Developed by our company, 22-ton excavator adopts the negative flow control hydraulic system and international famous engine, hydraulic pump, control valve and travel system. The engine speed is controlled in terms of the load. With auto-idling function, the machine can make response to the movement of the lever automatically. Featuring high fuel economy, the machine can operate in various working conditions to get maximum efficiency.
The control valve integrates the function of the boom and arm confluence. When the arm is reaching and boom lifting, the front and rear pumps integrate the working flow to accelerate the moving speed. With the descending lock valve, the boom features the slewing priority.
