Abstract
PURPOSE: To provide simple-structured and easy-to-handle detector for damage of rope wire strand by detecting elctromagnetically the leak magnetic flux of wire rope which varies according to damage by use of the detector with the wire rope guide groove of a given shape.
CONSTITUTION: The detector 13 is provided with the guide groove 17 whose width is a little larger than the diameter of the wire rope 4 and whose depth is 1.2 times larger than the diameter of the rope 4, and it detects electromagetically the leak magnetic flux which varies according to the damage of rope 4 magnetized by the coil 15 of coiled section 18. In this system, when ampere turn is increased by increasing the number of coils in the coil 15, it is possible to detect the damage of strand of rope 4 without the use of amplifier, etc., Thereby ensuring simple-structured and space-saving rope strand damage detector.
