The double-station operation of the turntable and working bucket is safe and convenient. The working arm can rotate 360° in all directions, effectively expanding the scope of work and improving work efficiency.
The 20-meter empty operating vehicle adopts the original imported German Hawe solenoid valve (main control valve), proportional valve, and proportional handle; electro-hydraulic proportional control, stepless speed regulation, superior operating performance; two operations on the turntable and working bucket, and both can be operated Remote control of engine ignition and flameout; built-in combined leveling mechanism to ensure that the working bucket is always level;
