Description

The GREENTECH DTHR 300 is a versatile and robust truck-mounted DTH cum Rotary Drilling Rig designed for efficient and high-performance drilling operations. Capable of drilling up to 300 meters, this rig supports both Down-the-Hole (DTH) and Rotary Drilling methods.

Engineered with a box-type structure and powerful hydraulic operations, the rig ensures excellent rod handling, superior torque, and smooth pull-up/pull-down functions through a hydraulic cylinder and wire rope mechanism. Power is drawn directly from the truck engine via a transfer gearbox, ensuring seamless and reliable performance in varied terrains and formations.

We also offer optional attachments such as a welding generator, mud pump, GPS system, auto rod charger, and more to enhance functionality as per customer requirements.
