3 Ton Mining Trolley Locomotive for Underground Tunnel Trolley electric locomotive is a kind of rail transportation traction equipment, powered by transformers and overhead lines. Mainly used in mines where there is no risk of explosion. Because of its special power supply mode, the trolley electric locomotive has no limit on the cruising range. Therefore, it is suitable for long-term and long-distance use. 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.
