WebSling is safely rated for both a straight 90° pull and a double-branch sling at 30°. Fig. 3 shows an arrangement where a single chain sling is wrapped around the workpiece and used in a choke hitch similar to double branch sling. In a tight choke hitch, the branch angles can be too low and the resulting tension load Web2) Determine the Share of the Load (SOL) for the individual sling legs: Divide the load weight by the number of sling legs. Load weight ÷ number of legs = Share of the Load (SOL) Example: 12,000 lbs ÷ 3 legs = 4,000 …
