Everything You Need to Know About Lifting Anchor Systems

In the precast concrete industry, details determine success or failure—especially when it comes to lifting and handling heavy components. Whether installing wall panels, beams, columns, or bridge sections, you need reliable equipment. One of the most important tools is the lifting anchor system.

Lifting anchor systems may not be the first thing you think of during project planning, but they play a vital role in safety, construction efficiency, and cost control. Therefore, understanding how these systems work, how to choose the right product, and why selecting the right supplier is equally important is essential for every practitioner.

In this article, we will provide a comprehensive analysis of the components of a lifting anchor system, including safe operation tips and supplier selection criteria, to help you make more informed decisions on your projects.

Why Lifting Anchor Systems Are So Important

Precast concrete is widely popular for its durability, precision, and construction efficiency. However, transporting these large, heavy components from the factory to the construction site and then precisely installing them is no easy task.

The role of a lifting anchor system is to ensure that every precast component is lifted safely and accurately. Without a reliable system, completing a construction project can be difficult. The quality of the lifting system often directly determines the success of the installation process.

From multi-story residential buildings to infrastructure projects like bridges and tunnels, lifting anchor systems are essential "behind-the-scenes" components in construction.

What is a lifting anchor system?

Simply put, a lifting anchor system is a hardware system used to safely lift, transport, and install precast concrete components.

It typically includes:

Lifting anchors—embedded during the concrete pour

Lifting clutches—connect the lifting equipment to the anchors

Rubber recess formers & magnetic recess formers—create precise anchor recesses

The working principle is to place the anchors on the lifting anchors before pouring concrete. Ensure they are correctly positioned and securely fixed, then pour and cure. After curing, the rubber recess former is removed, revealing a clean recess for installing the lifting clutch. During lifting, the hook or eye is connected to the anchors, and the components are transported using equipment such as a crane.

Main Components of a Lifting Anchor System

Lifting Anchor

Lifting anchors come in a variety of shapes, sizes, and load capacities, and can be made of carbon steel or stainless steel, depending on the requirements. Common types include lifting pin anchors, spherical double-headed lifting anchors, lifting eye anchors, and V-anchor lifting anchors. When selecting an anchor, consider the load-bearing requirements, concrete strength, and specific application.

Lifting Foot Anchors

Lifting foot anchors feature a flat base plate designed for secure embedding in precast concrete. Their robust construction ensures stable load distribution and reliable lifting performance. Ideal for heavy or irregularly shaped components, they provide excellent resistance to pulling forces and facilitate safe handling during transport and installation.

Spherical Double-Headed Lifting Anchors

Spherical double-headed lifting anchors consist of two rounded heads connected by a central shank, enabling multidirectional load-bearing capacity. This design allows for versatile lifting angles while maintaining high strength. They are commonly used in complex precast elements requiring flexible rigging solutions without compromising safety.

Lifting Eye Anchors

Lifting eye anchors feature a closed-loop “eye” integrated into the anchor body, allowing easy attachment of lifting hooks or slings. Manufactured from high-strength steel, they provide secure and reliable connections. Their straightforward design simplifies installation and is widely used for standard precast component lifting tasks.

V-Anchor Lifting Anchors

V-anchor lifting anchors have a distinctive V-shaped head that offers enhanced grip within the concrete matrix. This shape improves load transfer efficiency and reduces the risk of anchor pullout. Suitable for various precast elements, they are valued for their compact design and strong holding capacity under dynamic lifting conditions.

Lifting clutch

The lifting hook is the connection between the lifting anchor and the lifting equipment. It should be easy to install and remove while being secure enough to prevent accidental detachment during lifting.

Rubber Recess Former and Magnetic Recess Former

Rubber recess former: A reusable mold made of durable rubber used to create a clean groove for the lifting anchor in precast concrete, ensuring easy removal and minimizing surface damage.

Magnetic recess Former: A steel mold with a strong magnet that can be quickly attached to the formwork to precisely position grooves in precast concrete, improving efficiency and reducing setup time.

How to Choose the Right Lifting Anchor System

Choosing the right lifting anchor system isn't about choosing the one with the highest load-bearing capacity. Rather, it's about precisely matching the system to project requirements. This ensures project safety, reduces costs, and maximizes profitability.

Load-bearing Requirements and Safety Factors - When evaluating anchors, first determine the maximum deadweight of the component and factor in potential dynamic loads and tilting during installation. A safety factor of at least 3:1 is generally recommended, meaning the anchor's rated load-bearing capacity should be at least three times the maximum load to account for sudden stress fluctuations and ensure safety.

Component Shape and Thickness

Different types of concrete components have varying anchor requirements. Thin plates may require flat-embedded anchors to minimize weakening of the concrete cross-section; thick beams or large components, on the other hand, may require deeper, higher-load anchors to maximize concrete strength.

Concrete Strength

The performance of lifting anchors depends not only on the material and structural design of the anchor itself, but also on the compressive strength of the concrete during installation. Lifting before the concrete strength reaches the designed value may result in anchor pullout or structural damage. Therefore, concrete strength should be rigorously tested before construction to ensure it meets lifting requirements.

Environmental Conditions 

The project environment directly influences the choice of anchor material. In coastal areas, chemical plants, or other highly corrosive environments, it is recommended to use anchors made of stainless steel, hot-dip galvanized, or with special coatings to extend their service life and prevent rust from affecting their load-bearing performance.

International Standards and Certifications 

Choosing lifting anchors that comply with ISO, CE, or other authoritative international standards is not only a guarantee of safety but also a prerequisite for entering international engineering projects. Certified products undergo rigorous quality control processes in design, manufacturing, and testing, resulting in higher reliability.

Supplier Reliability - High-quality suppliers ensure consistent product quality from batch to batch and provide a complete set of technical documentation, including material reports, load-bearing test data, and installation instructions. Additionally, on-time delivery and timely after-sales service are crucial factors in ensuring the smooth progress of the project.

Installation and Safe Operation Tips

Even the best lifting anchor system can fail if improperly installed or used. Here are some key considerations:

Properly position the anchor – Position according to the design drawings to ensure uniform force distribution.

Ensure the anchor is fully embedded to achieve the rated load capacity.

Use the lifting clutch type – Only use a lifting clutch that matches the anchor model.

Control the lifting angle – Avoid excessive stress caused by lifting at high angles.

Pre-lifting inspection – Check for damage or defects.

Common mistakes include using damaged hooks and lifting before concrete reaches the specified strength, both of which pose safety risks.

Why Choose an ISO-Certified Supplier

ISO 9001 quality management certification, in particular, is more than just a certificate; it's a guarantee of consistent quality and standardized production processes.

Working with an ISO-certified lifting anchor system supplier will ensure:

Consistent quality – Consistent product quality from batch to batch. Traceability – Each product has a batch number and quality inspection records.

Risk Reduction – Fewer defects, delays, and unexpected events.

Efficient Communication – Standardized processes mean clear delivery dates and documentation.
