KOLTECH is specialized in the production of mechanical machines and devices for rail vehicle maintenance and repair facilities.

The underfloor wheel lathes types, TUP 650, TUP 650H and TUP 650SH are designed for reconditioning of wheel profiles of all ranges of rail vehicles.

The machining process is carried out without the necessity of dismantling the wheelsets from the vehicle.

TUP 650 lathe is designed for light rail vehicles like tramways where single axle load does not exceed 10000 daN whereas TUP 650H lathe is for e.g. traction units of subways where single axle load does not exceed 17000 daN, and TUP 650SH lathe is for railway applications where single axle load does not exceed 30000 daN.

PZK2 is a diagnostic station designed for automatic contactless meas- urement and monitoring of profile and diameter of the rail vehicle wheels. Additionally by means of this station, back to back distance between inner faces of wheels of the same axle can be measured.

This station, installed on the track in e.g. tram depots, enables the measurement of parameters in motion – at the speed of the rail vehicle up to 10 km/h from one approach direction.

It is recommended to locate the station under roof so it is protect- ed against atmospheric conditions as well as in a place of limited influence of sunlight.
