Performance Evaluation of Cage and Skip Winder Ropes in a Uranium Mines using Two Nondestructive Testing Instruments

Electromagnetic nondestructive evaluation/testing (NDE/NDT) of wire rope has been in use for over fifty years. The electromagnetic nondestructive test is defined to be any test or measurement method for inspecting or evaluating materials or products which does not adversely affect their serviceability and which use the effects for electromagnetic induction, electromagnetic fields, or varying currents for probing, measuring or inspecting. Regular NDE inspections provide a powerful tool in monitoring the rate of degradation of a rope. The effective technology for these devices depends on the magnetic properties of steel wire rope. An attempt has been made in this paper to evaluate the performance of cage and skip winder ropes in a uranium mines in India.
