The LQ-720 European Type Master Link with Flat is a high-performance top connector specifically designed for critical lifting, load handling, and rigging operations in demanding industrial applications and offshore platforms.
1. Construction and Design Features
- Integrated Flat Section: The master link body features an engineered flat section meticulously integrated into its structure. This “flat” design is essential to facilitate the quick and direct assembly of connecting links (such as coupling links), preventing spatial interference during rigging composition.
- High-Visibility Protective Finish: The component features a robust, brightly colored surface coating that protects the steel against oxidation and aggressive wear in challenging environmental conditions while ensuring easy visual inspection on the field.
2. Rigorous Safety Criteria and Testing
The structural integrity of Loquen master links is certified through stringent mechanical testing standards:
- Safety Factor: 4:1.
- Ultimate Load: Engineered to withstand an ultimate breaking force equivalent to 4 times the Working Load Limit (WLL) before structural failure.
- Angled WLL Certification: Operational load ratings (WLL) are strictly calculated and qualified based on sling configurations operating at standard angles from 0° to 45°.
3. Complete Range of Models and Capacities (LQ-720 Series)
