Our partner 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.
