Application
  • Non-Destructive Testing equipment by MFL method for wire ropes
  • diagnostic Non-Destructive Testing equipment for crane wire ropes according to ISO 4309
  • steel wire ropes NDT system for all of lifting machineries from the special to the general industrial fields
Features
  • newly developed real-time scanning system of steel wire ropes for cranes as well as all of lifting machineries
  • The LRM equipment enables magnetic MFL testing of steel wire ropes Ф3mm up to Ф270mm
  • Testing can be performed in very harsh environmental conditions, on ropes which have plastic protective coating and are covered with grease or seaweed.
  • Original and modern solutions adopted in the LRM equipment are based on scientific work and experience on MFL methods of field inspections of steel ropes and tubes.

Technical Notice

  • LRM®-XXI Diagnostic System
    The LRM-XXI Diagnostic System for wire ropes and tubes NDT / NDE is based on the principle of saturation of steel rope section with the use of permanent magnets and obtaining the Loss of Metallic Area (LMA) traces and Local Flaw (LF) traces.
  • The use of the LMA sensor is essential in this wire rope NDT / NDE testing device for indication of a rope weakening due to internal and external corrosion, wear and other structural changes occurring on a length of a rope. LF Sensors detect local changes in a rope structure, eg. due to corrosion or broken wires.
  • Flaws are detected in a whole cross section of a rope.
    • Shape of signals from OUT LF Sensor (left)
    • Shape of signals from INN LF Sensor (right)
    • Shape of signals from LMA Sensor
    • fd - Local decrease of tested rope metallic cross section area
    • s - length of gap between wires ends
    • r - eccentrity of damade location
