Common Concerns Answered
What is the difference between Working Load (WL) and Working Load Limit (WLL) for this Wichard shackle?
The nautical Working Load (WL) for this shackle is 19400 lb (8800 kg), which is the maximum load it is designed for during normal marine operations. The industrial Working Load Limit (WLL) is 12340 lb (5600 kg), a safety factor typically used in industrial contexts and should not be confused with the nautical working load.
Can this Wichard HR Bow Shackle be used for mooring applications?
No, this shackle is explicitly not suitable for mooring applications. Its design and load ratings are intended for dynamic rigging and connection purposes, not for static mooring connections.
Why is the WLL for industrial use lower than the nautical WL?
The WLL for industrial applications often incorporates different safety factors and standards compared to nautical usage. It's crucial to adhere to the specified nautical working load for marine applications to ensure safety and longevity.
Frequently Asked Questions
What are the primary applications for the Wichard HR Bow Shackle - 20mm?
