China-Made SEM 919 Motor Grader Used Machinery SEM918 Shan Gong Grader 140K on Sale
SDEC engine is more energy-efficient and environmentally friendly, with optimized axle load ratio for improved traction performance. Equipped with internationally renowned brand PPPC (Proportional Priority, Pressure Compensation) control valve for the variable displacement piston pump, enabling power distribution according to demand, reducing energy loss and hydraulic system heat generation. Flow is proportionally distributed, allowing multiple compound actions to be performed simultaneously for high construction efficiency. Direct connection between the variable displacement piston pump and the transmission ensures high transmission efficiency, reduces vehicle working noise, and enhances overall performance. Standard floating function of the shovel blade reduces operational difficulty and operator workload, effectively improving construction efficiency. Upgraded dryer and air reservoir optimize the braking performance of the vehicle, enhancing the safety of the braking system. Large diameter plastic fan with high airflow and excellent cooling effect ensures continuous and stable machine operation. It also reduces noise levels, improving driving comfort.
