S-281
Web Sling Shackle
|
 
|
 |
 Incorporates same ear spread and pin dimensions as conventional Crosby
Shackles. Allows easy connection to pad eyes, eye bolts, and lifting lugs. Increased radius of bow gives wider sling
bearing surface resulting in an increased area for load distribution, thus:
- Increasing Synthetic Sling efficiency by at least 15% 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.
All Alloy Construction
Design Factor of 5 to 1.
Each shackle has a Product Identification
Code (PIC) for material traceability along with a Working Load Limit and the name Crosby
forged into it.
Look for the Red
Pin® ... The mark
of genuine Crosby Quality. |
