Double-Headed U-Shape Lifting Anchor

Product Overview

The Double-Headed U-Shape Lifting Anchor (commercially recognized as the U-Anchor, Precast U-Anchor, Double-Headed Anchor) is a premier, heavy-duty solution designed for the safe handling, flipping, and transporting of diverse precast concrete elements. Engineered through precision continuous hot-forging, this high-integrity U-anchor features a symmetrical arched profile capped with two standard spherical heads at its insertion feet.

The primary engineering advantage of this Double-Headed Anchor lies in its uncompromised universal versatility. Unlike proprietary pin or spread anchor systems that mandate specialized, costly mechanical lifting clutches, the smooth, generous top radius of the U-Shape Lifting Anchor allows rigging crews to hook standard wire rope slings, master links, or general crane shackles directly onto the embedded loop. It is the ideal wholesale hardware choice for precast yards optimizing operational costs in manufacturing concrete pipes, utility vaults, retaining wall blocks, and highway barriers.

Key Features of U-Shape Lifting Anchor

• Clutch-Free Lifting Efficiency: Completely eliminates the procurement, logistics, and loss overhead associated with dedicated ring clutches. Standard rigging equipment hooks directly onto the exposed loop, streamlining site operations.

• Symmetrical Dual-Head Anchorage: The double-headed structural feet independent anchor deep within the concrete casting zone, distributing forces symmetrically and generating a highly efficient, balanced concrete failure cone.

• Premium Monolithic Forged Construction: Hot-forged from high-grade structural round bars with zero welding points. This continuous steel grain path guarantees exceptional structural ductility, high fatigue life, and resilience against dynamic snubbings.

• Optimized Edge Distance & Shear Performance: Due to its double-leg rigid framework, this anchor delivers exceptional linear lateral shear resistance, making it perfect for tilting and rotating slim precast wall panels.

• Industrial Anti-Corrosion Finishes: Available in raw plain steel, durable electro-galvanized (zinc-plated) coat, or heavy Hot-Dip Galvanized (HDG) processing to survive harsh seasonal yard storage and marine exposure environments.

Technical Specifications

Our Double-Headed U-shape Lifting Anchor series is manufactured and load-tested in strict compliance with international rigging safety guidelines, providing a consistent 5:1 design safety factor across all configurations.

Customization & OEM Support: As a dedicated factory-source supplier of concrete accessories, we provide comprehensive custom manufacturing. If your engineering blueprints demand extended leg lengths, specific inner radius bends, or custom metric load stamps, our production lines can forge to your exact specification sheets.

Installation & Application Protocol

1. Formwork Attachment: Position the Double-Headed U-Shape Lifting Anchor inside the mold. Secure the two forged spherical heads downward into the reinforcement rebar mesh, while the curved apex faces the designated lifting plane.

2. Recess Assembly: Cover the curved apex loop with a matching reusable rubber or plastic recess former. This ensures a clean, smooth, concrete-free pocket is maintained around the hook point during casting.

3. Pouring & Curing: Cast the concrete mixture. Utilize proper mechanical vibration to fully consolidate aggregates around both forged anchor heads, eliminating potential air structural voids.

4. Stripping & Rigging: Once the concrete reaches stripping strength, remove the formwork and pop off the recess former. Pass your standard site crane hook or wire rope sling directly through the now-exposed steel arc loop for safe transport.

The U-Shape Lifting Anchor is widely used in precast concrete production, including:

• Precast wall panels
• Concrete beams and columns
• Slabs and flooring systems
• Pipe and utility structures
• Bridge and infrastructure components
• Architectural precast elements
• Industrial precast concrete products

It provides a reliable lifting point for safe handling during manufacturing, storage, transport, and installation.

Frequently Asked Questions (FAQs) for Procurement Teams

Q1: Does this anchor require specific recess formers?

Yes. To ensure standard hooks can easily pass through the concrete surface, we manufacture and supply custom-fit reusable Rubber Recess Formers designed to match the specific dimensions of each load class in our U-anchor portfolio.

Q2: Can the U-Shape Lifting Anchor be used for edge-lifting wall panels?

Absolutely. Thanks to its dual-leg design, this anchor spreads tension loads over a wider plane compared to single-pin anchors, making it highly effective for edge-lifting and tilting operations where lateral shear forces are prevalent.

Q3: What material certifications do you provide for customs clearance?

We provide a complete documentation package, including Raw Steel Mill Test Certificates (showing exact chemical composition), internal destructive tensile test records, and batch-wise quality inspection stamps.
