Crosby 'A344' Welded Master Links Assembly, WLL Range from 1600kg to 24.5 tonnes

The ultimate Load is 5 times the Working Load Limit.  Applications with wire rope and synthetic sling generally require a design factor of 5.  Based on single leg sling (in-line load), or resultant load on multiple legs with an included angle less than or equal to 120 degrees. ** Proof Test Load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9. For use with chain slings.

• Alloy Steel - Quenched and Tempered.
• Individually Proof Tested to values shown, with certification.
• Proof Tested with 70% inside width special fixtures sized to prevent localized point loading per EN 1677-4.
• Each link has a Product Identification Code (PIC) for material traceability, along with the size and the name Crosby® or “CG”.
• Large inside width and length to allow additional room for sling hardware and crane hook.
• Engineered Flat for use with S-1325A coupler link.
• Meets or exceeds all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, these links meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
• Master links are type approved to DNV Certification Notes 2.7-1- Offshore Containers. These Crosby master links are 100% proof tested and impact tested.The tests are conducted by Crosby and 3.1 test certification is available upon request.
• 12mm through 32mm have Engineered Flat.
