21-ton excavator Advantages
The twin-turbocharged engine has strong power for high altitude and large workload conditions, and good adaptability to working conditions.
Each action of the whole machine is independently controlled, intelligently merged, and has fast response, high flow distribution efficiency, fuel saving and high efficiency.
The large-displacement main pump has sufficient flow supply, faster movement and higher efficiency.
High-strength chassis, solid structural parts, stable operation
Equipped with Lingong’s classic mature platform chassis, good operating stability, strong wear resistance, good impact resistance, and long service life.
Reinforced working device and frame, robot welding, weld flaw detector detection, shot blasting, stress reduction, high reliability.
