WIRE AND SYNTHETIC ROPE DESTRUCTION TESTING AND WIRE TENSILE TESTING

The quality, integrity and ability of a rope to carry loads safely is a function of the tensile strength of the wire combined with the design and quality of manufacturing employed to produce a wire strand and subsequent rope.

To expand our understanding and ability to test and verify new and existing rope designs Bridon has invested in tensile testing equipment for wire and breaking force test equipment for wire and fibre ropes.

These machines help to establish a rope’s actual breaking strength after manufacture or residual break strength after service. We also undertake post breaking load evaluation after destruction testing to evaluate the mode fracture.

Bridon has three tensile test machines capable of breaking steel ropes up to 800 tonnes and fibre ropes up to 125 tonnes. These machines are equipped with diameter and rope modulus measurement devices.

ROPE TORQUE-TURN TESTING

Different rope constructions exhibit varying degrees of torque and rotation characteristics under load, dependent on rope material and design. To better quantify, understand and then eliminate this phenomenon, Bridon has increased Rope Torsion Testing capability with the addition of a unique 1,500kN Torsion Test Machine.

ROPE BEND FATIGUE TESTING

For many applications the life expectancy and performance of the rope is determined by its ability to endure the fatigue associated with repeated bending over sheaves used in lifting, lowering and conveying equipment.

Our purpose made Bend Fatigue Machines can replicate these dynamic operating conditions including reverse bending to provide more accurate measurement of the deterioration of rope performance.
