A Ring Clutch is a specialized lifting device used in conjunction with Spread Anchors to handle precast concrete elements. It is designed to withstand heavy loads while ensuring safe and controlled lifting. The Ring Clutch works by connecting securely to the Spread Anchor and transferring load through its latch, ring, and handle assembly. Its robust structure makes it suitable for repeated use in construction projects.
At HULK Metal, our Ring Clutch are manufactured with advanced processes including precision casting, hot forging, and laser cutting. Each unit undergoes strict inspections to meet CE and ISO 9001 requirements. The five times safety factor ensures reliability even in challenging lifting operations. Combined with surface treatments for corrosion resistance, our Ring Clutch maintain excellent durability and performance. They provide contractors and builders with a dependable lifting system solution for precast concrete handling.
Produced by precision casting, the ring includes a central cavity for securing the latch. It carries a clear Load Group marking to ensure traceability.
Manufactured by hot forging, the latch has a hole for rope connection, enabling easy disassembly after lifting. A pin secures it in the ring cavity.
Crafted from high-performance steel plate, laser cut, and hot-bent. Connected to the ring with high-strength argon arc welding for long-lasting durability.
The hot-bent steel rod passes through the ring and is permanently fixed by argon arc welding to achieve secure integration.
Zinc electroplating with an average thickness of 5μm provides corrosion protection and extended service life.
Open the latch, align the ring with the Spread Anchor gap, secure the connection, and lock the latch. Ensure correct load direction to avoid concrete damage.
The Ring Clutch is the main component designed to connect with Spread Anchors for safe lifting. Its forged, cast, and welded structure ensures strength, durability, and secure handling in demanding precast concrete applications across construction projects worldwide.
The Recess Former is used to create an accurate recess in concrete, ensuring the Spread Anchor can be properly seated. It works together with the Ring Clutch system to guarantee stability, safety, and smooth lifting performance in construction environments.
Spread Anchors provide a reliable load-bearing point within the precast concrete element. When combined with the Ring Clutch, they form a secure lifting system that guarantees stability, improved handling efficiency, and consistent safety for heavy-duty concrete lifting operations.
Lifting Hooks are used in conjunction with Ring Clutch and other lifting gear to provide an extended lifting solution. They help transfer loads efficiently, improve operational flexibility, and allow safe, controlled handling of precast concrete elements during installation.
CE ISO9001 Certified
The Ring Clutch operates by engaging its latch into the Spread Anchor cavity. Once secured, it transfers the lifting load through the forged latch and cast ring, evenly distributing force. The handle provides operational convenience, ensuring stability and safety during lifting.
SWL must meet usage requirements.
