Kuplex G8 Chain CN1133

The Kuplex G8 Chain CN1133 is a high-performance lifting chain engineered for reliability, durability, and compliance with stringent safety standards. As part of the Crosby Kuplex product range, this Grade 8 chain is purpose-built for use in chain sling assemblies and lifting systems across a wide variety of industrial sectors. It offers a dependable solution for lifting tasks that demand strength, flexibility, and assurance of performance in line with recognised industry specifications.

Used in conjunction with compatible Kuplex components—such as hooks, connectors, and shortening clutches—the Kuplex G8 Chain CN1133 forms the backbone of robust chain sling configurations. Whether applied in general construction, offshore rigging, plant maintenance, or manufacturing operations, this chain delivers consistent results in environments where safety and performance are critical.

Key Features and Benefits

Grade 8 Classification:
Manufactured as a Grade 8 chain, the Kuplex G8 Chain CN1133 offers enhanced strength and wear resistance compared to lower-grade chains. Grade 8 chains are designed for lifting applications and are heat-treated and tested to perform in line with international lifting requirements. This classification makes them suitable for a wide range of medium to heavy-duty lifting applications.

Compliance with BS EN 818-4:1997:
The Kuplex G8 Chain CN1133 fully complies with BS EN 818-4:1997, the British and European standard for chain slings made of short link chain for lifting purposes. This ensures that each length of chain is manufactured and tested to meet strict guidelines around mechanical properties, proof loading, working load limits (WLL), and traceability.

4:1 Safety Factor:
With a built-in safety factor of 4:1, the chain is designed to withstand forces significantly beyond its rated working load limit. This margin offers protection against sudden or unexpected loading scenarios, such as shock loading or uneven weight distribution, giving users peace of mind in demanding lifting operations.

Reliable Performance in Endless Sling Configurations:
The Kuplex G8 Chain CN1133 can be used in endless sling arrangements, where the chain forms a continuous loop. In these applications, the circumference of the sling is calculated as twice the Effective Working Length (EWL). This setup is beneficial for lifting round or irregular loads and allows for efficient rotation of contact points to reduce wear and extend chain life.

High Compatibility:
The CN1133 chain is compatible with a full range of Crosby Kuplex components, including master links, hooks, and clutches. This allows for straightforward assembly into single-leg, two-leg, three-leg, or four-leg slings, providing flexibility for the end user. Chains can be easily customised to meet specific lift requirements, whether in fixed or adjustable configurations.

Durable Construction for Industrial Use:
The chain’s robust construction and precision engineering make it well-suited for industrial use in sectors such as oil and gas, utilities, heavy fabrication, construction, logistics, and marine environments. Its high resistance to abrasion and fatigue ensures a long service life, even under repetitive or challenging lifting conditions.

Traceability and Identification:
Each Kuplex G8 Chain CN1133 length includes identification markings in accordance with the EN standard. This ensures complete traceability throughout the product’s lifecycle—from manufacture to inspection and maintenance. Clear markings help simplify in-field inspections and compliance audits, ensuring that only certified equipment remains in operation.

Typical Applications

The Kuplex G8 Chain CN1133 is designed for use in lifting applications where reliability, safety, and compliance are non-negotiable. Common industries and scenarios include:

• Crane lifting and rigging

• Heavy machinery movement

• Offshore platform operations

• Structural steel installation

• Equipment maintenance

• Utility and infrastructure work

Its versatility and conformity to high safety standards make it an ideal choice for professional rigging teams and lifting engineers who require equipment that performs under pressure.

The Kuplex G8 Chain CN1133 is a trusted chain solution for modern lifting applications. With its Grade 8 classification, BS EN 818-4:1997 compliance, and high safety factor, it provides a strong foundation for chain sling assemblies in industrial and construction environments. Whether used on its own or integrated into multi-leg sling configurations, this chain delivers the performance and reliability expected from Crosby Kuplex lifting equipment.
