Precast Concrete Lifting Systems
Double-Headed U-Shape Lifting Anchor
A heavy-duty, continuous hot-forged steel anchor with symmetrical dual spherical heads, designed for the safe lifting, flipping, and transporting of precast concrete elements. Its U-shaped profile with a smooth top radius allows direct attachment of standard wire rope slings, master links, or crane shackles without requiring proprietary lifting clutches. Used across concrete pipe, utility vault, retaining wall, and highway barrier production, it delivers balanced load distribution and high shear resistance in a sin

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 |
|---|---|
| Proprietary pin anchor with ring clutch | The U-anchor eliminates the need for a clutch, reducing cost and loss risk while allowing direct rigging with standard hardware |
| Spread anchor with mechanical spreader | The U-anchor provides a simpler, more robust solution with no moving parts and better resistance to lateral shear |
| Welded lifting anchor | The continuous hot-forged construction avoids weld defects and offers higher fatigue life under repeated loading |
| Single-headed U-anchor | The double-headed version provides symmetrical load distribution and higher stability during flipping and rotation |
Use Guide
How To Use And Inspect Double-Headed U-Shape Lifting Anchor
- Ensure the stamped working load limit matches the calculated load, not the crane rating
- Hook standard slings or shackles onto the top loop—never onto the spherical heads
- Inspect the anchor for deformation or surface damage before each lift
- Use only with rigging hardware rated for the intended load and environment
- Avoid side loading or twisting the anchor during lifting or rotation
- Retire the anchor if the body shows visible deformation, the finish is compromised, or the marking is illegible

Answers
Double-Headed U-Shape Lifting Anchor FAQ
Can I use standard wire rope slings with this anchor?
Yes. The smooth, wide top radius allows direct hooking of standard wire rope slings, master links, and crane shackles without adapters.
Is there a risk of weld failure?
No. The anchor is continuously hot-forged with no welds, ensuring a monolithic steel grain path and high fatigue resistance.
What is the design factor?
A standard 5:1 design factor, so the minimum breaking load is five times the stated safe working load.
What finishes are available?
Plain steel, electro-galvanized, or hot-dip galvanized. The finish can be selected based on environmental exposure and service life requirements.
Can you provide a Material Test Certificate?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with each order on request.
Can I get custom sizes or markings?
Yes. Custom tonnage stamping, private label, OEM marking, and sizes built to a drawing are available.
How are the anchors packed for export?
Standard cartons on pallets. We can configure carton count and pallet pattern to match your warehouse or shipping requirements. Free two-month storage in Qingdao is available for shipment consolidation.
