Common Concerns Answered
Is the self-locking pin difficult to operate?
While some users note the self-locking pin can be slightly stiffer initially compared to standard screw pins, this is a trade-off for enhanced security. The mechanism is designed for reliable engagement and is simple to operate with a push and twist motion once accustomed.
Why is this shackle more expensive than basic screw pin types?
The higher price point reflects the advanced self-locking mechanism, which provides superior vibration resistance and security, preventing accidental loosening. It is also forged from high-grade 316L stainless steel, offering extended durability and corrosion resistance in demanding marine environments.
How does the self-locking mechanism ensure security?
The self-locking pin incorporates a unique indent system that engages positively, preventing rotation and loosening caused by constant vibration inherent in marine applications. This ensures your rigging remains secure when it matters most.
Frequently Asked Questions
What is the working load limit (WLL) for the Wichard Self-Locking Shackle?
For industrial applications, the Working Load Limit (WLL) for this 8mm shackle is 1190 lb (540 kg). For nautical applications, the relevant rating is the Working Load (WL) of 1780 lb (810 kg).
What is the difference between Working Load (WL) and Working Load Limit (WLL) for this shackle?
Working Load (WL) is typically used for nautical applications and represents the maximum load the shackle can safely handle in marine environments. Working Load Limit (WLL) is a term more commonly used in industrial settings and often has a lower safety factor applied than WL.
What type of stainless steel is used in the Wichard Self-Locking Shackle?
This Wichard shackle is forged from Grade 316L stainless steel, renowned for its exceptional resistance to corrosion, particularly in saline and humid marine environments, ensuring longevity and reliability.
What are the dimensions of the Wichard Self-Locking Large Opening Shackle?
The shackle has a pin diameter of 8mm (5/16"). Key external dimensions include an overall length (G) of 3 1/32" (77mm) and an internal width (F) of 3 1/32" (77mm).
Is this shackle suitable for lifting applications?
While this shackle possesses high breaking and working loads, it is primarily designed and recommended for rigging and attachment in marine applications where vibration is a concern. For dedicated lifting operations, always consult specific lifting equipment regulations and certifications.
