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.

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.
