Crane Monitoring & Tsting

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

LRM-XXI recorder
Feature
- The microprocessor diagnostic devices, enabling recording, storage and processing of diagnostic signals from LRM-Measuring Head.
- LRM-XXI Recorder is equipped with:
  
  LCD display indicating direction, speed and length of testing
  
  keyboard enabling control of testing process
  
  speed compensation system of testing, for reducing the influence of speed on amplitude of signals from LF sensors.
  
  connection between Recorder and Measuring Head via Signal cable or RS232 cable or USB Cable Wi-Fi connection
  
  built-in rechargerble battery enabling 12h continuous work.
  
  all external elements (housing, sockets, switches) providing IP67 degree of protection.
Application
- steel wire rope real-time scanning system
- steel wire rope or cable diagnostic non-destructive testing equipment
LRM-MH measuring head
Feature
- Designed for round rope testing, which as a standard comprise
  
  LMA sensor for detecting long changes in the rope cross-section due to corrosion and abrasion effects lack of wires in the tested section of the rope.
  
  LF sensors for detecting local changes, e.g. broken wires, section loss, corrosion pits and other local rope damage
LRM-MH-LIFT (only for elevator ropes)
Feature
- Designed for round rope testing, which as a standard comprise
  
  LMA sensor for detecting long changes in the rope cross-section due to corrosion and abrasion effects lack of wires in the tested section of the rope.
  
  LF sensors for detecting local changes, e.g. broken wires, section loss, corrosion pits and other local rope damage
- NDT via two ways as A-port for total numbers of ropes simultaneously and B-port for individually
Specification
- diameterdia. Ф8 ~ Ф18mm
- Nos of fallsMax. 8 falls
- WidthMax. 250mm
