Title:
WIRE ROPE INSPECTION DEVICE, WIRE ROPE INSPECTION SYSTEM, AND WIRE ROPE INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/054314
Kind Code:
A1
Abstract:
This wire rope inspection device comprises an excitation unit that applies magnetic flux to a wire rope (W), and a detection coil (20) that detects magnetic flux of the wire rope (W) while moving relative to the wire rope (W). The detection coil (20) is configured so that a sensor separation distance (D1, d1, D2, and d2) can be changed, the sensor separation distance being the distance from the detection coil (20) to the wire rope (W) in a direction orthogonal to the direction in which the wire rope (W) extends.
