Powerful
Isuzu 6WG1 high power engine,
Highly adaptable turbo engine, twist
Big torque, strong power and good responsiveness.
Meet the needs of high-intensity operations in mines.
Fuel Efficient
Optimize the fuel injection method, greatly optimize the curve, increase the economic fuel consumption area, lower fuel consumption, and save 12% compared to competing products
Kawasaki complete set of super hydraulic combination, high matching degree, small pressure loss, more energy-saving, more efficient.Engine-hydraulic system intelligent matching, flow supply on demand.
K7V280 main pump, greater output torque, electrically controlled positive flow hydraulic system, reduce the pressure loss of the hydraulic system.The perfect combination of load and flow rate greatly improves the response speed.
Kawasaki main valve, the strongest flow capacity in the industry, positive flow electronic control system, better operation coordination.
Self-lubricated copper based alloy sleeve for key joints for wear resistance and wear reduction.Optimize the hinge point of the working device to ensure the bucket excavation track, reduce the excavation resistance, Digging force is 10% higher than competing products.
Arm digging force: 365kN
Bucket digging force: 420kN
The power dynamic matching technology is adopted to dynamically match the optimal power absorption point according to different working conditions, gears and the optimal fuel consumption range of the engine, so as to achieve precise matching of engine power and hydraulic pump power.
