A, Introduction of Performance Characteristics
The spacious operation range of the extra long boom excavator embodies far-reaching construction purpose and it is mainly used for dredging of river channels and lakes, demolition of buildings and earth excavation.
(a)Supreme Power, High Reliability and Low Fuel Consumption
Original packaging Comings engine which is equipped with electric throttle device can adjust fuel consumption according to the engine power, realize automatic idle speed and acceleration and decrease fuel consumption. The environmental protection performance is improved and accords with environmental emission standard of European II.
Large capacity fuel prefilter and oil-water separator improves fuel quality, decreases the early wearing of fuel injection nozzle and extends the service life of engine cylinder.
The air filter uses macro-scale structure and is equipped with air prefilter to realize three-stage filtering which ensures clean air admission and decreases the early wearing of cylinder components. It particularly satisfies for harsh working environment of heavy dust and wind.
The muffler uses large capacity airflow section technology, which significantly improves the effect of muting and reduces noise effectively.
