General formulas for calculating SWL in direct lift (no angle or reeve factors):sports74.ru

SWL of FSWR : SWL (kg) = D x D (mm) x 8

If load is known, minimum size Diameter of FSWR: D (mm) = √Load (kg) ÷ 8

SWL of Grade 80 Chain: SWL (kg) = D x D (mm) x 80 x 0.4

If load is known, minimum Diameter of G80 Chain: D (mm) = √L (kg) ÷ 0.4 ÷ 80

Once angle or/and reeve factors are present, formula for maximum load that can be lifted is:

Max load = SWL (of sling) x angle factor x reeve factor

If load is known, to calculate minimum capacity sling use formula:

SWL = weight ÷ angle factor ÷ reeve factor
