Basic Info

Motive Power:Electric

Product Description

Henan Zhongsui Engineering Equipment Co., Ltd would supply Diesel-Electric locomotives:

Application in main line, branch line,tunneling,metro,subway,coalmine.

Service power from 150KW to 320KW.

Traction Gauge: 600mm, 762 mm, 900 mm.

Diesel electric locomotive is take diesel VOLVO generator as power source, through AC-DC-AC frequency conversion, narrow gauge used mechanical electric diesel locomotive, it used for tunnel, metro , subway tunneling construction traction, of shield back-up machinery.

* Double-side brake shoes

* Two steps deadman switch to activate both eclectrical brake and air brake

* Speed meter & milelage meter

* Mini fan in driver's cab

* Sanding system for wet track conditions

* Warning light

* Wilson Coupling

* Air brake and fail safe spring loaded brake

* Fire extingurisher

* 2 set of CCTV system, wireless control with monitor

Small tunnel diesel electric locomotives's feature:

1. Weight from 25t,35t,45t,50t,55t

2. Welded steel structure frame,dc-ac frequency inverter, can be used in every tunnel harsh condition

3. Import VOLVO generator,sound noiseless,emission reach Euro standard, performance is stable and reliable.

4. apply for tunneling, long metro,subway,railway,railroad,watering tunnel, city utility, public pipeline tunnel, etc.

5. Diesel locomotive convenient to add oil, the diesel locomotive train engin no need change battery and long time charging,brake shoe wear are very less.

6. Start steady, avoid impact for drive system, greatly extend the dynamic system lifespan.

7. The diesel locomotive within its long lifespan, are very few maintenance, the motor generator engine is adopt import generator, stable performance,wear part replace cycle is long, daily maintenance is very few.

8. Good traction charactor,due to the frequency is stable,so the diesel locomotive adhesive factor reach 0.28(battery locomotive is 0.2).

9. Good braking performance.more reliable and high efficiency.brake operation is very simple,batter than battery locomotive.

10.PLC control, SIMENS diaplay system, Volvo generator, famous domestic parts manufacturers, strong quality rechack system, rich experienced technical engineers team, all enable us provide with high quality diesel locomotives.

11. Support for tunnel gradient loop at 35%.

12. Running time is long,large traction,high work efficiency,large power,running stable,suit for long journey tunnel constructions.

13.Intelligent control function:  2 set of CCTV system, clean emission
