LRM XXI Wire Rope Diagnostic Systems

Laboratory LRM-NDE provides the most innovative Wire Rope Diagnostic System for Magnetic Rope Testing (MRT) method in Non-Destructive Testing (NDT). The LRM®XXI Wire Ropes Diagnostic System can help to increase the safety and lifetime of wire ropes.
 

The LRM®XXI Diagnostic System is very helpful in evaluating the technical condition of the tested wire rope in full cross section and in full available length of wire rope in the fastest way. MRT Equipment can detect weakness section of the rope expressed in percentage of loss of metallic area.

Wire Rope Testing Systems

The LRM®XXI Wire Rope Diagnostic System (Wire Rope Tester) is Portable, Handheld and Lightweight.
The LRM®XXI Wire Rope Diagnostic System enables detecting long changes in the rope cross-section due to corrosion and wear (LMA sensor) and  local changes, e.g. broken wires, corrosion pitting and other local rope damage (LF sensor).
The inspection results are said to be reliable, accurate and repeatable.
​Due to the use of Magnetic method for testing of wire ropes the external coating (e.g. grease and anti-corrosion protection) does not influence the quality of the results.
The LRM®XXI Diagnostic System is designed, constructed and manufactured to work in harsh environmental conditions.

Components of the LRM®XXI Wire Rope Diagnostic System

LRM NDE Wire Rope Measuring Head
Wire Rope Testing Systems

1. LRM® MH Measuring Head with guiding system and LRM® Encoder is equipped with: - Sensor LMA and Sensor LF:
a) Loss of Metallic Area (LMA) Sensor, enables the localization and evaluation of long changes of metallic cross section area in a tested rope, e.g. due to corrosion or wear. The
value of LMA can be expressed in percentage with reference to metallic cross section of
tested rope.
b) Local Flaws (LF) Sensor, enables the localization and evaluation of local defects  e.g. broken wires, corrosion pitting in full cross section of wire rope.

​

​

✿ The LRM® Measuring Head has smooth housing with stainless steel.
✿ The Measuring Head does not have any electronic components which are sensitive to water.
✿ IP67 protection level for sensors inside the Measuring Heads and all components.
✿ Sliders or rollers adjust the guiding system to ensure the central wire rope drive.
✿ Encoder enabling the measurement of testing speed, direction and distance of the tested rope for the Measuring Head.

Cableway Inspection

The inspection of the technical condition of cableway wire ropes with the use of LRM®XXI Diagnostic System enables to detect of the most common various of wire rope wear, such as:  external broken wires or abrasions.
LRM® Measuring Head for Cableway Inspection Services​ is equipped in two different types of sensors:

  • LF sensor, that enables the localization and evaluation of local defects, 

  • LMA sensor, that enables the localization and evaluation of long changes of metallic cross section area in a tested rope.

Due to use this two types of sensors in LRM®XXI Diagnostic System, it is possible to perform accurate diagnostics of the place of strands rope, with detection of local defects and rope deformation in the place where the strands are interlaced (broken and loosened external wires, flattened external strands).

The advantages of Cableway Inspection Services with the use of LRM®XXI Diagnostic System:

  • reduced time of wire rope inspection compared to the visual inspection while maintaining reliability to detect all local external defects,

  • maintenance a high level of safety of transported persons due to possibility of detect the weakest section of wire rope,

  • guarantee of detecting all discontinuities in the wire rope cross section along with deformations and distortions.

 
Laboratory LRM-NDE manufactures special designed measuring head for inspection of carrying ropes.

The LRM®XXI Diagnostic Systems completely fulfils the requirements of standard EN 12927:2019
