A big construction company from Texas, USA, recently bought a high-quality hdd rig from YG Machinery. The customer wanted to expand their business in laying city water pipes and internet cables. They needed a machine that can drill long distances without opening the road surface. After checking many suppliers, they chose our YG-320 horizontal directional drilling machine. This heavy-duty machine arrived in Houston last month and it is already working on the project site very successfully.

Project Background And Customer Application In The USA
The USA customer has a new government project in a busy city center. They must lay high-voltage power cables and large gas pipes under a wide highway and a local river. Standard digging methods are impossible because they cannot stop the traffic or destroy the green trees. Therefore, they need an efficient underground horizontal boring machine to finish the job quickly.
The total drilling distance for this project is 250 meters, and the underground soil contains hard clay and small rocks. The customer chose our YG-320 model because it has a 160KW engine and a strong motor system. They used our machine to drill a pilot hole first, and then they expanded the hole step by step using different reamers. The machine worked smoothly even when it met the hard rock layer under the ground.
Our customer gave us excellent feedback after using the machine for two weeks. They told our engineers that the machine is very stable. The mud pump provides a strong flow up to 320 Liters per minute, which cleans the drilling hole perfectly. The operators also like the comfortable cabin and simple control buttons. The project manager said our equipment saved them 35% of time compared to their old drilling methods.

Why USA Customer Chooses YG HDD Boring Machine
American customers have very strict standards for construction equipment. They choose our high-quality hdd boring machine for several key reasons:
- Premium Engine Power: We use top-brand engines with 140KW or 160KW power. This gives enough force to face complex ground conditions in North America.
- Excellent Push and Pull Force: Our machines use advanced cylinder or motor systems. For example, the YG-320 model provides 320KN force, which can pull heavy pipes easily.
- Compact and Strong Design: The steel body is very strong but the size is reasonable. The size of YG-320 is 7100 by 2250 by 2450 millimeters, which is easy to load onto a standard trailer.
- Perfect Safety Features: We install warning lights and emergency stop buttons to protect the workers on site.

How to Select the Right HDD Rig for Your Project
Choosing the correct machine depends on your local underground conditions and the size of the target pipes. To help you make the right choice, you should evaluate several key elements before purchasing:
- Check the Maximum Reaming Hole Diameter: If your project needs to pull large gas pipes, you must check the reaming size. For smaller pipes under Φ600mm, our YG-160A or YG-180 models are very efficient. If your target pipe diameter is larger, you should choose the YG-320 model because it supports a maximum reaming diameter of Φ800mm.
- Evaluate the Total Drilling Distance: Longer drilling projects require higher push and pull forces to handle heavy friction. Small projects can use a 160KN machine, but heavy-duty long-distance projects need a 320KN system to guarantee project safety.
- Know Your Local Soil Types: Hard soil and rock layers need more powerhead torque and stronger mudflow to wash out underground debris. Models like YG-280 and YG-320 offer a maximum mudflow of 320 Liters per minute and higher torque, which can easily drill through mixed soil conditions.
