Customized 900mm rail gauge CJY7/9GB Mining Trolley locomotive suppliers

The working process of the overhead electric locomotive is that after the high-voltage alternating current is stepped down and rectified by the traction converter, the positive pole is connected to the overhead line, and the negative pole is connected to the rail. The pantograph on the overhead line locomotive is in contact with the overhead line, and the current is introduced into the car, and then enters the traction motor through the air automatic switch, controller and resistance box to drive the motor to run. The motor drives the wheels to rotate through the transmission device, thereby pulling the train to travel. The current from the motor flows back to the converter through the track.
The 7 Ton Electric Trolley Locomotive has 2 kinds of working rated voltage: 250V or 550V. It applies primary driving way speed control of resistance IGBT or VF type. Main features include: short wheel base high sitffness body and good shickproof performacee.
