Battery locomotive has general type, explosion-proof type two, electric locomotive using IGBT chopper speed regulation and frequency conversion speed regulation technology.
Underground mine battery locomotive are designed for horizontal rail transport especially in mines and enclosed spaces. They are also intended for use in potentially explosive environment with coal dust and methane in volume up to 1.5 %. They can work on slopes of rail lines up to 35‰ , with track gauge from 500 to 1060 mm, at ambient temperatures from -20°C to +40°C.
Locomotives are with single cabin and two cabins weighing from 2.5 t to 18 t. Cabins are removable, due to a simple transport into underground tunnels. Transmission of torque moment from the electric motors is through the axle gearbox to travel wheels. The chassis is of dual-axle type and travel wheels are secured with interchangeable rims. Suspension of locomotive is provided by elastic rubber-metal blocks of sagittal shape or by means of springs in accordance with the track quality.
The main features: the whole machine structure is reasonable, explosion-proof performance is reliable, high efficiency and energy saving, starting torque is large, stable operation, using multiple protection devices, less maintenance, while with electric braking function, locomotive performance is more safe and reliable.
