Optimization of the power matching between the main pump and the engine achieves a reduction of more than 7% in the comprehensive fuel consumption for excavation operations. The new load hydraulic sensitive system is equipped with "eight-ton" large-diameter main valves, with a 33.3% increase in diameter, further reducing pressure loss and optimizing the handling of composite movements. Optimized and upgraded slewing torque, increased torque by 20%. The width of chassis is increased by 60mm, which strengthens and enlarges the chassis, and the solid chassis makes the excavation more stable and the operation easier.
