ZT-35/55F Small Horizontal Directional Drilling Machine

The Drillto ZT-35/55F is a high-performance small horizontal directional drilling machine (HDD rig) designed for efficient trenchless construction projects. Integrating advanced hydraulic and power system technologies, this rig delivers reliable operation, strong power output, and excellent maneuverability, making it ideal for urban pipeline laying, communication cable installation, water supply and drainage engineering, and other small to medium-sized trenchless construction scenarios. With its compact structure and small footprint, it can adapt to narrow construction sites, greatly improving construction flexibility and efficiency.

Core Product Features

1. Famous Brand Hydraulic & Power Systems: Equipped with the American Bomke quadruple hydraulic pump as the main pump, ensuring stable performance and high reliability. The hydraulic system and power system adopt well-known domestic and foreign brand products, laying a solid foundation for long-term continuous operation and reducing maintenance costs.
2. High-Efficiency Plunger Motor Rotation: The rotation system adopts a plunger motor, which boasts fast rotation speed, high working efficiency, and low heat generation. This design effectively improves the drilling speed and reduces energy consumption, ensuring smooth drilling operations even in complex stratum conditions.
3. Patented Technology for Enhanced Pullback Force: Utilizes patented auxiliary cylinder technology, which is simple and practical. The pullback force is increased to 55 tons (550kN), enabling the rig to handle various tough construction tasks, such as drilling through hard soil and small rock layers.
4. Three-Speed Acceleration for Multiple Speeds: The feeding speed, pullback speed, and rotation speed are all upgraded to three-speed acceleration. Operators can adjust the speed according to different construction stages and stratum conditions, optimizing construction efficiency and ensuring drilling precision.
5. Compact Structure & Small Footprint: The rig features a compact design with dimensions of 6800*2200*250mm and a weight of 10500kg. It requires a small construction area, making it suitable for construction in urban areas, narrow lanes, and other spaces with limited space.
