Pneumatic Drill Rig GMH-500S

This series of water well drilling rigs is a lightweight, efficient, and multifunctional drilling equipment mainly used for industrial and civil well drilling, as well as geothermal drilling. It features a compact structure, fast drilling speed, and flexible mobility, making it especially suitable for water extraction in mountainous and rocky terrains. This rig performs reliably under diverse geological conditions by adopting advanced hydraulic technology, a high-torque rotation motor, and a large-diameter hydraulic propulsion cylinder. It uses a multi-cylinder diesel engine equipped with a two-stage air filter and air compressor intake system, extending service life. The unique pump group design simplifies maintenance, reduces downtime, and ensures stable operation. The centrally controlled hydraulic console provides efficient, user-friendly operation. Mounted on an excavator crawler chassis, this model provides strong off-road performance and excellent adaptability. The modular design allows it to be truck-mounted for easy transport. Two-speed rotation and propulsion systems meet drilling needs in both soil and rock formations. The adjustable positioning system ensures precision, while the integrated winch system improves lifting and impactor handling efficiency, significantly reducing labor intensity and improving productivity.
