FAQs
What type of chain is this coupling link designed for?
This coupling link is specifically designed for 10mm Grade 80 chain.
What does the 4:1 safety factor mean?
A 4:1 safety factor means the link's ultimate breaking strength is at least four times its Safe Working Load (SWL). For this link, the SWL is 3.15 tons, meaning its breaking strength is approximately 12.6 tons.
Can this link be used with lower-grade chain?
No, it is essential to use this link only with compatible Grade 80 chain and fittings to ensure safety and maintain compliance with standards.
What is the Safe Working Load (SWL) of this link?
The Safe Working Load (SWL) for this 10mm Grade 80 half coupling link is 3.15 tons.
How should I clean the coupling link?
Clean the link with a damp cloth. Avoid using abrasive materials or harsh chemicals.
What standards does this coupling link conform to?
This coupling link conforms to BS EN 1677 standards.
What does the yellow finish indicate?
The yellow finish is a color-coding system for visibility and easy identification of Grade 80 lifting components.
Troubleshooting
Coupling mechanism is stiff or difficult to engage.
Ensure the chain and the receiving fitting are clean and free of debris. Check for any minor deformation on the link or fitting. Lubrication may be applied sparingly if recommended by the fitting manufacturer, ensuring it does not compromise the load-bearing surface.
Link appears discolored or shows minor surface rust.
Surface rust can often be removed with a soft brush and mild cleaning agent. Significant discoloration or deep corrosion may indicate material degradation and the link should be removed from service.
Concerns about the load rating being exceeded.
Never exceed the Safe Working Load (SWL) of 3.15 tons for this link. Always consider the SWL of all components in the lifting assembly and use the lowest SWL as the maximum for the entire assembly.
Pros and Cons
Pros
High strength and durability due to Grade 80 material.
Certified to BS EN 1677 standards for safety assurance.
Clear 4:1 safety factor provides confidence in load handling.
Yellow finish enhances visibility in work environments.
Designed for secure connections with compatible locking fittings.
Cons
Only compatible with 10mm chain.
Requires specific locking fittings for full functionality.
Not suitable for use with lower-grade chain or components.
Requires proper inspection and maintenance to ensure ongoing safety.
Setup, Compatibility & Care
Setup:
Ensure the 10mm chain is clean and free from damage.
Align the half coupling link with the end of the chain intended for connection.
Securely engage the coupling mechanism according to the manufacturer's instructions for the specific locking fitting (e.g., coupling self-locking hook) being used.
Compatibility:
This coupling link is specifically designed for 10mm Grade 80 chain. Using it with other chain sizes or grades may compromise safety and is not recommended.
It is intended for use with other Grade 80 lifting gear components that feature a compatible half coupling lock.
Care:
Regular Inspection: Visually inspect the link before each use for any signs of wear, deformation, cracks, or corrosion. Pay close attention to the locking mechanism.
Cleaning: Clean with a damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the material or finish.
Storage: Store in a dry, protected environment when not in use to prevent rust and damage.
Load Limits: Always adhere to the stated Safe Working Load (SWL) of 3.15 tons and the overall load limits of the lifting assembly.
