The machine is a self-propelled vehicle, on which operating elements are mounted – middle and side plows, a sweeping device, a ballast conveyor, a ballast storage bin for accumulation of excess ballast and its further pouring into the necessary places.

At the same time, the ballast leveling machine can transport another machine up to 40 t, if necessary, including connection of the main pipeline of the compressed-air brake of railway type.

The machine includes the components as follows:

  • power supply unit;
  • power train arrangement;
  • undercarriage;
  • operating elements for performing technological operations for track levelling;
  • hydraulic system;
  • operating pneumatic system;
  • electric equipment;
  • hoods and fences;
  • braking system, which also provides braking when travelling as a part of train;

The machine has operating mode and transport mode.

In the operating mode, the machine creates and forms a ballast section profile.  The machine moves at a constant speed, which corresponds to the selected work method:

  • ballast movement, shaping the ballast section using the middle plow and side shares (v = up to 8 km/h);
  • sweeping and cleaning of the surface of ties and fastenings from ballast (v = up to 2 km/h)
  • In transport mode, the machine moves like a self-propelled transport unit.

The maximum self-propelled speed is 80 km/h., as a part of a train – 100 km/h.

Weight of trailer train – 40 t.

The machine can be transported as part of a train unattended.

In contrast to other machines of the same type, СПЗ-5 has a lower weight, due to which the fuel consumption is significantly reduced.
