Abstract
In a rope damage diagnostic testing apparatus, an ultrasound applicator generates ultrasonic waves in a wire rope by making the wire rope vibrate due to magnetostriction effect. A detecting element detects changes in a state of propagation of the ultrasonic waves in the wire rope. An excitation coil and the detecting element are disposed in a parallelogram that has as a first opposite side length a length of a portion of the wire rope in which one of the outer layer strands makes one revolution around the wire rope, and that has as a second opposite side length a product of a diameter and number of the outer layer wires that are included in one of the outer layer strands.
