Loading-transport railmotor car МПТ-Г

The railmotor car is a self-propelled vehicle on two two-axle bogies with common drive (drive for one bogie).

Short description
The railmotor car is a self-propelled vehicle on two two-axle bogies with common drive (drive for one bogie).
A bearing cab with a load-lifting crane is located on the front stand. The load-lifting telescopic crane executes mounting and dismantling the contact system masts, loading and unloading various cargo. Crane-manipulator MKC is located on the rear stand, it allows serving a trailer four-axle platform.

Destination
Loading-transport railmotor car МПТ-Г is destined for:
▪ execution of loading-unloading works and cargo transportation when current maintenance and repairs of a railway track;
▪ transportation of the working teams;
▪ shunting works;
▪ serving two trailer four-axle platforms;
▪ supply the consumers with electricity in a field condition.
