INSPECTION JIG AND DIAGNOSTIC METHOD FOR WIRE ROPE FOR ELEVATOR

摘要

PROBLEM TO BE SOLVED: To obtain an inspection jig which is capable of accurately and easily measuring elongation generated in a wire rope for an elevator in a short time.;SOLUTION: An inspection jig for inspecting elongation of a wire rope for an elevator includes: a jig body; a positioning section; and a scale. The jig body has a fitting section which extends in a longitudinal direction of the wire rope, is curved in a circular arc shape along an outer peripheral surface of an external coating layer of the wire rope, and is fitted to the outer peripheral surface. The positioning section is provided in the fitting section and can be aligned with an arbitrary index of a plurality of indexes formed on the external coating layer. The scale is provided in the fitting section and displays whether space between the arbitrary index and another index adjacent to the index exceeds a specified value to be a reference for rope replacement in a state in which the positioning section is aligned with the arbitrary index. Of the positioning section and the scale, at least scale is formed along a circumferential direction of the external coating layer.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2017,JPO&INPIT
