Another sensor (4) is arranged nearby a middle plane of each wheel set for measuring concentricity deviation of center section of a shaft. Sensors (5) are arranged for measuring concentricity deviation of side piece of the shaft. The sensors (4, 5) are optical sensors. USE - Used for inspecting geometric quality of wheel sets of railed vehicles. ADVANTAGE - The provision of sensors enable multiplicity of measurements to be done over periphery of the wheel set with high measuring accuracy and low working hours.de608utility model202005018753
