How is SWL of D shackle calculated?

Formula: SWL (kg) = D2(mm) x 8 For example: Rope dia (D) = 12 mm SWL (kg) = D2 (mm) x 8 = D (mm) x D (mm) x 8 = 12 x 12 x 8 = 1152 kg SWL (t) = 1.15 tonnes The above equation can be reversed to calculate the diameter (D) in millimetres of FSWR needed to lift a given load.

EXAMPLE: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended.

How is SWL calculated?

Once you know the diameter of the rope, you can apply it to the formula, which is SWL = D2 x 8. D represents the diameter of the rope in inches. If you’re working with a 1.5-inch diameter cable, for example, then the formula would be SWL = 1.52 x 8 or SWL = 2.25 x 8.
