High Performance in Demanding Conditions

With a rated torque of 65,000 Nm, the THD-280T delivers the rotational strength needed to drill through dense rock layers, hard-packed clay, gravel, and mixed ground. Its 2800 kN of thrust and pullback force ensures that long crossings—whether beneath rivers, highways, or densely built urban areas—are executed efficiently and with precision.

The two-stage variable rotation control system provides smooth power delivery and precise direction control, allowing operators to adapt easily to real-time drilling conditions. This makes the THD-280T ideal for directional boring tasks in oil and gas pipelines, power cable conduits, water supply lines, and fiber optic installations.

Smart Engineering for Operator Efficiency

Operator safety and control are at the core of the THD-280T design. The fully enclosed operator cabin is equipped with an intuitive control panel, digital monitoring instruments, and an ergonomic layout for long shifts. All operational data—such as torque, pressure, pullback force, and rotation speed—are displayed in real-time.

A hydraulic automatic rod loader is available as an option, reducing labor intensity and speeding up pipe handling. The 6-meter drill rod design further enhances efficiency by reducing rod change frequency and minimizing downtime.

Robust Structure and Reliable Components

The THD-280T features a durable rack-and-pinion drive system, offering superior resistance to wear and maintaining high positioning accuracy. The machine base is mounted on a reinforced steel track platform, enabling it to maneuver easily across varied terrain conditions, including muddy, rocky, and sloped construction sites.

The main spindle with a 76mm through-hole provides generous clearance for mud flow and tooling options. This allows for seamless integration with a wide range of downhole tools and fluid management systems. The rig is also compatible with industry-standard drill pipe threads and HDD accessories.

Integrated Mud and Circulation System

To support long-distance trenchless drilling, the THD-280T can be paired with a complete mud mixing and recycling system. These units are engineered to maintain consistent fluid pressure and remove cuttings efficiently, protecting the borehole walls and minimizing drilling resistance.

Advanced filtration systems help extend the service life of pumps and valves, while intelligent flow control reduces waste and environmental impact. For soft or collapsible formations, optional drilling additives and polymers can be integrated for added stability.

Applications Across Multiple Sectors

The THD-280T HDD rig is suited for a wide variety of trenchless applications, including:

• Municipal pipeline crossings
  (water, gas, sewage)

• Electrical and telecommunication conduits

• Oil & gas pipeline installations

• River and highway crossings

• Urban infrastructure expansion

• Industrial site connectivity

It is especially useful in projects requiring long-distance horizontal boring, high load capacity, or installations in sensitive or congested environments where open-cut excavation is not feasible.
