How to calculate Sling capacity and Sling angle calculation formula
Sling WLL at specified angle = Sling WLL x No. of legs x Sling angle factor

Example:- Sling (WLL) = 2000kg
Sling angle = 60 degree
No. of legs = 2
Sling capacity (WLL) at a 60-degree angle?
Now, put these value in the above formula
Sling WLL at a 60-degree angle = 2000kg x 2 x 60 degree
= 2000kg x 2 x 0.866
= 3464kg
Note:- if we consider a 60-degree angle for sling then the reduction factor is 0.866 as per the chart.

Consider, we don’t know the sling angle then how we can calculate the sling angle factor?
Sling angle factor = H/L ( H – Height & L- Length)
= 1/1.2
= 0.83
