The working principle of the Carter 320GC remote control joystick handle is based on the electronic control system. When the handle is operated, the sensor in the handle senses the movement of the handle and converts it into an electrical signal. These electrical signals are sensed by the electronic control unit (ECU), which calculates and processes them and transmits the corresponding signals to the proportional solenoid valve on the distributor through the communication line. The solenoid valve switches according to the received signal, controls the pilot pressure oil to enter the spring side of the main valve core, and overcomes the spring force to move the valve core. In this way, the pressure oil output by the pump can flow to the corresponding working device, such as the cylinder or motor, through the opening of the main valve core, to realize various actions of the excavator, such as the rise and fall of the boom, the extension and retraction of the bucket, the digging and unloading of the bucket, as well as the rotation and walking of the bucket.
