Name: Battery powered electrical mine locomotive
Model No.: CAY14/7/9
Battery-powered locomotive
1.good sticking 2.big traction3.wide range of speed regulation4.high reliability
It is DC-AC driving, narrow rail battery powered mining locomotive, suitable for transportation tracting on the narrow rail for the field of coal, metallurgic,mine,forest, railway,road turnnel construction and etc.
The company take the good advantages in the field of mine control system in recent years, applied advanced AC frequency transform speed control technology, developed battery locomotive with different voltage, different spread of track, different weight of trolley locomotive, the weight have 7t, 8t, 10t, 12t, 14t, 18t, 20t, 25t, 30t, 35t, 40t, 45t, 50t, 55t.
The AC frequency change electric motor take the technology of low speed high torque to control speed, convert battery DC to three phase AC by big power IGBT parts, driving three phase asynchronous motor, using asynchronous motor 's cliffy torque, rotate speed with advanced control technology, which improved the locomotive adherence ratio significantly. Electric braking used for normal speed gear down, which decreased the abrasions for shoe block and wheel band, and decreased the running maintenance cost.
The more significant feature is traction invert control the starting, speed control, direction change and braking, which decreased energy consumption, have good electric-saving effect. Invert have shake-proof, damp-proof and dust-proof function, the control loop controlled by 24V, 0.5A light current, with good safety performance, with interlock function when direction change, which avoid damage if driver using anti-vehicle braking. The locomotive with simple construction, low defective rate, easy to maintenance.
