EQUIPMENT TO TEST

STEEL WIRE ROPES

with

MAGNETIC NON-DESTRUCTIVE METHOD


 We are manufacturring unique instruments to test wire ropes. The instrument's operation is based on a world renowned magnetic method developed by the AGH university in Cracow. During the rope's passage through a test head, signals created by defects are recorded by Defectograph on a paper strip chart, semiconductor memory card or transmitted to computer hard drive. Hand-held wire rope tester indicates wire breaks  by light flashes and sound.  Its sensors signals can be also recorded on strip chart or sent to computer hard drive.
The method and our instruments are recognised in many countries across the world, in application areas such as inspection of hoisting ropes in deep mines, inspection of ropeways and inspection of wire ropes in lifting equipment.

Since very first introduction in Poland 60 years ago, magnetic method and instruments were developed to obtain best reliability and easy to use equipment.

method

Presently, the method is based on magnetisation of the rope longitudinally with permanent magnets and detection of rope anomalies by magnetic sensors. Local fault LF or local defect LD type discontinuity in the wire rope, such as broken wire or corrosion pit creates radial magnetic flux leakage and LF/LD sensor detects it as the rope passes the head. Loss of metallic area LMA sensor measures total axial magnetic flux around the wire rope. This signal is proportional to the volume of steel and the change in steel cross-sectional area. It provides information about loss of steel due to missing wire, continuous corrosion or abrasion.
