MRT
Magnetic Rope Testing, known as MRT is a highly effective non‑destructive testing method that detects internal and external rope defects that may not be visible during standard visual inspections, helping you make informed decisions about rope safety, replacement and maintenance.
Our MRT services are suitable for a wide range of applications, including mobile cranes, tower cranes, overhead cranes, offshore and marine cranes, mining and cableway systems, elevators and other critical lifting operations. Using specialised MRT equipment, our trained technicians can identify localised faults such as broken wires and corrosion, as well as loss of metallic cross‑section (LMA), giving a detailed picture of the true condition of your steel wire rope.
MRT complements and enhances your regular steel wire rope inspection regime, supporting compliance with LOLER and relevant industry standards. By detecting rope degradation at an early stage, MRT can help extend rope life, reduce the risk of in‑service failure and minimise unplanned downtime. Following each test, CERtex UK provides clear reporting, including data interpretation and recommendations on continued use, further monitoring or rope replacement.
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.
