Wide Body Design Advantages:

The wide body design provides critical advantages for complex rigging scenarios, particularly at this maximum capacity level. The extra interior space allows for easy attachment of top and bottom fittings, accommodates shackles and other hardware without binding, and provides clearance for multiple connection points. This versatility makes connecting links essential for creating custom rigging assemblies, extending chain lengths, and connecting chain to other rigging components in heavy-duty applications.

Mechanical Lock Security:

The center pin mechanical lock provides secure closure that prevents accidental opening under load or during handling. Unlike simple slip-fit designs, the mechanical lock ensures the link remains closed throughout the rigging operation, providing enhanced safety and reliability in professional lifting applications—critical at this maximum capacity level.

DIN EN 1677-1 Certification:

Testing according to DIN EN 1677-1 European standards ensures this connecting link meets rigorous quality and performance requirements. This certification provides assurance of consistent manufacturing quality, proper material specifications, and reliable performance in professional rigging applications.

Applications:

Ideal for maximum capacity professional rigging operations, heavy-duty chain-to-chain connections, chain length extensions, top and bottom fitting attachments, shackling applications, chain-to-hardware connections, and industrial lifting where secure, versatile connecting links with maximum capacity are required. Perfect for heavy construction, steel erection, bridge construction, shipbuilding, offshore operations, heavy manufacturing, and any application requiring reliable chain connections with accommodation for additional hardware at maximum capacity levels. Commonly used to connect heavy chain sling legs, extend chain lengths, attach chains to large shackles or hooks, and create custom rigging configurations for extreme loads.

Safety Note: Always inspect connecting links before use for wear, deformation, or damage to the mechanical lock. Ensure the center pin is properly engaged and locked. Never exceed the working load limit. Use only with Grade 80 chain rated for equivalent loads. Regular inspection and maintenance are critical at this maximum capacity level.
