The LQ-710 Type Bow Shackles with Safety Bolt are high-performance connectors specifically designed for critical lifting, load handling, and rigging operations in demanding industrial applications and offshore platforms.
1. Construction and Protection Features
- Anti-Corrosion Surface Treatment: The shackle body is finished with hot-dip galvanizing, while the fastening pin receives a yellow electrostatic powder coating, providing excellent resistance to oxidation and wear in highly aggressive saline and marine environments.
- Double-Locking Design: These bow-type shackles are equipped with a safety bolt and cotter pin. This mechanism is essential to prevent accidental loosening or unscrewing of the pin due to vibrations and dynamic oscillations during load handling operations.
2. Rigorous Safety Criteria and Testing
The structural robustness of Loquen shackles is certified through stringent mechanical testing:
- Safety Factor: 6:1.
- Proof Load: Tested at 2 times the Working Load Limit (WLL).
- Breaking Load: Withstands a force equivalent to 6 times the Working Load Limit (WLL) before failure.
3. Complete Range of Models and Capacities (LQ-710 Series)
The range consists of 19 nominal size variations, covering applications from small industrial operations to heavy-duty lifting in the hundreds-of-tonnes range:
