Wheel Lathes and Wheelset Measurement and Monitoring Equipment

Gospodarcza Street 2,
47-400 Racibórz,

KOLTECH designs and manufactures machines and devices for city rail transport and railway maintenance, such as underfloor and above floor wheel lathes, used for the reconditioning of wheel profiles of rail vehicles, and measurement and monitoring devices for wheel-set parameters.

Easy to learn, easy to use, easy to maintain

At designing of all our products, we have adopted the main rule of simple and easy learning of operating, using and servicing of the machines and at the same time of making use of the latest technical solutions.

TUP650, TUP650H, TUP650SH – underfloor wheel lathes

The underfloor wheel lathes types, TUP650, TUP650H and TUP650SH 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.

TUP650 lathe is designed for light rail vehicles such as tramways where single-axle load does not exceed 10,000daN whereas TUP650H lathe is for applications, such as traction units of subways where single-axle load does not exceed 18,000daN. The TUP650SH lathe is for railway applications where single axle load does not exceed 30000 daN.

Every model can be produced in tandem versions, with two underfloor wheel lathes located back to back that can operate two axles of one bogie at the same time.

TUU1250 – above floor wheel lathes

The above floor wheel lathe type TUU with a friction drive is designed for turning of wheel profiles of rail vehicle wheelsets both the new and the used one. The loading and unloading of wheelsets from the machine can be carried out from the floor level. The wheelset is rolled in and rolled off at the front of the machine.

PZK2 – diagnostic stations

PZK2 is a diagnostic station designed for automatic, contactless measurement of profile and diameter of the rail vehicles. Additionally with the use of that station you can perform the measurement of back-to-back distance.

The station is installed on the rail track, for example, in tramway depots and it enables the measurement of the parameters while the vehicle travels over the station at a speed up to 15km/h during the measurement process from one approach direction PZK2 station can be installed both in pit type foundation made in the depot floor and also in a revision channel.

PZK2 diagnostic station can cooperate with the underfloor wheel lathe series TUP.

WM150, WM300 and WM500 – rail shunters

The rail shunters WM150, WM300, WM500 are for shunting the rail vehicles on the rail track where the travel, performed by vehicle own drive or its precise positioning in a desired place is not possible.

The system of four wheels enables the travel along the rails in both directions forwards and backwards with adjusted shunting speed. The shunters are equipped with own double-axle drive, powered by two AC electric motors. Power is supplied by traction batteries.

PZD – ring rolling machines

The type PZD ring rolling machines are special purpose devices, designed for rolling of the safety rings in the tyres of the wheelsets. They are mainly used in repair railway workshops. The ring rolling machine is a multifunctional device; it enables the rolling of wheelset of various diameters in a wide range of speeds and rolling forces of both standard and drive wheelsets.

KOLTECH is ISO 9001:2015, ISO 14001:2015 and OSHAS 18001:2007   certified.
