Crosby A-342 Alloy Master Links

SKU: GRRR315 Category: Master Links

Product details

Alloy steel — Quenched & Tempered.
Individually Proof Tested to values shown, with certification.
Proof Tested with special fixtures sized to prevent localized point loading.
Forgings have a Product Identification Code (PIC) for material traceability, along with the size, the name Crosby and USA in raised lettering.
Selected sizes designated with “W” in the size column have enlarged inside dimensions to allow additional room for sling hardware and crane hook.
Crosby 7/8” to 2” A-342 master links are type approved to DNV-ST-E271-2.7-1 Offshore Containers. These Crosby master links are 100% proof tested, MPI and impact tested. The tests are conducted and 3.1 test certification is available upon request. Refer to the Crosby COLD TUFF® master links that meet the additional requirements of DNV rules for certification of lifting appliances - Loose Gear.
Incorporates patented QUIC-CHECK® deformation indicators.
Fatigue rated to 20,000 cycles at 1-1/2 times the Working Load Limit.
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.

5:1 Design Factor. 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. Applications with wire rope and synthetic sling generally require a design factor of 5.

Proof Test Load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9.

†Offshore Container Master Links Proof Tested to 2.5 times the Working Load Limit with 70 percent fixtures.

Chain slings require that the Minimum Ultimate Load be 4 times the Working Load Limit. Refer to applications & warnings to determine products actual Ultimate Load. Proof Test Load equals or exceeds the requirement of ASTM A952(8.1) and ASME B30.9-1.4 for the chain size and number of legs.
