechanical properties.
What finish options are available?
Standard finish is powder coated or painted. Custom finishes such as electrophoretic black or zinc plating are available on request.
Can you stamp a custom working load limit or brand?
Yes. Custom tonnage stamping, private label marking, and OEM branding are standard options. The finish and dimensions can also be customized.
How are they packed for export?
Packed in cartons on pallets as standard. We can configure the carton count and pallet layout to match your warehouse or retail requirements.
What is the lead time for new production?
About 25 days for production plus 7 days for packing, totaling approximately 35 days before shipment. Stock items are available in 15 to 20 days.
