The tensioning hydraulic cylinder automatically adjusts the tension of the track chain through hydraulic pressure to adapt to different loads and terrain conditions. Its automatic adjustment mechanism reduces the need for manual adjustment, improves the adaptability and reliability of the cutting machine. The central rotary joint allows the hydraulic oil pipe and cable to pass freely when the cutting machine rotates, ensuring continuous transmission of power and control signals. It ensures the stability of power and control during the rotary operation of the cutting machine, improving the flexibility and continuity of the operation. The walking motor controls the walking speed and direction of the cutting machine, which is connected to the pedal or handle operation in the control system.

As the main power source, the engine provides the high power output required by the cutting machine, ensuring the continuity and efficiency of the operation. The battery provides backup power for the cutting machine, which is used to start the engine and power the control system when the engine is off, ensuring that the cutting machine can start and run normally without external power supply, improving the reliability and flexibility of the equipment. Components such as air filters, engine exhaust systems, and water tanks ensure that the engine runs in the best state. The second hydraulic pump can receive power from the engine to convert mechanical energy into hydraulic energy, providing power for the cutting machine's walking system and control system, which provides efficient energy conversion to ensure the stability and accuracy of the cutting machine's walking and operation actions.

The walking pedal converts the operator's foot movements into electrical or hydraulic signals to control the walking speed and direction of the cutting machine, allowing the operator to control the walking with their feet and focus on the operation with their hands, improving the flexibility of the operation and the coordination of the operation. The power supply master switch controls the power supply of the entire system; the air conditioning and heating control switch provides a comfortable working environment for the operator; the throttle rotation lock is used to fix the throttle position, maintaining a constant engine power output, which can avoid accidental changes in the throttle position in situations where stable operation speed is required, ensuring the continuity and stability of the operation. The central computer integrates the control logic and data processing of the cutting machine, receives signals from the operating handle, walking pedal, etc., and controls the hydraulic system to perform corresponding actions.
