摘要： A wire rope flaw detector comprises a back yoke and excitation permanent magnets, which form a main magnetic path in a predetermined section of a wire rope in the axial direction; a magnetic path member arranged in the predetermined section to be magnetically insulated from the back yoke and the permanent magnets and making the leakage flux generated from a damaged part of wire rope detour to the outside of the wire rope; and a detection coil wound around the magnetic path member for detecting leakage flux. The amount of leakage flux can be increased by providing the magnetic path member and since the windable area of the detection coil is increased, the number of turns of detection coil can be increased.

A test string is disposed in an opening of the testing recessed portion for testing a surface that is not in the vicinity of or in contact with the test edge portion.

摘要： In order to reduce noise due to the rope vibration in the rope tester, a mounting shaft extending perpendicular to the running direction of the wire rope is positioned in front of the rope tester, and a hook-shaped engagement piece, which extends from the rope tester and is slidable or rotatable into an opened or closed position, is brought into engagement with the mounting shaft so that the rope tester is held movable in the perpendicular direction relative to the running direction of the wire rope.

摘要： A magnetic flux generated by current excitation is allowed to pass through a part or an entire of a magnetic path of a leakage magnetic flux. A magnetic flux content due to the current excitation is temporally changed to change a leakage magnetic flux content interlinked with a detection coil so that an induced voltage is generated in the detection coil. Consequently, damage can be detected even in a case where there is no relative speed between a wire rope and a wire rope flaw detector. Further, a configuration of the magnetic path and the number of ampere turns of an exciting coil are set to be appropriate to prevent the magnetic flux generated by the current excitation from passing through the detection coil or to allow the magnetic fluxes offset each other. Thus, noise superimposition on the detection coil due to the current excitation can be prevented.
