20 ABSTRACT (Continue on reverse side II necessary and identity by block number) 



The nondestructive wire rope tester, MT 75, was investigated, tested, and evaluated 

 in order to fill the gap between the hand-held rag inspection and the large unitized AC/DC 

 wire rope inspection device. The MT 75 can provide better information on the condition 

 of the wire rope than can be obtained by using the "rag and visual" inspection method.
