The Ring Clutch Lifting Device section provides a complete technical and practical overview of our lifting solution. It covers product composition, surface treatment options, manufacturing process, usage instructions, safety precautions, and applications for various precast concrete elements. Bulk buyers and project engineers can understand how to select, install, and operate the lifting ring clutch safely. This detailed guidance highlights HULK Metal’s technical expertise, quality assurance, and support for reliable, high-performance lifting operations.
A Ring Clutch Lifting Device is a specialized lifting accessory used in precast concrete handling systems. It connects lifting equipment to embedded spread anchors, allowing safe lifting, rotation, and positioning of heavy concrete elements. Compared with fixed lifting points, a lifting ring clutch can automatically align with the load direction, reducing stress concentration and minimizing the risk of damage during hoisting.
Manufactured from high-strength structural steel or alloy steel, the ring clutch is designed to withstand repeated lifting cycles on construction sites. It is widely used in precast walls, beams, columns, stairs, and infrastructure components where controlled lifting and precise positioning are required. For large-scale construction projects, a reliable Ring Clutch Lifting Device ensures higher efficiency, improved safety, and consistent performance throughout the lifting process.
The latch is a critical safety component that locks the ring clutch onto the spread anchor. It is designed to open smoothly for installation and close securely under load, preventing accidental disengagement during lifting operations.
The ring is the main load-bearing element, allowing the lifting force to be transferred evenly from the crane hook to the anchor. Its rounded shape enables rotation and self-alignment with the lifting direction.
The bar connects the ring to the internal locking structure and supports stable movement during opening and closing of the latch.
During assembly, the latch is inserted into the internal cavity of the ring and secured by riveting to prevent it from sliding out during operation. The ring itself is formed from hot-bent steel bar and welded firmly to the handle structure. This manufacturing method ensures structural integrity, stable load transmission, and long-term durability under repeated lifting conditions on construction sites.
HULK Metal supplies Ring Clutch Lifting Devices with electro-galvanized and hot-dip galvanized surface treatments. Electro-galvanizing provides a clean appearance and effective corrosion protection for standard construction environments, while hot-dip galvanizing offers thicker zinc coating for harsher outdoor conditions. Additional passivation treatment can be applied to further improve wear resistance and extend service life during frequent lifting operations.
Ring Clutch Lifting Devices are produced through controlled material selection, forging or forming, precision machining, welding, and surface treatment. Each unit undergoes dimensional inspection, functional testing, and safety factor verification before delivery. This standardized production flow ensures consistent load capacity, stable performance, and reliable compatibility with spread anchors used in precast concrete systems.
When using a Ring Clutch Lifting Device, the operator first opens the latch to expose the slot on the ring. The slot is then positioned onto the head of the spread anchor embedded in the concrete element. After positioning, the latch is released, allowing it to pass through the anchor hole and be fully pushed into place. Once secured, the ring clutch automatically aligns with the lifting direction as load is applied. This process ensures stable force transmission, reduces improper loading, and improves safety during lifting and positioning of precast concrete components.
1. Do not attempt any repairs if any part of the Ring Clutch Lifting Device is damaged; replace it directly.
2. Ensure it maintains the correct force direction, as incorrect force direction will damage the Precast Concrete Elements.
3. Ensure the SWL and Spread Anchor are compatible; otherwise, it will not function properly.
4. Ensure the Ring Clutch Lifting Device meets CE certification requirements and has a 5-times safety factory inspection certificate.
Ring Clutch Lifting Devices are widely used in precast concrete handling for safe and controlled lifting. Typical precast elements include:
Precast wall panels
Precast beams
Precast columns
Precast stairs
Precast slabs
When using a Ring Clutch Lifting Device, ensure it is fully engaged with the correct spread anchor and properly aligned with the lifting direction. The SWL must match the component weight, and installation errors or angled loading can cause anchor damage, unstable lifting, or safety risks on-site.
