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 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 ses AC motors have no carbon brushes and any other quick-wear parts. Double cabs type of 8 tonner battery locomotives have double cabs that have better field of vision for the operators.

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.

Battery

The battery housing is constructed in steel plating with an interior anti-acid covering. Each device has 55 to 72 pcs series storage lead-acid batteries.

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 springs brace.
