30 T AC frequency speed regulation,underground mining electric trolley locomotive, coal locomotive,elecric operated locomotive,AC speed regulation trolley locomotive
Application; On Rail Gauge
Service; Transportation in Mining , Tunneling and related Construction
There are three kinds of locomotive according the brake mode Resistance speed regulating mode, IGBT chopper speed regulating mode, and AC converter speed regulating mode
There are two kinds of locomotive according to the supplier of the power.
Trolley electric locomotive and battery electric locomotive
Horsepower: 60 kn
Model Number : CJY30/6,7,9GB
Track Gauge :600, 762 or 900 mm
Speed (km/h): 12.73
Brake Mode : Mechanical brake .
Speed adjusting mode; AC frequency, resistance or IGBT
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 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 brace with springs.
