Nobles Offers a Complete Non-Destructive Testing Service for Wire Rope and Lifting Equipment.

Non-destructive testing (NDT) is a method of inspection of wire ropes that has become part of the mining industry’s standard requirements for over 20 years. Utilising an electronic Magnograph machine, non-destructive testing allows for a full examination of the inside of a wire rope, allowing for early planned replacement, or independent verification that a rope can remain in service.

Regular non-destructive testing provides independent verification that a rope is still safe to remain in service and an independent condition report that can allow for thorough forward planning for replacement at a time that does not interrupt your business demands. We offer this service for ropes in-situ and in service, or during periodic maintenance periods when cleaning and lubrication can be conducted at the same time.

Non-destructive testing of wire ropes involves using a Magnetic Flux Leakage Device passed over the rope to detect corrosion and broken strand of wire; providing a thorough complete inspection of the rope at the time of testing than external examination alone.

Destructive Testing

This method of inspection involves testing an item on a testbed using tensile force until it has reached the Ultimate Break Load, which is recorded and provided on a test certificate.

This type of testing should only be performed in a controlled and approved testing laboratory by a qualified individual to ensure safety and accurate test results.

Nobles testing facilities are NATA accredited which is a further demonstration of our commitment to provide quality. All testing provided by Nobles is conducted by a qualified individual in a controlled environment to ensure the safety of individuals and equipment and to ensure results are compliant with Australian Standards.

Non-Destructive Testing FAQs

Non-destructive testing (NDT) allows for a full internal and external examination of wire ropes without causing damage. This helps identify hidden wear, corrosion, or broken strands early, enabling businesses to plan replacements proactively rather than waiting for a failure. It ensures ongoing safety, reduces unplanned downtime, and extends the lifespan of critical lifting equipment.

Unlike standard visual inspections, which only assess the outer surface of a wire rope, non-destructive testing (NDT) uses a Magnetic Flux Leakage Device to detect internal defects such as corrosion or broken strands. This provides a more comprehensive assessment, ensuring potential issues are identified before they become critical.

Wire ropes should be tested regularly as part of routine maintenance or whenever there is uncertainty about their condition. Many industries, particularly mining, have adopted NDT as a standard requirement to ensure compliance with safety regulations. Testing can be done while the rope is in use or during scheduled maintenance periods when cleaning and lubrication can also be performed.

Destructive testing is used to determine the ultimate break load of lifting equipment by applying tensile force until failure occurs. This method is valuable for assessing the strength and safety margins of new or sample wire ropes but should only be conducted in controlled, accredited testing facilities. Nobles’ NATA-accredited test labs ensure accurate and compliant results for safety-critical applications.
