CJY 3 T Trolley Locomotive For Mining

CJY 3 T Trolley Locomotives have single cabin weighing from 5 t to 20 tons; the cabin is removable for easier 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 locomotives is provided by elastic rubber-metal blocks of sagittal shape. The electric motors are maintenance-free, three-phase, asynchronous, with external cooling, and Speed and engine torque is controlled by the frequency converter. Trolleys and axle bus-bars/pantographs are fitted with carbon or aluminum strips. Engine and brake control is proportional by means of one lever in its entire range of travel speed.
