Introduction of 

Underground Mining Overhead Line Locomotive

CJY 7T overhead Line Locomotive using DC electrical line, DC transformed to three phase AC by computer traction transformer, the voltage and frequency can be adjusted, which can drive two AC asynchronous motor, by reduction gear driving axle to tract locomotive.
The core parts of traction transformer using 32 digital DSP chip, fast speed with quick response.

CJY 7T overhead Line Locomotive braking is performed by two independent systems on both axles: electrodynamic – it means by electric motors through mechanical gears and mechanical – it means by mechanical dual circuit brake and by mechanical action through direct linkage to travel wheels. Brake control is proportional and maximum brake force/stopping power is self-adjustable. Parking brake is automatic. The security system provides automatic stop of the locomotive engine in a case of failure mode and when exceeding the temperature and pressure limit values. The driver is informed about all conditions on the dashboard, and such information is saved into control system memory
