Abstract

See full text

A method of wear detection of a coated belt or rope includes connecting a wear detection unit to one or more monitoring strands and/or cords of a coated belt or rope. The coated belt or rope includes one or more baseline strands and/or cords exhibiting a first change in electrical resistance as a function of bending cycles of the belt or rope and one or more monitoring strands and/or cords exhibiting a second change in electrical resistance as a function of bending cycles of the belt or rope, greater than the first change in electrical resistance. An electrical resistance of the one or more monitoring strands and/or cords is measured via the wear detection unit. Using at least the measured electrical resistance of the one or more monitoring strands and/or cords, a wear condition of the belt or rope is determined.
