Kompleks-2 is an upgraded digital version of the base Kompleks with higher accuracy of measurements and a possibility of installation of additional options.

Intended application

Detection of solid-rolled wheel wear in moving trains. Transfer of the obtained information to the nearest maintenance depot.

Operating principle of the system is based on laser non-contact control of geometry of moving three-dimensional objects using triangulation position sensors. 

Distinctive features 

Non-contact measurement of of geometrical parameters of wheelsets of rolling stock during its movement at speeds up to 80 km/h in different climatic conditions.

Application of the system makes it possible to increase reliability of the rolling stock and eliminate to the greatest possible degree the possibility of accidents on the railway caused by defects of wheelsets.
