Magnetic Rope Testing for Crane Wires

Certified Magnetic Rope Testing for Crane Safety

Crane wire ropes are critical load-bearing components, and hidden internal defects can lead to catastrophic failures. Conbit’s Magnetic Rope Testing (MRT) service detects broken wires, corrosion, and core damage inside the rope—issues invisible to visual inspection. Our certified technicians use calibrated MRT equipment to ensure compliance with OEM and international standards, safeguarding your lifting operations.

How Magnetic Rope Testing Works

Technical description: MRT uses magnetic flux leakage technology to scan the rope’s entire length. When the rope passes through the magnetic field, internal flaws disturb the flux, which sensors detect and record. This method identifies broken wires, corrosion pits, and strand/core deterioration without dismantling the rope.

Step-by-step procedure:

o   1) Pre-inspection planning (rope data, crane configuration, access points).

o   2) Rope cleaning and preparation for accurate readings.

o   3) MRT equipment setup and calibration.

o   4) Rope scanning along full operational length.

o   5) Data acquisition and interpretation by certified technician.

o   6) Detailed reporting with defect locations, severity, and replacement recommendations.

Why MRT matters: Visual checks miss internal damage. MRT ensures compliance with ISO 4309 and OEM rope discard criteria, reducing risk and extending rope life.

Conbit can assist: We provide MRT inspections worldwide, onshore and offshore, integrated with your crane maintenance schedule.
