The wire rope on a crane needs to be replaced when the inspection results indicate that its condition has diminished to the point where further use could be unsafe.
Even regular visual inspections of crane wire ropes do not ensure the avoidance of a disaster. Visual inspection covers only 20-25% of the rope's metallic cross-section and is cursory and inaccurate.
In this reason visual inspection should be combine with all available NDT methods.
The MRT Inspection with the use of LRM XXI Diagnostic System detects defects which might not be identified by visual inspection alone.
Crane Wire Ropes Inspection Services with the use of the MRT Equipment manufactured by LRM-NDE Laboratory can detect, localize and evaluate the defects in all cross section area such as: broken wires, corrosion and wear. It allows to determine places where high temperature affects to the wire rope as well.
Damage localisation with MRT Equipment
Damage registration by LRM Rope - 21 Diagnostic Software, evaluation of MRT indications
No significant external damage from visual inspection
Section of wire rope cut off
Degradation of crane rope core - loss of 12% of metallic cross section
Regular Crane Wire Ropes Inspection according to with MRT procedure and international standards in cooperation with LRM-NDE Laboratory contributes to:
Crane Wire Rope Inspection and Inspection of Stacker Reclaimer wire ropes are performed by a person competent in the operation of MRT equipment and interpretation of trace data.
LRM-NDE provides expertise with recommendation regarding further utilization of wire ropes.
