Crosby Screw Pin Sling Shackles.

S253 drawing

All Alloy Construction Shackles available in size 3-1/4 to 50 tons. Bolt (Pin) has a larger diameter that provides better load distribution. Each shackle has a Product Identification Code (PIC) for material traceability along with a Working Load Limit and the name Crosby forged into it.

  • Design factor of 5 to 1.
  • Increased radius of bow gives wider sling bearing surface resulting in an increased area for load distribution, thus:
    • Increasing synthetic sling efficiency as compared to standard anchor and chain shackle bows and conventional eye hooks. This allows 100% of the slings rated Working Load Limit to be achieved.
    • Allowing better load distribution on internal fibers.
  • Crosby products meet or exceed all the requirements of ASME B30.26 including identification, ductility, design factor, proof load and temperature requirements. Importantly, Crosby products meet other critical performance requirements inluding fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
  • Shackles available in both a screw pin and bolt, nut and cotter pin configuration.
  • Look for the Red Pin ... The mark of genuine Crosby quality
