Our Technology

Compared to our competitors’ equipment, our wire rope testers offer superior inspection accuracy and signal fidelity. This means:

Not all electromagnetic wire rope testers are created equal. Ours are more accurate, with higher resolution and superior signal fidelity, and they use our patent-pending technology to detect and accurately measure internal rope deterioration such as internal clusters of broken wires, interstrand nicking, fretting, and corrosion pitting. Claims are one thing, but the best way to understand our technology is to compare our inspection equipment with that of our competitors. contact us.

•  For example, we offer the only available wire rope NDE equipment that allows a reliable detection and quantitative characterization of internal broken wires, single and in clusters, and corrosion pitting. (Internal broken wires and broken wire clusters typically occur in multistrand non-rotating and IWRC ropes that are used, for example, as crane ropes.)

•  This important capability has been verified by independent Round Robin tests as reported by Martin Dohm. These independent Round Robin tests compare the performance of most competing rope testers for the detection and quantitative characterization of internal clusters of broken wires. Particularly, the discussion on pp. 36 – 59 is quite interesting. It shows that, among all commercially available instruments that participated in these Round Robin tests, only ours were able to reliably estimate the number of internal broken wires (single and in clusters (see pp. 46 – 51).

•  This unique feature is now integrated in our NDT_CARE™ (Computer-Aided Rope Evaluation) software, and it can be routinely used for electromagnetic wire rope inspections. For details please contact us. As an aside, we consider this method the first significant innovation in the discipline of wire rope NDE since the 1980s.

•  Our instruments use our proprietary Magnetic Flux Compression/Decompression technology that offers superior inspection accuracy(resolution), and a signal fidelity that is better by an order of magnitude than that of any competing wire rope tester. This makes our test results accurate and, therefore, greatly facilitates their interpretation by the inspector.

•  Our exclusive Calibration Wire method makes calibration and operation of our instruments simple, reliable, accurate, and foolproof, even for moderately skilled inspectors and under adverse operating conditions.

•  This straightforward and rather intuitive relative calibration method can be performed in situ for each inspection individually. It provides a functional check of the equipment for each field inspection. Moreover, the Calibration Wire method makes calibration completely independent of instrument parameters and settings, a feature that makes annual factory calibration of our equipment redundant. In addition, it establishes a reference position along the length of the rope that can be used for locating and visually verifying deteriorated rope sections.

•  The Calibration Wire method is particularly convenient when used together with our NDT_CARE™ (Computer Aided Rope Evaluation) software.

•  With 30+ years of experience, we are the only manufacturer of nondestructive wire rope test equipment that can offer this level of sophistication.
