Kubanzheldormash Company is a recognized leader in manufacturing of hydraulic track machinery in Russia. If you want modern, high-quality and productive small mechanization for railway tracks, which is able to fully replace heavy track machines this is our track tool which talks for itself, wherever you are at the territory of the former Soviet Union, you will find track tools with our company logotype.

There is a long constructive way passed from the first  RGU-1 up to the latest version RGU-4M which included in itself all the remarks, complaints and recomendations of the trackmen of Russian Railways who are using these tools almost everyday.

Рихтовщик гидравлический РГУ-4М Hydraulic flattening device RGU-4 with a gasoline engine Honda(Robin-Subaru) is intended for cross shift of a railway track and shunts, laid on wooden and ferroconcrete sleepers during maintenance and repair of the top structure of a track. Engine group flatteners RGU -4M are also used during repair and  construction of  new railways.

    Hydraulic rail flattener RGU-4M (RGU-1, RGU-1M, RGU-4) consists of a metal frame, internal combustion engine and four operative parts(rail flatteners) which are connected to one(single) hydraulic pump through high-pressure hoses. The operative part consists of the hydraulic cylinder with supporting device and special cleats on the sole. Russian hydraulic track flatteners RGU-4M are designed for transverse shifting of a railway during all types of railway works.

    We equip our rail flatteners with Japanese engines (Robin-Subaru) and Italian hydro distributor, integrated in the unified working system which allows with the help of one flattener RGU-4M to perform the flattening even of the railroad switches on reinforced concrete sleepers The old model RGU1M was not able to work with railroad switches

The application of powerful internal combustion engine by rail flatteners RGU-4M allows increasing labour productivity up to 2-2,5 km during a work shift instead of 0,5-0,7 km.
