Product Parameter

The pneumatic drilling rig is a lightweight, efficient, and versatile drilling equipment mainly used for industrial and civil well drilling, as well as geothermal drilling. It features a compact structure, fast drilling, flexible mobility, and wide applicability, especially suitable for water extraction in mountainous and rocky terrains. This drill rig can perform drilling in various geological conditions, utilizing advanced hydraulic technology, large torque hydraulic motor for rotation, and a large cylinder diameter hydraulic cylinder for propulsion. A well-known multi-cylinder engine provides power for the hydraulic system, with a two-stage air filter and air compressor intake design to extend the diesel engine’s lifespan. The unique pump group design facilitates maintenance and reduces repair costs. The centrally controlled hydraulic console makes operation convenient. This series of drills adopts an excavator crawler chassis with strong off-road performance. The independent modular design allows the drill rig to be mounted on a truck, enhancing its maneuverability. Two-speed rotation and propulsion speeds meet different drilling needs in soil and rock layers. The combination positioning device can be adjusted and replaced according to different types of drill rods and impactors, ensuring accurate and reliable positioning. The winch mechanism facilitates the lifting of drill rods and impactors, reducing labor intensity.
