Abstract:

This study evaluates some of the LMATM series instruments for the inspection of wire rope that have been developed by NDT Technologies of South Windsor, CT. These are small units, based upon the measurement of magnetic flux leakage, and appear to be well-suited for the inspection of portable cranes despite some limitations. In contrast, most devices using this method of flaw detection are large and heavy, and are only appropriate for use on mining hoists. Safety assurance of wire rope has long been an area of concern to the navy. Current manual inspection methods are slow, tying up equipment for a long time, and present significant hazards to the inspector. In addition, the current wire rope inspection standards, based upon the limitations of manual inspection, are not appropriate for the newer wire rope inspection devices and must be modified if these devices are to see more widespread use.
