This ensures flexible and precise operation of the equipment, adapting to the fine operation requirements of various construction scenarios.

8. High-Temperature Adaptability: A high-power temperature-controlled independent hydraulic oil cooler is installed on the horizontal directional drill, making it suitable for construction in high-temperature areas. The cooler can automatically adjust the fan speed according to temperature changes, achieving energy-saving effects while ensuring the stable operation of the hydraulic system.

9. Intelligent Operation System: The horizontal directional drill is equipped with an intelligent control system, which can realize automatic adjustment and display of mast verticality, automatic rotation, automatic soil discharge, automatic lifting and pouring with long auger techniques, and pile type display. The bus panel design minimizes operating errors, simplifies the operation process, and improves construction accuracy and efficiency.

10. Convenient Transport and Transfer: The undercarriage of the horizontal directional drill can be optionally equipped with transport legs, supporting remote control operation. This design makes the transport and transfer of the equipment easier and safer, reducing labor intensity and improving work efficiency.
