The system is designed for contactless automatic measurement of geometrical parameters of railway wheels and uses a combination of 2D laser scanners, mounted wayside in the track area.
The system can be easily installed at any type of rail infrastructure.

The system uses a combination of ten (fourteen for tramways carriages) RIFTEK special 2D laser scanners, RF627 Series mounted wayside in the track area (5 (7) pcs for every track side) and calibrated into one common coordinate system. Measurement cycle starts when an inductive sensor detects a wheel.
While the wheel passes through the system of synchronized 2D laser scanners its profile is taken at many sections.
All measurement readings for all the wheels are sent through Ethernet to control computer for profiles reconstruction and dimensions calculations.
Finally, all the data are collected in the host depot computer in wheel sets wear database.
