Loading-transport railmotor car МПТ-6

The railmotor car is a self-propelled two-axle vehicle. Power plant (diesel ЯМЗ-238 Б-14) is on the rear stand under a cowl, it transmits power through a wedge-belt transmission to a three-phase generator and through a hydro-transmission and a cardan drive - to the axle reducers of the wheel pairs and a compressor.

Short description
The railmotor car is a self-propelled two-axle vehicle. A bearing cab with a load-lifting crane up is located on the front stage, diesel ЯМЗ-238 Б-14 is in the middle part under a frame. Power from the diesel is transmitted through the cardan shafts, a distributing reducer to the hydro-pumps, a compressor, hydro-transmission ГП-300 (or  ГMП-300) and from that through a cardan drive to the axle reducers of the wheel pairs and a three-phase generator.

Destination
Loading-transport railmotor car МПТ-6 is destined for:
▪ cargo loading, unloading and transporting on its own platform;
▪ cargo transportation on the trailer platforms;
▪ transportation of long-length cargo including the rails 25 m long on its own and a trailer platforms;
▪ transporting the working teams to a working place;
▪ performing shunting works on the station tracks;
▪ performing welding works in a field condition;
▪ removing a snow from the tracks;
▪ supply the consumers with 380/220 V, 50 Hz energy including lighting in a field condition;
▪ supply the consumers with 8-atm air;   
▪ use as a head machine as a part of complex for current track maintenance;
▪ cargo dragging with a crab from a side to a crane working zone.
