Strength Of Wire Rope Formula

D is the diameter of the rope in millimeter the safe working load maybe taken as one sixth 1 6 of.

Strength of wire rope formula.

This three layered design increases the density of our wire rope and reduces its risk of fraying or breaking allowing for superior tensile strength and durability compared to other wires cables and steel chains. It is a system for significantly increasing the strength and flexibility of steel wire and. The breaking stress of a flexible steel wire rope is given approximate by the following formula. A rope s minimum tensile strength is calculated in the same way but it takes the average strength rating and reduces it by 20.

Wire rope is also known by many other names such as. Diameter in mm squared the weight in kg. Wire multi strand wire flexible wire cable cord steelcord etc. All diameters are measured in millimetres mm.

But it is essentially a collection of small filaments wound around each other in a manner that largely retains its shape when bent crushed and or tensioned. Rope diameter minimum breaking strength safe load weight in mm lb f kn lb f kn lb m ft kg m 1 4. Wire rope safe working load the term safe working load swl of wire rope means the load that can be applied and still obtain the most efficient service and also prolong the life of the rope. 6 x 24 20d2 tons 500.

The formula for computing the swl of a wire rope is the diameter of the rope squared multiplied by 8 d x d x 8 swl in tons. As we all known. 6 x 12 15d2 tons 500. The wire rope is.

Charles missouri 63303 866 852 9714. Industrial wire rope 7390 harrison avenue cincinnati ohio 45247 888 345 0919. 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. 6 x37 21d2 tons 500.

This number is often used instead. 2086 exchange drive st.
