Operating performance
* The control of working device is composed of the luffing control, lifting control, and counterweight control. The reducing type pilot control valve is applied to control the hydraulic reversing valve, featuring simple controls, high flexibility and labor-saving, good fine adjustment performance, and easy arrangement on machine body.
* The hook and boom controls are integrated in one joystick and the counterweight is controlled by one separate joystick to operate under diversified working conditions conveniently and rapidly, achieve good inching performance, and guarantee the user's accuracy requirement and promote the operating efficiency.
* The hydraulic motors of hook and boom winches incorporate extremely high volumetric efficiency and the excellent balance valves eliminate the secondary gliding of winches and the jitter of unloaded hook. In addition, the clutch incorporated in the hook winch realizes the free hook lowering function.
