Underground 900mm rail gauge CJY7/7GB Mining Trolley locomotive Technical parameters

The working principle of overhead-type industrial and mining electric locomotive: After the high-voltage alternating current is stepped down and rectified by the rectifier cabinet, the negative electrode is connected to the track, and the positive electrode is connected to the overhead wire. The pantograph on the locomotive is connected to the overhead line, and the current is introduced into the car, and then enters the DC traction motor through the automatic switch, controller and resistance box to drive the motor to run. The motor drives the wheels to rotate through the gear transmission device, thereby driving the train to run. The current from the motor flows back to the converter through the track. The speed regulation mode is divided into resistance speed regulation, chopper speed regulation and frequency conversion speed regulation.
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.
The braking type is mechanical or electric braking or air braking safe and reliadble.
The carrying loading capacity of 7 Ton trolley locomotive could up to 70 ton.
