Wire Rope Weight Calculation Formula

They have also offered an example of the strength of 3 8 wire rope that has a safe working load of 10 9 kn.

Wire rope weight calculation formula.

M mass in kilograms. To determine the strength the calculation m f g is used where. Wire rope figs 1 2 1x7 7x7 is a parallel lay construction with all filaments the same diameter and tends to be the stiffest of them all. As we all known.

They are also much more resistant to crushing and slightly stiffer. All weight are calculated in kilograms kg. Example maximum safe mass for a 3 8 wire rope. Once you know the diameter of the rope you can apply it to the formula which is swl d 2 x 8.

M f g 1 where. G acceleration of gravity 9 21 m s2 using this equation for the 3 8 wire rope you would calculate the. All diameters are measured in millimetres mm. Wire rope and chain are the important part of the hoist which are closely bound up with the safe work load now let s talk about how to calculate the swl of ropes and chains.

This calculation means the swl of a 1 5 inch diameter rope is 18 tons. Calculating breaking strength safe work load and weight of hawserlaid ropes calculation of approximate breaking strength b s and safe working load s w l for manila rope method of finding the breaking strength b s is to divide the square of the diameter of the rope in millimetres by 200. D represents the diameter of the rope in inches. F force weight in newtons.

F force weight n m mass kg g acceleration of gravity 9 81 m s 2 maximum safe mass for a 3 8 wire rope where the safe load is 10 9 kn can be calculated as. If you re working with a 1 5 inch diameter cable for example then the formula would be swl 1 5 2 x 8 or swl 2 25 x 8. Example of a diameter 24mm manila rope. Diameter in mm squared the weight in kg.
