The controller 28 is connected to a computer (not shown). The measuring trolley is a mobile tool with a short base, for example, 1 meter.

The running of the measuring carriage with measuring wheels, each of which is made in the form of a pair of cylindrical wheels with vertical and horizontal axes, equipping the wheels with cylindrical axes with sensors of the distance traveled and their interaction with the rolling surface of the rail head provide continuous registration of the distance traveled when passing rail joints and breaks on turnouts, increasing the accuracy of measuring the distance traveled.

The contact of the measuring tips with the rails is transferred to the non-wearing part of the rails, which increases the accuracy of determining the coordinates of the rail threads.

The information-recording system of the measuring trolley allows you to measure the gauge, the mutual elevation of the rail threads, the width of the grooves, the distances between the working faces of the core (guardrail) and the counter rail, the wear of the rails and determine the control values of the ordinates of the translated curves.

The proposed measuring trolley was manufactured industrially at the NPF Zavod Zavod Factory company, and equipping it with an information-recording system is carried out by instruments known in the measuring technique and this, according to the applicant, determines its compliance with the criterion of “industrial applicability”.
