Chinacoal07 double cabs battery locomotive, locomotive, 12 MTs double cabs battery locomotive Specifications 12 MTs locomotive battery  1. Larger capacity of the battery units  2. Low center of gravity Chassis Constructed in welded steel and suspended by leaf spring or rubber studs on grease bearing seats with tapered roller bearings. Speed control In order to achieve continuous and stepless speed regulation, they have an electronic speed controller with high reliability. The AC converters convert the DC from batteries into AC and the controller adjusts the speed of AC motors by the power frequency of the AC converter. AC motor Comparing with DC motors, the 3 phases AC motors have no carbon brushes and any other quick-wear parts. Double cabs type 8 tonner battery locomotives have double cabs type. This type have better field of vision for the operators. Brakes Pneumatic brake to the four wheels by brake shoes. Stop brake by manual mechanical brake.
