Chinese Supplier Road Construction Machine SDJK 22ton Excavator Construction Long Reach Excavators
The JKW-220 hydraulic excavator adopts a high-power, large-displacement and low-noise engine, a high-pressure low loss hydraulic system, an optimized design of the working mechanism enclosure structure and a standard reinforced digging bucket largest in capacity among its peers, able to greatly improve its reliability, durability and adaptability to various working conditions;
its reinforced chassis system can have the complete excavator achieve stronger adaptability to mining conditions and a longer service life; its pilot system is configured with customized unidirectional damping synthesis technology, so the complete machine can offer excellent performance in controllability;
at the same time, the complete machine is very good in its stability by virtue of optimization of the complete mass distribution; it is also provided with a large-capacity fuel tank, a latest air-conditioning system and an brand-new unique appearance.
This machine is mainly applicable to municipal construction, highway bridges, housing construction, road engineering, construction of water conservancy works, port construction, mines, and other earthwork construction at the advantage of sufficient flexibility, good controllability, low fuel consumption, high construction efficiency, powerful digging strength, comfortable driving environment, wide range of application and other outstanding characteristics.
