<P>PROBLEM TO BE SOLVED: To solve a problem that, in an electric railway, a trolley line stretched above a railway track is gradually accompanied by the passage of an electric train or a locomotive, and thereby, grasping a wearing state of the trolley line in the maintenance work of an electric railway facility is one of the most important work, however, there is no accurate and easy means to know the wearing state, and it is particularly difficult at a night work time. <P>SOLUTION: A wear detector in which a parallel color belt including different colors is formed on a surface of a white strip form base with soft synthetic resin as a base material in a longitudinal direction while an adhesive layer is formed on a rear surface is stuck to a side face section of a trolley line for the electric railway so that the parallel color belt may be in the same direction as the longitudinal direction of the trolley line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
