KOLTECH - Wheel Lathes and Wheelset Measurement and Monitoring Equipment

KOLTECH designs and manufactures machines and devices for city transport and railways such as underfloor and multi-purpose wheel lathes used for the reconditioning of rail vehicle wheelsets, and devices for the measurement and monitoring of flange height and wheel diameters of rail wheelsets. KOLTECH is certified ISO 9001: 2001.

UNDERFLOOR WHEEL LATHES

The TUP-650 and TUP-650H underfloor wheel lathes are designed for reconditioning the profile of rail vehicle wheelsets which load onto one axle that does not exceed 12,000daN - for the TUP-650H lathes, loads that do not exceed 15,000daN.

The TUP-650 / TUP-650H lathes are adapted for the reconditioning of profile of tramway, subway and light railways vehicle wheelsets. They are equipped with absorbing inserts for wheelsets of modern low floor tramways and take into account specific rail design features, especially the varied construction of driving and slow-speed bogies; wheelsets in drive and slow-speed bogies of subway units; and wheels of frame vehicles, mounted on axle shafts.

The turning of inner and outer faces of wheel tyres can be performed on the machine, as well as facing of the active surface of brake discs, mounted between the wheels of the wheelset.

TUP-650 received a prize in the contest for the best product during the V Exhibition of City Transport Łódź 2000 in Poland.

We also offer the TUP-650SH, an underfloor wheel lathe designed for heavy duty vehicles with single axle loads of up to 30,000daN. This lathe is based on the design solutions of the TUP-650 model.

MULTI-PURPOSE WHEEL LATHES

The multi-purpose TUU 800 / 1250 wheel lathes are designed for turning the wheel profiles of rail vehicle wheelsets (both new and used) and wheel centres. Those lathes are provided with friction drive, where the wheelset is driven by rollers.

The machine can perform the following turning jobs:

• Reconditioning wheel profile of used wheelsets
• Exposing the ring, securing the wheelset wheel tyre
• Facing inner and outer faces of wheel tyres
• Facing active surface of brake discs, mounted on the wheelset axle, both outer and mounted between the wheels

FLANGE HEIGHT AND WHEEL DIAMETER MEASUREMENT AND MONITORING

The PZK device is designed for performing automatic, contactless measurement and monitoring of flange height and thickness and wheel diameters on rail vehicle wheelsets. Additionally, measurement of distance inner faces is carried out, as well as measurement of the attacking points of wheels located on the same axle. This device is installed on the through track; for example, in a tramway depot it enables measurements to be carried out in motion

The PZK device can be installed both in pit type foundation, made in the floor, and also in inspection pits.

The sensors perform a series of wheel measurements, from which the obtained data is transferred to the PC computer, which is also the control panel of the PZK device.

The PZK was awarded with the main prize, 'GOLDEN WHEELS', in the competition for the best product during the VII Exhibition of City Transport Łódź 2002 in Poland.

RAIL SHUNTER

The rail shunter is offered for shunting tramways and other rail vehicles on sub-grade sections of the rail where travel with the vehicles' own drives is not possible and their precise positioning is required.

PZD OVERLAPPING MACHINES FOR RAIL WHEELSETS

The family of PZD 150-170 overlapping machines for wheelsets are special purpose devices, designed for overlapping of rings and securing the tyres of the wheelset wheels. The overlapping machines are universal devices, enabling the overlapping of wheels of various diameters with a wide range of speeds and overlapping forces.
