Dumper job site,Coal poured out from the overturned carriage

[vc_row][vc_column][vc_column_text]The wagon dumper is a large-scale mechanical equipment for dumping bulk materials of railway gondola wagons. According to the structure, it can be divided into rotor type, side tilting type, end dump type, compound type, etc. The most widely used is the rotor type wagon dumper. The work efficiency is greatly improved, and the fast unloading of heavy-duty trains is effectively guaranteed.



  • How does the train turn?

First, the heavy-duty shunting machine hauls the fully loaded train to the front of the dumper, and then locates it by the shifter, the car is automatically unhooked and separated, and then the dumper tightly “holds the vehicle in the arms”.

After the dumper is started, the vehicle is driven to rotate. During the operation, it will detect the fixation condition again by the oil pressure. When it is turned to 165 degrees, it will decelerate and brake. The vibrator will vibrate for 3 seconds.

After the coal unloading is completed, the puller pulls the empty car out and takes it away through the relocation platform, and at the same time pulls the fully loaded vehicle again into the dumper for the next cycle.

The tipping process seems simple but requires the precise coordination of multiple equipment and systems. After hundreds of tons of trains are “turned over”, they cannot be allowed to “run freely” immediately. Railway technicians must carefully inspect the key parts of the vehicles. Eliminate unsafe factors in time to ensure safe train operation.




  • Environmental protection god skills!

Dumping coal will generate a lot of dust, so dust prevention is also an important part of the operation of the dumper.

The negative pressure dust removal system equipped with the dumper will use water spray or spray devices to remove dust according to different conditions to ensure that the dust in the workshop is controlled at a safety standard and avoid secondary pollution.

The automated production workshop is clean and bright. Under the precise control of the operators, the equipment is working in an orderly manner, and no smog dust can be seen on the spot.
