Origin of MRT
MRT was once introduced in the ropeway industry to identify external as well as internal defects and provide maximum protection to passengers. Magnetic rope testing first came into use in this sector in the 1980s, especially for special use cases. The technique later caught on in the offshore heavy lift market due to increasing demands in terms of efficiency and safety.
In the meantime, magentic rope testing has become exceedingly well established, so that the latest version of ISO4309 already includes magentic rope testing as a common assessment method for the inspection of general steel wire ropes.
The innovative magentic rope testing concept is continuously evolving: the magnetic induction method as well as the user interface are steadily improving, so that a complete steel wire rope inspection can now be performed completely automatically.
