Narrow Gauge 2.5 Ton Mining Battery Locomotive Battery electric locomotive is a kind of track traction equipment powered by batteries, which is generally used in mines. There are two types of battery electric locomotives, explosion-proof type and ordinary type. The explosion-proof type is mainly used in coal mines. There are also many options in terms of speed regulation and braking methods. Speed control methods include resistance speed control, chopping speed control and frequency conversion speed control. Braking methods include pure mechanical braking, hydraulic braking and compressed air braking. In addition, electric braking can also be selected as an auxiliary braking method.
