Integration of modern technological solutions — TECHVAGONMASH
Having a vast experience, highly qualified specialists, our own production and technical facilities, close ties with a number of research and production organizations, Research and Production Enterprise Techvagonmash always seeks to solve multi-aspect tasks of technical re-equipment effectively and efficiently.
Research and Production Enterprise TECHVAGONMASH is well known to railroad carbuilders as an integrator of state-of-the-art technological solutions. Its main specialization is designing and making of special process equipment for manufacturing of freight cars, public transport cars, traction rolling stock.
Establishment of our company starts in 1964, when the enterprise necessary for railroad transport factories design and equipping development – an all-union scientific research and design technology institute of railway car building (VNIPTIvagon) and a pilot factory – were being set up. The enterprise was a main technological organization on designing of railroad transport factories.
Аutomated center for railroad car frames drilling
We have implemented a comprehensive project on organization of gondola cars manufacturing at Popasnaya Railroad Car Repair Plant. The annual output program makes up 5000 gondola cars. RPE TECHVAGONMASH developed a technological part of a detail design, the plant is completely equipped with a special process equipment by RPE TECHVAGONMASH.
A special mention should go to automated center for railroad car frames drilling. Only one operator can serve this center – he should just put the frame of the assembled car on the stand with the help of a workshop crane. The frame clamping is performed automatically. After installation the drilling gantry will define the spots for holes automatically and will drill them using necessary replaceable tools.
Designing and manufacturing of wheels painting line
In 2016 we implemented a number of large projects with Interpipe company. Designing and manufacturing of wheels painting line for Nizhnedneprovsk pipe plant is among them (the company). The equipment was manufactured within the framework of establishing a new department on finishing of railroad wheels at Nizhnedneprovsk pipe plant. New facilities will allow Interpipe to output more compound products which are in demand in Europe, America and in the Middle East.
The line represents a set of equipment for performing technological operations on surface preparation and applying of different coatings on railroad wheels.
The Customer put forward serious demands to multipurposeness and efficiency of the line. The wheels of 5 dimension types with 750 — 1256 mm diameter, in addition to this the perfomance of the line has to make up 15 wheels per hour. A large variation in wheels diameter makes it difficult to load and transport wheels in automatic mode. However our design engineers applied original solutions and met the challenge.
Line for applying coatings on railroad axles
The second large project, implemented on Nizhnedneprovsk pipe plant, is the line for applying coatings on railroad axles. This equipment is a part of the project on organization of a new department on wheelset assembly. Interpipe performed the assembly of wheelsets on subcontracting basis at the European companies using their own railroad wheels and axles earlier. New facilities will allow interpipe to perform a part of assembly independently in Ukraine.
Process equipment set for SKD freight cars assembly
RPE Techvagonmash LLC was one of main designers of the plant and the supplier of complete process equipment set for SKD freight cars assembly project in Eglava (Latvia). Among the supplied equipment the multipurpose assembly stand for gondola car body is of particular interest. This stand allows reducing the labor intensity of gondola car body assembly and minimizing the manpower.
Manufacturing of the traverser and turntable for electric locomotives
RPE Techvagonmash LLC was most successful in assembly and welding equipment design and manufacturing. But we’re not complacent. Thus we manufactured the traverser and turntable for Electric Locomotive Building Plant in Astana. This equipment (load capacity up to 150t) is intended for Alstom electric locomotives transfer.
Line on manufacturing of center sills
The line on manufacturing of center sills was made for Tikhvin Freight Car Manufacturing Plant. This is a unique unit for robotic submerged arc welding of longitudinal seams of all freight cars center sill models. The unit allows performing welding of items in “normal” and “reverse” positions providing counter-deflection during welding process in order to prevent deformations.
Robots application allows flexible readjusting from one item to another very fast. Moreover we developed a fundamentally new equipment on request of Tikhvin Freight Car Manufacturing Plant – Automated drilling center for freight car center sill drilling.
The advantages of such equipment implementation are obvious: automatic item processing is performed at one set-up and operator has no need to put marks. The chip collecting conveyor provides the high production standard and reduces the time for stand cleaning. The center is equipped with independent center sills handling system. The output cycle time is only 20 minutes.
Elevated access platforms
Scientific-and-Reseach Company Techvagonmash LLC supplied elevated access platforms to CJSC Bryansk Machine Building Plant in 2016. The access platforms shall be applied in new freight mainline locomotives productions. The lifting platforms are traditionally used for car bodies processing at the enterprise, but they have plenty of drawbacks: they can’t transfer the operator at required height, making the production more complicated, they don’t meet the industrial safety requirements and they are inconvenient. The elevated access platforms produced by Techvagonmash solve all the above problems; moreover they have a vast range of extra benefits. The access platform can be elevated at set height, allowing the operator to work with cars of different height. Besides, they can travel forward, facilitating operations with cars of various widths. There are also platforms provided for the front walls moving up and down.
Equipment complex for manufacturing of double-deck cars
At the end of 2012 our company successfully finished commissioning of the equipment complex for manufacturing of double-deck cars at Tver Railway Car Building Plant JSC – an enterprise which is an undisputed leader in the sphere of public railroad transport manufacturing in CIS countries.
The order for designing and implementation of the equipment complex is conditioned by the plans of the company on development of a prospective double-deck cars market in the first place. Traditionally following the principles of multipurposeness of design solutions, the specialists of Techvagonmash created equipment capable to be fast readjusted for making of other types of passenger cars, modern electric trains and metro cars. Among the equipment supplied to Tver Railway Car Building Plant it is necessary to point out two totally new products. They are a multipurpose positioner for welding of flooring and a multipurpose jig positioner for car sidewalls. The multipurpose positioner is intended for welding of floor sheets and mounting of underfloor equipment on the frame of double-deck passenger cars.
In order to reach multipurposeness oriented to operations with frames of different-length cars, all the main elements of the positioner structure are mobile.
Welding operations are performed by means of independent mobile gantries, which move along the rail guides along the car frame. The gantries are fitted with appropriate control panels as well as ladders for workers.
In 2016 our cooperation with Alstom Corporation started. We’ve designed and manufactured equipment for tram car bogie parts assembly and processing. We met the challenge, the Customer put faith in us and I believe we have a lot of challenging work in future. Having a vast experience, highly qualified specialists, our own production and technical facilities, close ties with a number of research and production organizations, Research and Production Enterprise Techvagonmash always seeks to solve multi-aspect tasks of technical re-equipment effectively and efficiently.
