Latest Zoomlion Excavator

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.
(b)Advanced and reliable hydraulic control system
New complete electric control selective system
According to different working loads, design different power selection methods, perform optimum performance in the precondition of reducing fuel consumption and make the engine and the main pump power reach the best state.
B, Standard Equipments
1, Original packaging Japanese main pump: Negative power + cross power control system, flow rate of 2× 220L/min. Energy-saving, with standby function and quick response.
2, Original packaging Japanese main valve: Rotary priority valve, boom collecting valve, bucket pole collecting valve, bucket pole locking valve, straight walking valve, oil return recovery valve, breaking hammer service valve, external connected bucket collecting pipeline are assembled in the valve, which has complete functions.
3, Original packaging Japanese swing motor+ deceleration machine: With hydraulic time delay break, swing prevention valve, buffer starting valve. The impact and swing can be reduced, thus the positioning operation can be more accurate, and the life of components prolonged.
4, Japanese walking motor+ deceleration machine: With hydraulic time delay break, buffer starting valve, double walking speed automatic/manual switching, it is guaranteed that the moment and rotational speed can adjust to the ground working environment.
5, The operators can control the operations accurately. It is flexible, portable and reliable.
6, Slewing bearing: Equipped with large diameter slewing bearing, which can stand the impact, with high loading capacity, full-sealing, self-lubricating, waterproof, dustproof and pollution prevention.
