1.The main parts such as the engine, main pump and valve and slewing mechanism purchase through international bid.
2.Dual pump and dual circuit high pressure variable, cross power adjustment, reverse flow control, and engine power that can be made full use of.
3.The advanced Mechatronics control system, has various power selection modes designed according to different working modes; the electronic monitoring system inspects the whole working conditions all along and displays relevant failures with sound and light alarm.
4.Slew priority, arm combination, stick combination, arm regeneration, which make working devices running stably and with high efficiency; arm retains, stick retains, and avoid subsiding.
5.With the priority of traveling, it takes hydraulic countershaft drive system, which is independent, making the machine swerve easy and smooth.
6.The cab is ergonomics designed, with heating and air conditioning and good visibility and comfort operation.
7.It serves widely in soil and rock excavation, loading and unloading and leveling off in road construction, airport and port construction, urban construction, municipal construction and pipe laying.
