Features of trenchless horizontal directional drill rig

• Equipped with high-quality hydraulic components, combining closed and open load-sensing circuits to enhance operational efficiency.
• The rig is divided into three main parts: power unit, main body, and an independent control cabin, which facilitates transport and deployment.
• Dual power system design enables flexible switching between dual and single modes, providing energy savings and ensuring continued operation in the event of a failure.
• The control system integrates electronic and manual controls, with the main control valve sourced from internationally renowned brands for high reliability.
• Multiple parameter display methods make monitoring of pressure, torque, speed, and other data clear and convenient.
• The rotation of the power head is driven by four imported low-speed, high-torque motors, featuring two-stage stepless speed adjustment and floating spindle design for effective protection of drill rod threads.
• The thrust/pull system is driven by six motors with a gearbox, utilizing gear and rack transmission for stable and efficient operation.
• The independent control cabin is equipped with air conditioning, providing an optimized and comfortable working environment.
• The breakout and clamping device features adjustable spacing, automatic centering, and full-travel movement, ensuring precise and stable breakout operations.
• The rig uses imported high-performance gearboxes, delivering strong power and excellent climbing ability.
