Precast Concrete Lifting Systems
Lifting Eye Anchor / Dogbone for Precast Concrete
A forged steel lifting eye anchor, also known as a dogbone anchor, designed for embedding into precast concrete during casting. It features a looped head and wide anchoring foot to transfer load securely during vertical, horizontal, or angled lifting of thin panels, slabs, and blocks. Available from 1.3T to 20T safe working load, it provides a compact, high-strength lifting point ideal for projects with limited edge spacing or minimal concrete cover. The anchor is compatible with lifting clutches and hooks and meet

Key Benefits
What Lifting Eye Anchor Gives You
- Compact design with wide anchoring foot ensures strong mechanical grip in thin or narrow precast elements
- Looped eye head allows quick and secure connection to lifting clutches or hooks without threading
- Forged steel construction with CM490 material provides high tensile strength and impact resistance
- 3:1 safety factor ensures reliable performance under dynamic lifting loads
- Available in plain, electrogalvanized, or hot-dip galvanized finishes for corrosion resistance in varied environments
- Eliminates need for separate lifting hardware and threaded inserts in lightweight precast applications
- Suitable for vertical, horizontal, or angled lifting without compromising load transfer integrity
Application Scenarios
Where Lifting Eye Anchor Is Used
- Lifting thin precast concrete wall panels during on-site installation with limited edge clearance
- Handling modular building elements in factory production where space and weight are constrained
- Transporting narrow or thin concrete slabs and blocks with minimal concrete cover over the anchor
- Creating temporary lifting points for molds, formwork, or structural components during casting
- Installing precast units in civil engineering projects where quick and reliable lifting is required

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 |
|---|---|
| Threaded anchor | The dogbone anchor offers a simpler, all-in-one solution with no threading required, reducing installation time and risk of misalignment |
| Spherical anchor | The eye anchor is more compact and better suited for thin precast sections where space is limited, though spherical anchors allow multi-directional load transfer |
| Eye bolt | The dogbone anchor has a wider anchoring foot for better concrete interlock and load distribution, while eye bolts rely more on thread engagement and are less effective in thin sections |
| Welded lifting lug | The forged dogbone anchor has superior impact resistance and fatigue life compared to welded lugs, which can fail at the weld joint under dynamic loads |
Use Guide
How To Use And Inspect Lifting Eye Anchor
- Ensure the anchor is fully embedded in concrete with the anchoring foot flush or below the surface during casting
- Verify the loop head is fully exposed and undamaged after concrete curing before lifting
- Match the stamped safe working load to the calculated load, not the crane or winch rating
- Use only compatible lifting clutches or hooks that engage the eye loop properly
- Avoid side loading or twisting the anchor during lifting to prevent deformation
- Inspect the anchor for deformation, coating damage, or wear before each use and retire if compromised

Answers
Lifting Eye Anchor FAQ
What is the safety factor for these lifting eye anchors?
A standard 3:1 safety factor is applied, so the minimum breaking load is three times the stated safe working load.
Can I get custom sizes or anchoring feet?
Yes. Custom sizes, custom anchoring feet such as rebar anchors, and special dimensions are available upon request.
What finishes are available?
Options include plain finish, electrogalvanized, and hot-dip galvanized for improved corrosion resistance.
Are Material Test Certificates provided?
Yes. A Material Test Certificate to EN 10204 3.1 is supplied with every order upon request.
How are they marked?
Each anchor is stamped with the safe working load and material grade for traceability in the field.
Can I use this for horizontal or angled lifting?
Yes. The anchor is suitable for vertical, horizontal, or angled lifting as long as the load is within the rated capacity.
How are they packed for export?
Standard carton packing on pallets. Custom carton and pallet configurations are available to suit your warehouse or shipping needs. Free two-month storage in Qingdao is available for shipment consolidation.
