FIELD: railway transport.
SUBSTANCE: invention relates to method and devices for detecting slides on wheel roll surface. Surface of wheel is irradiated by laser beam. Information of presence and parameters of slide is found by comparing obtained sequence of profiles of flange top by changed distance between flange top and upper edge of rail. Proposed device contains optical measuring systems 1 and 2 connected with electronic information processing unit 3 arranged at a distance from one another to permit taking measurements of flange profile of one and the other half of wheel.
EFFECT: increased speed and facilitated measurements.
