The MRT method is a non-destructive, magnetic and contactless procedure that allows us to detect broken wires, distortions and corrosion within Steel Wire Ropes.

The MRT Method

This magnetic method was introduced in the cableways sector to inspect the haulage and carriage and to identify internal and external defects. In the 80s this technique broadened the offshore heavy lifting market due to the increasing need for efficiency and safety. Most recent versions of ISO4309 includes MRT as an assessment method for the inspection of generic heavy lifting steel wire ropes. 

MRT devices are equipped with two different signals (on two separate electrical circuits) that are used to identify and estimate damages such as both internal and external broken wires and corrosion. 

The LF Signal is the main technique in this field and it is completely regulated by international standards.
