Magnetic Rope Testing for the port and maritime sector

Magnetic Rope Testing allows for rigorous monitoring of wire ropes

Lifting installations using wire ropes, such as container gantries, quay cranes, offshore cranes, ship doors, and many others, require rigorous monitoring of the wire ropes. Magnetic Rope Testing (MRT) of these wire ropes, in accordance with ISO 4309, is essential for detecting defects and assessing the condition of the wire ropes.

MRT techniques, in LF mode, detect broken wires due to fatigue, while LMA mode quantifies corrosion levels, which is particularly useful in saline environments.

MRT certificates, issued by technicians certified to ISO 9712 MIT WR Level II with devices compliant with EN 12927, enhance the reliability and safety of the installations.

Visual inspection and MRT are complementary, forming a solid foundation for wire rope inspection. A thorough visual inspection would take 24 hours for a 1400 m wire rope, whereas MRT requires only the time of a complete cycle at nominal speed. MRT offers significant time savings, exhaustive defect detection, and diagnostics independent of lubrication, lighting, and atmospheric conditions.

MRT allows for the retention of data files, providing proof of the wire rope's condition. Technicians can interpret the data with confidence, avoiding errors due to visual fatigue and assessing the evolution of the wire ropes over time.
