Vertical coke oven machine, hydraulic coal--tamping&loading vechile
In 2008 ,we began to develop closed hydraulic stamping coal charging cars,which are equipped with vertical, side entry coke oven and ramming coal loading push coke cars.The vehicles have obtained serval national invention patents and utility model patents.
The advantages of the closed hydraulic stamping coal charging car can be listed as follows:
It saves a lot of money in the construction processas as a result of using vehicular coal bunker without coal tower .Hydraulic tamping instead of mechanical tamping .Due to the adoption of hydraulic closed and static pressure briquette,the vehicle has the virtues of low noise ,high efficiency and easy operation.Closed frame structure ,long service life (over 50 years).The vehicular coal bucker stores enough coking coal for briquettes,which improves working efficiency greatly.Low maintenance cost.Technical parameter:
