NEW! Automatic real-time system for measurement of wheelsets geometrical parameters or "3D Wheel System"

Our new system is designed for contactless automatic measurement of geometrical parameters of railway wheels and can be easily installed at any type of rail infrastructure.

The system uses a combination of ten 2D laser scanners, RF625 Series mounted wayside in the track area (5 pcs for every track side) and calibrated into one common coordinate system.
A measurement cycle starts when an inductive sensor detects a wheel.
While a wheel passes through the system of synchronized 2D laser scanners, its profile is taken at many sections.
All measurement readings for all the train wheels are sent through Ethernet to control computer for profiles reconstruction and dimensions calculations. Finally all data are collected in the host depot computer in wheel sets wear database.


Measured parameters Accuracy
Wheel profiles +/- 0,1 mm
Flange height +/- 0,1 mm
Flange width +/- 0,1 mm
Flange angle +/- 0,2 mm
Rim thickness +/- 0,1 mm
Tread width +/- 0,1 mm
Back-to-back distance +/- 0,05 mm
Diameter +/- 0,2 mm

System tests were successful and we are working on the final version of the system to be installed in Minsk electrodepot for permanent use.
Video demonstration of the system is available on our website Real time wheels geometry measurement system page
