Precast Concrete Lifting Systems
Spherical Head Anchor with Collar for Precast Concrete
A cast-in lifting anchor with a spherical head and integral collar, designed for precast concrete elements requiring high tensile load distribution. The collar supports secondary tension reinforcement bars during casting, improving structural integrity under diagonal or lateral pull. Available in multiple load capacities with matching clutches and recesses for standard spherical head lifting systems. Suitable for lightweight panels, architectural cladding, and thin-walled utility modules.

Key Benefits
What Spherical Head Anchor with Collar Gives You
- The integral collar locates and supports tension reinforcement bars during concrete casting, reducing splitting risk
- Spherical head ensures secure clutch engagement even under misaligned or dynamic loads
- Distributes lateral and diagonal tensile forces deep into the reinforced concrete structure
- Improves safety during lifting and transportation of precast elements with low early-age compressive strength
- Eliminates the need for additional reinforcement or external clamps in shallow embedment applications
- Matches standard spherical head lifting clutches and recesses for compatibility with existing rigging systems
- High-strength forged steel construction ensures durability under repeated handling and field use
Application Scenarios
Where Spherical Head Anchor with Collar Is Used
- Lifting lightweight precast concrete panels during factory production and yard transfer
- Handling architectural cladding elements with thin cross-sections and limited embedment depth
- Transporting complex thin-walled utility modules where internal reinforcement is critical
- Precast element handling in low-strength concrete conditions before full curing
- Assembly of modular building systems where alignment and load distribution are key
- Site installation of precast components requiring precise positioning and secure lifting

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 Spherical Head Anchor | The collar version provides direct support for tension bars during casting, reducing splitting risk in low-strength or shallow embedment precast elements |
| Threaded Anchor with Nut | The forged collar eliminates the need for a separate nut and washer, reducing assembly complexity and potential failure points |
| Screw Pin Lifting Anchor | The solid forged construction offers higher fatigue resistance and better performance under dynamic loads compared to a screw pin design |
| Cast Anchor with Embedded Ring | The hot-forged collar ensures better load distribution and structural integrity than a cast ring, especially under lateral pull |
Use Guide
How To Use And Inspect Spherical Head Anchor with Collar
- Ensure the anchor is fully embedded in concrete before casting, with the collar aligned to tension bar positions
- Verify the spherical head matches the clutch type and recess former before lifting
- Check the working load limit stamping is legible and matches the calculated load
- Do not exceed the rated capacity under any condition, including dynamic or off-axis loads
- Inspect the anchor for deformation or marking wear before each use
- Retire the anchor if the collar shows distortion, the spherical head is damaged, or the marking is unreadable
