HQZ-320L Pneumatic Drill Rig

Drilling depth: 320m
Drilling diameter: 130-325mm
Main motor power: 85Kw
The HQZ-320L Pneumatic Drill Rig is a high-efficiency crawler-mounted drilling machine developed for professional drilling operations such as water well construction, geological exploration, geothermal drilling, mining exploration, and engineering investigation. It combines advanced pneumatic DTH drilling technology with a reliable hydraulic rotary system to provide excellent drilling speed, strong rock penetration, and stable performance.

Designed for medium-depth drilling applications, the HQZ-320L Pneumatic Drill Rig delivers outstanding performance in different geological environments. The machine uses compressed air to power the down-the-hole hammer, transferring impact energy directly to the drill bit. This allows the rig to efficiently break hard rock formations while maintaining stable drilling progress.

Compared with conventional drilling machines, the HQZ-320L provides advantages such as faster penetration, better hard rock adaptability, lower drilling resistance, and improved operational efficiency.

The crawler-mounted structure gives the HQZ-320L excellent mobility and stability. It can easily move and operate in mountains, construction areas, mining fields, farmland, and remote locations where working conditions are challenging.
