Keywords:
The EC220 excavator's internationally advanced hydraulic system provides load sensing and flow sharing capabilities, leading to operational precision, efficient performance and greater controllability. When the boom lifts and the bucket excavates, the oil will flow together in the valve to improve efficiency; moreover, the arm has a regeneration function, resulting in a faster arm speed. Digging Force Up by 11% & Fuel Consumption Down by 5%-8% Compared with the traditional model, the advanced system pressure increases the digging force. The optimized internal passage of the main valve will reduce transmission pressure loss and save fuel.
