How to Install Lifting Anchors Safely in Precast Concrete Panels

Incorrect installation of lifting anchors can be disastrous-causing cracked panels, site accidents, or even lifting failures. Yet, with the right methods, you can ensure structural integrity, worker safety, and smooth precast handling. In this guide, we'll break down the safe and correct way to install lifting anchors in precast concrete panels. Whether you're new to precast or managing hundreds of lifts a week, this is your go-to safety checklist!

Lifting Anchor

Why Are Lifting Anchors Essential?

Lifting anchors provide secure, embedded connection points, ensuring that precast elements remain stable and do not crack or shift during lifting, thereby maintaining structural integrity throughout transportation and installation. Lifting anchors are designed to safely transfer loads from lifting equipment to concrete units, taking into account weight, lifting angle, and rigging forces.

Types of Anchors and Their Applications

Spherical head anchors – Ideal for rapid, safe lifting with universal lifting clutches.

Threaded anchors – Versatile and reusable, great for adjustable connections.

Pin anchors – Simple and cost-effective, often used for light-duty or temporary lifting.

Flat plate anchors – Designed for thin elements or where surface finish matters.

Pre-Installation Checklist

Before installing lifting anchors in precast concrete, proper preparation is key to ensuring structural safety and lifting efficiency. Here's your essential checklist:

Review Construction Drawings & Specifications

Double-check all technical drawings, lifting plans, and anchor specifications. Look for required anchor types, positions, and load ratings to prevent on-site conflicts or delays.

Choose Correct Anchor Positions & Spacing

Anchor placement must match the panel's center of gravity and lifting orientation. Incorrect spacing can cause tilt, rotation, or even panel failure during lifting.

Prepare Materials in Advance

Gather all required components: lifting anchors, recess formers, reinforcing bar templates, and sleeves. Ensure compatibility and quality compliance.

Gather Required Tools

Use precise tools like laser distance meters and levels. Don't forget safety gear (helmets, gloves, vests) and installation aids like fixing jigs or spacers.

Common Mistakes to Avoid

Placing Anchors Too Close to the Panel Edge

This weakens the concrete, increasing the risk of cracks or breakouts during lifting-always maintain proper edge distance.

Incorrect Anchor Angles

Angles that don't align with the lift direction introduce shear stress, causing anchor failure or dangerous panel swings.

Poor Integration with Reinforcement

Anchors must tie into the rebar cage. If not, they may pull out under load-especially in thin or narrow panels.

Improper or Missing Recess Formers

Recesses enable easy lifting clutch connection. If omitted or misaligned, workers may struggle during rigging or cause damage.

No Marking or Traceability After Curing

Once cured, unmarked anchors are hard to locate-use color tags or surface markings for post-pour identification.

Lifting anchors are critical components in precast concrete construction, ensuring safe handling, transportation, and installation of precast elements. The pre-installation checklist highlights the need to review drawings, ensure accurate anchor locations, prepare all materials, and use the proper tools and safety equipment. By following these steps and avoiding mistakes, the team can ensure safe lifting operations and maintain the quality of all precast elements.
