Wire rope inspection system and positioning method for wire rope inspection system

A positioning method for a wire rope inspection system, comprising the steps of:

• attaching a positioning jig configured to adjust a relative position of a stationary unit fixed in proximity to a wire rope that is an inspection target with respect to the wire rope such that a detection unit configured to detect a magnetic flux of the wire rope is arranged at a predetermined position with reference to the wire rope;
• setting a positioning mechanism configured to position a detachable unit with respect to the stationary unit by adjusting a position of the stationary unit such that the positioning jig is arranged along the wire rope, the detachable unit being provided with at least a detection unit and being configured to be detachably attached to the stationary unit;
• and
• positioning the detachable unit with respect to the stationary unit by the positioning mechanism by which the detachable unit has been positioned by attaching the detachable unit to the stationary unit to detect the magnetic flux of the wire rope by the detection unit.
