Tensile strength of wires and breaking force of rope

The mechanical properties, which are important when lifting a load under normal conditions, are the tensile strength of the rope and the ductility of the wires. Ductility is usually measured by standard engineering tests of tensile strength, torsion, elongation and bending. The strength of the rope, when applied to the factor of safety for the duty, determines the working load.

• Do they have an active program to determine the strength and ductility of the wires?

• Is it a minimum or actual breaking strength on the certificates?


BRIDON has an active program to verify the properties of its wires. Testing audits are continuously performed on all products. Bridon's design philosophy takes into account the need to verify whatever minimum breaking force is being specified.

The "Powercheck" symbol means that BRIDON has carried out a destruction test on a sample of rope from production length.
