Frame
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 trolley line 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.
Brakes
Pneumatic brake to the four wheels by brake shoes. Stop brake by manual mechanical brake.
Sanders
Pneumatic (or mechanical) sanding system to the rails.
Buffers and motor suspension
The locomotive has two buffers with spring shock absorbers to achieve complete shock absorption against collisions. Equally, the motor is suspended from the chassis by a spring brace.
