Description
The railmotor car shunting MMT-3 on the basis of a six-wheeled tractor of HTA-300 has three axes, weight, big in comparison with XTA-200(220), the improved tires and, as a result, the big area of a prileganiye of pneumowheels to rails increased twice productivity of the compressor unit - 3,5 m ³ in min. Thanks to such characteristics the railmotor car is capable to move structures with a total coupling weight up to 1500 tons on rails.
The MMT-3 railmotor car is made in different options of a complete set:
1. it is equipped with a shelter for transportation of people, the tool and the equipment;
2. it is equipped with a body for transportation of the tool, the equipment and different loads.
