Electric Locomotive Electric

Electric locomotive is a kind of traction equipment for rail vehicle transportation. The power is to use the traction motor to drive the wheels to rotate, and use the friction between the wheels and the rail surface to make the locomotive run on the track. In this mode of operation, its traction is not only limited by the power of the traction motor (or internal combustion engine), but also by the friction between the wheels and the rail surface. There are restrictions on the slope on which locomotive transportation can travel. The slope of the transportation track is generally 3‰, and the local slope cannot exceed 30‰. According to the structure, there are overhead electric locomotives and battery electric locomotives.
According to the nature of the power supply, electric locomotives include DC electric locomotives and AC electric locomotives, among which DC electric locomotives are the most widely used.
According to different power supply modes, DC electric locomotives are divided into two types: overhead electric locomotives and battery electric locomotives. Most of the non-coal mines used in our country are overhead electric locomotives.
In order to adapt to different gauges and transportation volumes, locomotives are divided into standard gauge locomotives and narrow gauge locomotives.

According to different occasions, it is divided into locomotives for open-pit mines and locomotives for underground mines.
