VPRS-03.3

Leveling, lining and tamping machine VPRS-03.3 is intended for longitudinal and transverse leveling of railway tracks, ballast consolidation under sleepers and sleeper butts, under bars of switches and frogs.
  The machine is used for construction of new, and repair and maintenance of the existing railroads with gauges of 1435 mm and 1520 mm with  rails types up to R-65 inclusive, with concrete and wooden sleepers bedded on the various types of ballast. VPRS-03.3 is a multipurpose cycle-operating track machine performing simultaneous or separate leveling, lining and tamping of railway track in a semi-automatic or manual operating modes both on main and yard tracks and switches. 
  The machine is equipped with an additional removable device for third rail hoisting  for operation on heavy switches with concrete bars. This device allows to lift the third rail and partially tamp a long bar in the 3rd point of for its fixation.
The VPRS-03.3 machine has a four-sleeper tamping unit that allows to have a high performance in the course of tamping the track keeping the capability to operate at switches.  The tamping unit is equipped with the automated lubrication system “Lincoln”.
Leveling systems of the machine are controlled with the microprocessor system. An on-board computed with a keyboard for processing information input  is designed:
- to collect and store information on the track condition before and after leveling and on its design parameters;
- to make calculations and produce control signals for leveling systems;
- to maintain man-machine interaction.
VPRS-03.3 is equipped with the microprocessor control system of the process cycle «Sprut-4006» implementing three modes of the machine operation:
- working – executes and controls the given cyclogram of the machine operation; 
- adjustment – serves for adjustment of the working parameters, sensor scaling and fixation of the zeros;
- test and diagnostic – allows to promptly detect and isolate faults.
It also has the function of remote diagnostics and update of the machine through GSM input at any distance from it. 
VPRS-03.3 can autonomously move along main tracks to the operation site thanks to its high traveling speed, on-board radio station, transport safety system  and automated fire detecting and extinguishing system.
The machine is designed for operation in U1 environmental class conditions as per GOST 15150, but for operation at the ambient temperature from -10°C till +40°C with non-frozen ballast.
