Ratings below are for use with chain slings fabricated in accordance with ASME B30.9.
- Alloy Steel — Quenched and Tempered.
- Individually Proof Tested with certification.
- Proof Tested with fixture sized to prevent localized point loading per ASTM A952.
- Crosby A-342 products meet or exceed all requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, Crosby products meet other critical performance requirements including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
- Sizes from 1/2” to 2” are drop forged and 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.
- Incorporates patented QUIC-CHECK® deformation indicators.
