Equipped with original ISUZU turbo-charged engine which adopts mechanical high-pressure fuel pump and other technologies features strong power, low noise and low fuel consumption. Low Fuel-Consumption Engine Equipped with original ISUZU turbo-charged engine which adopts mechanical high-pressure fuel pump and other technologies features strong power, low noise and low fuel consumption. Automatic idle function can reduce fuel consumption and noise dramatically. Optimal Control System Adopt original Kawasaki KC-MB-10 controller which adds automatic diagnostic function, the optimal control system makes rational match between the engine and main pump， making machines work efficiently with low fuel consumption. Optimal Operating Mode The crushing mode is added to help operator use hydraulic hammer， thus get outperformance with low fuel consumption. The pipelines are also optimized through new design to reduce energy waste of hydraulic system. Upgraded Hydraulic System The hydraulic pipelines adopt upgraded high-pressure hoses to avoid damage and oil leakage. Pilot oil filter is adopted which makes hydraulic system more reliable. The advanced stress analysis technology and Q345 materials make whole structures more reliable. The front and rear support of boom are made of cast steel which effectively reduces concentration of stress, key positions are also reinforced by welding strength plate, which makes arm more robust. All the wiring harnesses adopt waterproof and dustproof connector, which has high security level and high reliability. Shut-down protection is added to reduce the failure possibility for electrical elements when power was cut-out.
