Pneumatic Drill Rig GMH-450S

This series of pneumatic water well drilling rigs is a lightweight, efficient, and versatile 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 adaptability, especially suitable for water extraction in mountainous and rocky terrains. These rigs perform efficiently under various geological conditions using advanced hydraulic technology and high-torque motors for rotation, combined with a large hydraulic propulsion cylinder. The diesel engine adopts a multi-cylinder design with a two-stage air filter and air compressor intake to prolong engine life. A unique pump group design simplifies maintenance and reduces downtime, while the centralized hydraulic control console ensures easier operation. Mounted on an excavator crawler chassis, this series offers strong off-road performance. The modular design allows the rig to be truck-mounted for greater mobility. Dual-speed rotation and propulsion systems suit different soil and rock formations. The adjustable positioning system ensures accurate drilling, while the integrated winch facilitates efficient lifting of drill rods and impactors, reducing labor intensity and enhancing productivity.
