The Dog Bone Lifting Eye is a specialized lifting accessory designed to work with dog bone lifting anchors in precast concrete construction. Its robust structure and precise engineering ensure reliable performance in heavy-duty lifting tasks. Manufactured from alloy steel and tested with a 5x safety factor, it delivers both strength and durability. With CE and ISO 9001 certification, it meets international safety standards, making it a trusted choice for bulk projects.
A Dog Bone Lifting Eye is a critical lifting component used for handling precast concrete elements safely and efficiently. Designed to connect securely with dog bone anchors, it creates a reliable lifting point for cranes and lifting hooks. Its unique structure ensures stability and reduces the risk of failure during heavy lifting operations.
This lifting eye is manufactured from high-performance alloy steel, offering excellent tensile strength and long service life under demanding construction environments. The spherical head design fits perfectly into the anchor recess, while the welded ring and bar provide secure attachment points for lifting hooks. With strict adherence to CE and ISO 9001 standards, every unit is thoroughly tested to guarantee consistent quality and safety.
The Dog Bone Lifting Eye is widely applied in precast concrete production, enabling contractors to lift and position heavy panels, beams, and structural elements with greater efficiency.
Precision-cast from high-performance alloy steel, the head is spherical with a circular cross section on both sides. A central hole allows the ring to pass through, while a cavity accommodates the spherical head of the dog bone anchor. The head also includes an ear to connect the lifting eye securely to the anchor.
The ring is heat-bent from alloy steel, passed through the head’s hole, and welded firmly to the bar to ensure strong load-bearing capacity.
The bar is cut from alloy steel with one end reserved for welding the ring. The opposite end is shaped with a loop for reliable attachment to lifting hooks.
The lifting eye connects to the dog bone anchor to form a secure lifting system. Made from alloy steel, it ensures strength, safety, and repeated usability in precast concrete lifting operations.
The recess former creates the precise cavity required for positioning the dog bone anchor in concrete elements, ensuring accurate installation and allowing the lifting eye to fit seamlessly into the anchor system.
These anchors are embedded in concrete and act as the main load-bearing points for lifting. When paired with lifting eyes, they provide a reliable connection for handling precast components with different load capacities.
Lifting hooks attach to the bar of the lifting eye and connect with cranes. They enable safe, controlled handling of precast concrete panels, ensuring stability and efficiency during transportation and installation.
CE ISO9001 Certified
The Dog Bone Lifting Eye works by securely engaging with the embedded dog bone anchor. The spherical head of the anchor fits into the cavity of the lifting eye head, while the bar and ring provide the connection point for lifting hooks. This system distributes load evenly, minimizing stress concentration and ensuring safe lifting of heavy precast concrete elements.
SWL must meet usage requirements.
Load Group must match the Dog Bone Lifting Anchors.
Must comply with standards.
Dog Bone Lifting Eye must meet the ultimate tensile strength test with a safety factor of 5 times.
The Dog Bone Lifting Eye is widely applied in the lifting and handling of precast concrete components, including wall panels, beams, staircases, and floor slabs. It provides reliable connection points for cranes and lifting systems, enabling safe transportation and precise installation on construction sites. Its robust design makes it suitable for both small-scale and large-scale precast projects.
The Dog Bone Lifting Eye offers multiple advantages such as high strength, long service life, and strict compliance with international standards. Its efficient design ensures easy connection with anchors and hooks, reducing labor time. A shorter production cycle and faster delivery enhance supply reliability, while comprehensive after-sales support ensures long-term value for bulk buyers.
We carefully assess requirements such as order quantity, surface treatment, delivery timeline, and technical specifications. By fully understanding each project’s needs, we develop tailored production solutions that ensure optimal performance, cost-effectiveness, and timely delivery for every bulk order.
Raw Material Purchasing & Testing:
High-quality alloy steels such as Q345D, Q355D, or customized grades are sourced from trusted suppliers. Each batch undergoes strict chemical composition and mechanical property testing to ensure the material’s reliability and compliance with CE and ISO standards before production begins.
The head is produced through precision casting to achieve a smooth surface and accurate dimensions. Advanced casting technology ensures the head’s spherical cavity fits perfectly with the anchor, providing reliable strength and consistency for repeated lifting operations.
High-performance alloy bars are cut with precision machinery to achieve accurate sizes. Each cut piece is inspected for straightness and dimensional accuracy, ensuring a stable foundation for the subsequent welding and assembly processes.
Rings are heat-bent with controlled processes to maintain uniform shape and strength. Careful bending prevents material fatigue or cracks, ensuring each ring has the durability and performance needed for demanding lifting operations in precast concrete handling.
Quality Inspection Every Parts:
Each head, bar, and ring undergoes dimensional and mechanical inspections before assembly. Strict checks guarantee that every component meets required standards, reducing the risk of failure and ensuring stable lifting performance under heavy loads.
Skilled technicians weld the ring to the bar and assemble all components into the lifting eye. Precision welding techniques ensure strong joints that withstand heavy loads, creating a reliable and safe product for demanding lifting applications.
The assembled lifting eye is finished and electro-galvanized to resist corrosion. Surface treatments improve durability, extend service life, and maintain the product’s appearance, making it suitable for long-term use in harsh construction environments.
After surface treatment, each lifting eye is inspected again for dimensions, load capacity, and finishing quality. Final testing ensures that every unit leaving the factory meets CE, ISO, and customer-specific requirements for safe usage.
