PERFORMANCE EVALUATION OF TRACK ROPES USING TWO NON DESTRUCTIVE TESTING INSTRUMENTS

Electromagnetic nondestructive evaluation/testing (NDE/NDT)of wire rope has been in use for over fifty years. Regular NDEinspections provide a powerful tool in monitoring the rate ofdegradation of a rope.Wirerope Defectograph/Rope Tester is being used for scanning of steel wire ropes in aerial ropeways. The effective technology for these devices depends on the magneticproperties of steel wire rope.An attempt has been made in this paper to evaluate the performance of four track ropes in a zigback passenger cable car installationin India using two nondestructive testing instruments.
