Extending the Useful Service Life of Wire Hoist Ropes using Nondestructive Testing
Can nondestructive testing (NDT) be used to accurately estimate the residual strength of wire ropes in order to determine the remaining useful life of the rope?
Need and Benefit
Many Reclamation sites utilize wire ropes that are approaching the end of their expected life cycle (~15-20 years). NDT could potentially yield results that suggest that the wire ropes are still suitable, while other criteria recommend replacement. If deemed more pertinent, the utilization of NDT could prevent premature replacement of ropes therefore extending the usable life, and reducing capital expenditure. Reclamation will also be able to improve dam safety, by utilizing NDT to examine wire ropes for personnel elevators, gate hoists, and the various cranes throughout Reclamation.
