Unilateral erection anchors serve as specialized lifting inserts for precast concrete, designed for one-sided loading during element erection. They integrate with ring clutches and recess formers, providing stable anchor points that enhance safety and reduce panel stress in construction applications.
Our unilateral erection anchors come in various sizes to suit different safe working loads (SWL) from 2.5 to 26 tons, accommodating diverse precast concrete needs. Made from robust materials such as 20Mn2, Q345D, CM490, or stainless steel, they offer customizable options with surface treatments like electro-galvanized or hot-dip galvanized. Each anchor maintains a safety factor of at least 3, backed by ISO9001 and CE certifications. The table below details dimensions, ensuring precise fits for columns, beams, and wall panels in bulk production runs.

Dive deeper into unilateral erection anchors, essential for precast concrete handling at HULK Metal. These anchors excel in providing secure lift points for edge lifting and rotation, with designs that minimize cosmetic damage to elements. From structure and system components to production steps, this section highlights how our anchors outperform in strength, ease of use, and customization. Bulk buyers gain insights into applications, advantages, and supplier selection tips to ensure optimal project outcomes.
Unilateral erection anchors represent a unique variant among spread anchors, engineered for embedding into precast concrete elements to create dependable lifting points during erection.
These anchors require recess formers to form cavities in the concrete, allowing seamless connections with ring clutches for safe handling.
Unlike standard anchors, their one-sided design suits thin panels where loading occurs from a single direction, reducing stress and preventing cracks.
At HULK Metal, we produce these from premium steels, ensuring they handle shear forces effectively in construction sites. The anchor's split foot and angled end distribute loads evenly, boosting resistance against pull-out. This makes them ideal for tilting operations, where precision matters most.
Our versions come with certifications that guarantee performance under heavy loads, and customizable features align with specific project demands. Bulk purchasers value how these anchors streamline workflows, cutting installation time while enhancing safety. With a focus on durability, they withstand harsh environments better than basic alternatives.
Overall, unilateral erection anchors from our China-based factories empower contractors to erect elements faster and more reliably, backed by our end-to-end support from design to delivery.
These anchors maintain uniform width top to bottom, featuring three holes at the head: the top one links to recess formers and ring clutches, while the lower two secure rebar. Only one side has a notch for rebar clamping, and the forked end angles outward to better transfer stress and heighten pull-out resistance in concrete.
Unilateral Erection Anchor:
The core component, forged from high-strength steel, embeds into precast elements for one-sided lifting. Its design includes holes for rebar and clutches, ensuring stable connections during horizontal-to-vertical shifts in construction.
A reusable mold that creates precise cavities around the anchor head in concrete. It allows easy access for clutches, protects the anchor during casting, and ensures clean recesses for efficient on-site handling.
Attaches to the anchor head for lifting operations. This robust tool locks securely into the recess, enabling cranes to hoist elements safely with minimal slippage, ideal for bulk precast projects.
Complementary hardware that connects clutches to cranes. Made from durable alloys, they provide flexible attachment points, supporting various load angles and enhancing overall system versatility in erection tasks.
CE ISO9001 Certified
Unilateral erection anchors function by embedding into precast concrete during casting, with recess formers creating access pockets. Once cured, ring clutches insert into the recess and lock onto the anchor's head hole. Cranes then attach via lifting hooks, applying force from one side to tilt elements from horizontal to vertical. The anchor's split foot disperses shear loads into the concrete, preventing failures. Rebar through lower holes reinforces stability, while the notched side secures positioning. This setup excels in thin panels, minimizing edge stress.
1. The SWL must meet the intended use.
2. The hole must match the recess former and ring clamp.
3. The anchor must meet the required standards.
4. The unilateral removal anchor must meet the ultimate tensile strength test with a safety factor of 3 times.
Unilateral erection anchors find widespread use in precast concrete construction for lifting and erecting wall panels, beams, columns, and trusses. They shine in projects involving thin-walled elements, such as facades or sandwich panels, where one-sided loading prevents damage during tilting. Ideal for high-rise buildings, bridges, and industrial structures, these anchors support efficient assembly in urban developments. Bulk applications include stadiums and parking garages, where quick, safe handling accelerates timelines.
Compared to standard spread anchors, unilateral erection anchors offer superior adaptability for narrow precast elements, reducing cosmetic cracks during erection. Their one-sided design allows tighter placements, saving material and space. With higher corrosion resistance through galvanizing, they last longer in outdoor settings. Shorter production cycles at HULK Metal mean faster availability for bulk orders, while the 3x safety factor provides greater reliability under dynamic loads. Easier integration with rebar enhances overall structural integrity.
We can develop a comprehensive solution by gaining an in-depth understanding of requirements such as quantity, surface treatment, delivery method and time.
Our procurement team sources premium steels like 20Mn2 or Q345D from trusted suppliers in our supply chain. Each batch undergoes rigorous testing for tensile strength, composition, and defects using advanced instruments to ensure only top-grade materials proceed to production.
Precision cutting machines slice steel plates to exact lengths, followed by hydraulic bending to form the anchor's shape, including split feet and holes. This step guarantees dimensional accuracy for seamless embedding in precast concrete.
After shaping, anchors receive deburring and polishing for smooth edges. Surface options like hot-dip galvanizing apply protective coatings, enhancing rust resistance and uniformity to meet bulk order demands in harsh environments.
Inspectors check every anchor for defects using visual, dimensional, and load-testing methods. Samples endure pulls exceeding three times SWL, ensuring compliance before advancing to packaging for reliable performance.
We customize packaging with protective wraps and crates to prevent damage during transit. Our in-house logistics team coordinates sea, air, or land shipments, offering warehousing to align with your schedules for timely bulk deliveries.
For quality issues, our after-sales team provides prompt resolutions, including replacements or technical guidance. We track orders post-delivery, offering consultation on usage to maximize product value in your projects.
Evaluate the supplier's certifications like CE and ISO9001 to confirm product reliability. Look for those with proven track records in precast concrete, ensuring anchors meet international standards and handle bulk volumes without delays.
Assess production capacity and cycle times to avoid bottlenecks in large orders. Suppliers with advanced factories and integrated supply chains deliver faster, helping you maintain project timelines while keeping costs in check.
Check material quality and testing protocols for consistency. Reliable suppliers source from vetted partners and conduct thorough inspections, reducing risks of failures in critical lifting applications.
Review surface treatment options for corrosion protection suited to your environment. Those offering customizable galvanizing ensure longer anchor life, especially for outdoor or marine precast projects.
