OFFER AND REALIZATIONS
Reprofiling of rails in track and turnouts
For many years, we have been providing the service of reprofiling of rails in track and turnouts in PKP PLK lines, trams and foreign managers of railway and tram infrastructure in two technologies: milling and rotary grinding.
Thanks to reprofiling, is is possible to significantly extend the life of the rails by reducing or eliminating defects altogether, restoring the correct profile and improve travel comfort by reducing noise levels.
Our examples of work accomplishments:
Mechanized rail reprofiling service along with measurements for PKP PLK for the period 2017-2019
Rail reprofiling service on the railway line No. 22 on the Radzice - Radom section in the period June 2018 - July 2018
Range: 13.5 km
Rail grinding service to eliminate corrugated wear in tram and railway rails in Wrocław in September - November 2018
Range: 12.2 km
Service of reprofiling of rails and switches on the railway No. 68 on the Lublin - Kraśnik section in the period January 2019 - June 2019
Range: 38 kmt and 15 switches
Service of reprofiling of rails and turnouts on railway route No. 68 on the Kraśnik - Stalowa Wola section in the period June 2019 - October 2019
Range: 60 kilometers of track and 34 switches
Mechanized rail reprofiling service along with measurements for PKP PLK for the period 2020-2022
Rail measurements in tracks and turnouts
We carry out all the needed measurements together with documentation required by the national Technical Conditions for Reprofiling rails in tracks and turnouts (ID-104 cz. I i II) and European standards (PN-EN 13231-3).
Measurements include:
- longitudinal profile
- transverse profile
- roughness measurements
- Eddy-current rail surface inspections
We have modern measuring equipment, that allow us perform work without track closures.
Rail and turnouts welding
We have acquired nearly 30 years of experience in the regeneration of rail steel components by rail welding and grinding while maintaining the highest quality and obtaining the best effect. Our knowledge allows us to perform welding work on all elements of railway turnouts (bow rails, wing rails, spiers, resistors) as well as rails built in stations and tracks (removal of the effects of train wheels spinning, etc.).
We have all the required approvals for these works issued by PKP PLK S.A. and we have been carrying out such work all over the country for many years.
Our examples of work accomplishments:
Repair of welds / welds by regeneration of the rail head by the method of arc welding directly in the track on the Railway Line No. 4 (CMK) Grodzisk Mazowiecki - Zawiercie in the period July - August 2018
The service of regeneration of turnout parts on Railway Line No. 65 in the period September - November 2018
Service of regeneration of rails, switches and track crossings by means of arc welding directly on the tracks of railway lines managed by PKP PLK S.A. in the period May 2018 - December 2020
The service of running repairs (surfacing of steel elements of turnouts) of track infrastructure in the Małaszewicze transshipment area in the period September - October 2019
Thermite rails
We perform thermite rails welds for the need of investment works (building turnouts, replacement of rails) as well as maintenance and repair works (liquidation of cracks, expansion of tracks).
The technology we use is approved by PKP PLK S.A. and we have all the necessary approvals for its use.
Our examples of work accomplishments:
Execution of thermite welds on Railway Line No. 7 on the Nałęczów - Lublin section between June 2019 and October 2020
Execution of thermite welds at Czeremcha station in the period September - October 2019
Performing thermite welds at Lublin station in August 2019
Single and two-rail track grinders
We manufactured our own construction grinders used for grinding rail elements. They have been used by ourselves for many years and current models are the result of our welders experience.
Since the beginning of production, we have delivered hundred single and two-rail grinders to service companies, managers of railway and tram infrastructure both in the country and abroad. Our products adapter to work on various track widths and rail profiles.
Welding services tailored to individual needs
We provide welding services on a special order for customers using custom solutions in the
industry. We regenerated, among others steel elements of machines, devices and tools used in heavy industry and mining.
Due to the individual nature of this service, please contact us directly a tour e-mail address: office@karya.pl in order to prepare the right solution for your requirements and expectations.
