Wire Rope Weight Calculation Formula

As we all known.

Wire rope weight calculation formula.

Example of a diameter 24mm manila rope. All diameters are measured in millimetres mm. D represents the diameter of the rope in inches. They have also offered an example of the strength of 3 8 wire rope that has a safe working load of 10 9 kn.

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. This calculation means the swl of a 1 5 inch diameter rope is 18 tons. M mass in kilograms. F force weight in newtons.

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. 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. 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. Example maximum safe mass for a 3 8 wire rope.

To determine the strength the calculation m f g is used where. Warrington fig 1 is a parallel lay construction with an outer layer. M f g 1 where. All weight are calculated in kilograms kg.

The relationship between mass and force weight can be expressed as. Wire rope construction iwrc wire ropes are slightly 7 stronger that those with fabric or polymer fillers. Diameter in mm squared the weight in kg. 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.
