In addition to different tonnage models, at the same time, there are explosion-proof battery electric locomotives specially applied to coal mines and other mines with explosion risk. In addition, there are many other configurations to choose from, such as gauge, speed regulation, braking mode, working voltage, and so on.

Speed control mode can be selected: in the cost of above, frequency conversion speed control > chopper speed control > resistance speed control. In addition, according to the actual mine conditions, if it is a coal mine, can not use resistance speed control, because the operation is very easy to cause sparks, there are safety hazards, it is recommended to use chopper speed control or frequency conversion speed control. At the same time, to achieve the effect of energy saving and power saving, also recommended the use of chopper speed control and frequency control, resistance speed control is relatively energy-consuming. And coal mines require to equip with gas cutoff meter.
There are various models of battery motor trucks, and different models of battery motor trucks are suitable for different usage requirements.
Take CTY8 as an example, its one complete model code is CTY8/6GB.
CTY refers to mining battery electric motor vehicle, such as CTL is double driver's cab.
The first number (8) represents the tonnage of the model, and the main models are CTY2.5, CTY5, CTY8, CTY12 and so on.
The number (6) after the slash represents the gauge, generally 6, 7 and 9 represent 600mm, 762mm and 900mm respectively.
G, on the other hand, refers to steel wheels. At the same time G also stands for is resistance speed regulation, GB is chopper speed regulation, GP is frequency conversion speed regulation
