Non-destructive testing of ropes

Magneto-inductive rope testing (MRT) has been THE test method of choice for many years when it comes to non-destructive testing of steel wire ropes of all kinds.

The wire rope is magnetized to magnetic saturation (> 1.9 Tesla). Defects in the rope interfere with this magnetic field, which leads to stray fields that can be measured.

In this way, a large number of rope damages can be detected at an early stage:

  • internal and external broken wires
  • internal and external corrosion
  • clamping points
  • grooves
  • notches
  • structural changes

The test is carried out quickly and easily at a speed of up to 4 m/s (approx. 14 km/h or 13 ft/s). The evaluation of the measurements is subsequently carried out by our experienced inspectors.

Large operating range

ROTEC GmbH offers non-destructive rope testing for a diameter range from 4 to 140 mm (0,16” to 5,5”) and beyond if required.

As a customer you will receive a comprehensive report with a detailed description of the rope condition and recommendations for care and maintenance.
