Grade 80 Links
Weld-on pivoting link / Grade 80 Weld on Lifting Point
A Grade 80 forged steel weld-on pivoting link designed for overhead lifting with a 4:1 design factor. It features a pivoting bail that allows load alignment during lifting, reducing side loading and improving safety. Available in sizes from 1.12T to 15T WLL, with dimensions and weights provided for each capacity. The link is drop forged, quenched and tempered, and finished with a painted surface for corrosion resistance. It is intended for permanent attachment to structural components via welding.

Problems It Solves
Problems This Product Removes
- Lack of a fixed, permanent lifting point on fabricated steel structures requiring crane access
- Side loading on rigid lifting eyes due to misalignment during hoisting

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 |
|---|---|
| Fixed eye bolt | The pivoting link allows load alignment and reduces side loading, but a fixed eye bolt is simpler and cheaper for static, aligned lifts |
| Rigid weld-on eye | The pivoting design reduces stress on the weld joint during off-axis lifting, but a rigid eye has no moving parts and is easier to inspect |
| Screw pin shackle | The weld-on link is permanent and secure, but a shackle allows for quick attachment and removal |
| Swivel eye bolt | The swivel offers rotation but is typically lower capacity; this link has higher strength and a more robust base for welding |
Use Guide
How To Use And Inspect Weld-On Pivoting Link
- Inspect the weld-on link and base for cracks, wear, or deformation before each use
- Ensure the workpiece surface is clean and flat to allow full contact with the base
- Do not use spacers between the link and the mounting surface
- Verify the pivot bail rotates freely and is not seized or bent
- Weld only using qualified welders and approved procedures to maintain structural integrity
- Do not exceed the stamped WLL or use the link for dynamic or shock loading without engineering review

Answers
Weld-On Pivoting Link FAQ
What is the design factor for this weld-on pivoting link?
A standard 4:1 design factor, so the minimum breaking load is four times the stated safe working load.
Can this link be used on a dynamic or shock load?
It is rated for overhead lifting under controlled conditions. Shock or dynamic loads require engineering evaluation and may reduce safe working load.
What welding procedures are recommended?
Use qualified welders and approved procedures. The base must be fully in contact with the workpiece with no gaps or spacers.
Is a Material Test Certificate available?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order upon request.
Can the link be painted or coated differently?
Yes. Custom finishes including zinc plating, powder coating, or electrophoretic black are available on request.
What should I check before using the link?
Inspect for cracks, wear, deformation, or damage to the bail or base. Ensure the pivot moves freely and the weld is intact.
How is it packed for export?
Standard carton and pallet packing. We can configure the packing to match your warehouse or retail requirements. Free two-month storage in Qingdao is available for shipment consolidation.
