Strength interpretation of non-destructive testing of steel ropes and steel-cord conveyor belts

Magnetic NDT instruments detect faults in steel ropes and steel-cord rubber belts such as local wire breaks, steel cord ruptures and decrease of metallic rope or belt cross section due to corrosion and/or wire deterioration (Sukhorukov, 2001 and Langebrake et al., 1998). Decoding the local faults (LF) record and loss of metallic area (LMA) record demonstrates the distribution of wire/steel-cord rope breaks and wire loss along the inspected part of the rope or the belt. For a decision upon the strength of the tested object, NDT data are interpreted by a mechanical approach into strength parameters which can serve as working capacity diagnostic indicators (Volokhovsky et al., 2003).
