Wholesale China St14 Battery Factories – 5 Ton Underground Mining Battery Locomotive – Dali

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.

Batteries are made of high-end aviation batteries, which are stable and durable. The locomotives are widely used in ferrous, non-ferrous and non-metallic mines.
The improved battery locomotive has the advantages of the compact and solid body.

The control assembly of the locomotive adopts PWM pulse width modulator, which has over-current, under-voltage, short circuit and multiple intelligent protection.

The pedal throttle installed in the cab can easily realize the operation control of soft start, uniform acceleration, uniform deceleration, and power-off braking, so as to make the running process of the electric locomotive more stable.
