Technical Details Of Our Underground Horizontal Boring Machine
Every underground horizontal boring machine we make uses high-quality steel and standard hydraulic parts. This ensures the rig does not stop working midway under the ground.
Power System And Motor Options
The engine is the heart of the drilling rig. Our small model uses a 97KW or 100KW engine. Our large models use a 160KW engine.
- Cylinder Drive Type: Models like YG-160A and YG-320 use hydraulic cylinders to push and pull. This type gives a very steady movement when you go through hard clay.
- Motor Drive Type: Models like YG-180, YG-280, and YG-320A use hydraulic motors for pushing and pulling. This type offers faster moving speeds up to 20m/min or 30m/min. It saves time when you add or remove drill rods.
Torque and Rotational Speed
The powerhead needs to turn the drill pipe constantly. If the earth is hard, you need high torque.
- YG-160A and YG-180 provide 5000N.m to 6000N.m torque. This is perfect for small gas pipes and optical cable lines.
- YG-280, YG-320, and YG-320A provide 10000N.m to 12000N.m torque. This strong turning force can spin big reamers through thick earth layers.
Mud Pump Integration
Mud is important in horizontal directional drilling. The mud cools the drill bit and carries out the dirt. Our machines have built-in mud pumps with a maximum pressure of 80bar to 100bar. The mudflow ranges from 160L/min up to 320L/min. This high flow keeps the hole clean and prevents the drill pipe from getting stuck.

How To Choose Your Next HDD Boring Machine Model
Choosing the right hdd boring machine depends on your target pipe size and your local soil type. If you choose a model that is too small, you cannot pull the pipe back. If you choose a model that is too big, it will waste fuel and space in narrow city streets.
Match By Maximum Reaming Diameter
- For Pipes Under 600mm: If your final pulled pipe diameter is small, choose YG-160A or YG-180. These rigs weigh less than 8500kg. They are easy to transport on standard trucks.
- For Pipes From 600mm To 800mm: Choose YG-280, YG-320, or YG-320A. They have 280KN to 320KN pull force. They can pull heavy HDPE or steel pipes over long distances.
Match By Drilling Angle And Space
Our machines can change the entry drilling angle from 10 degrees up to 23 degrees. If you work in a city with many buildings, you need a small machine body. The YG-160A is only 5.7 meters long. It can fit into tight job sites easily. If you work in open fields for long-distance oil or water pipelines, the YG-320A provides a long chassis for excellent stability during high-torque spinning.

Work Features Of Our Horizontal Directional Drilling Machine For Sale
Our horizontal directional drilling machine for sale is popular because it solves real onsite problems for operators. The design focuses on safety, speed, and durability.
Heavy Steel Tracks For All Terrains
Every machine is mounted on strong rubber or steel tracks. It can climb slopes and walk through mud easily. The wide tracks share the weight of the heavy machine body. This prevents the rig from sinking into soft mud.
Comfortable Control Cabin
The control panel is easy to understand. You can see the push-pull pressure gauge, rotation torque gauge, and mud flow rate from one seat.
- Simple joystick controls for powerhead movement.
- Clear emergency stop buttons for safety.
- Comfortable seating to reduce operator tiredness during long working shifts.
Standardized Drill Pipes And Connections
We use Φ60mm and Φ73mm high-tensile drill pipes. Each single pipe is 3 meters long. The threads are cut precisely by CNC machines. This means you can screw the pipes together quickly without leaks or thread damage. The drilling angle stays accurate because the joints are stiff and reliable.

Export Packaging and Global After-Sales Support
YG know that importing heavy construction machinery is a big job. As a professional manufacturer, we handle all details to protect your machine during sea transport.
Sea Transport Packaging Details
- Anti-Rust Treatment: We spray protective oil on all bare metal parts, hydraulic cylinder rods, and powerhead gears.
- Firm Fixing In Container: The machine tracks are locked tightly to the container base using steel wires and wood blocks. This prevents any movement during big waves at sea.
- Component Protection: The control panel and electrical boxes are wrapped with thick waterproof plastic sheets to block salty sea air.
Wear Parts and Technical Support
We supply a complete set of initial wear parts with the machine. This includes hydraulic seals, filters, mud pump valves, and common O-rings. If you face any operational questions during your drilling project, our engineers can assist you through online video calls within 24 hours. We guide you step-by-step on how to change filters, how to connect mud lines, and how to maintain the hydraulic system.
