Pneumatic Drill Rig GMH-350S

This series of water well drilling rigs 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. These drilling rigs can perform well in various geological conditions, utilizing advanced hydraulic technology, large-torque hydraulic motors for rotation, and large-cylinder hydraulic propulsion systems. The multi-cylinder diesel engine provides powerful hydraulic output, equipped with a two-stage air filter and air compressor intake to extend engine service life. The unique pump group design simplifies maintenance and reduces repair costs, while the centralized hydraulic control console ensures convenient operation. Mounted on an excavator crawler chassis with strong off-road capability, this series offers modular structure and can be truck-mounted for flexible transport. Dual-speed rotation and propulsion settings meet different drilling requirements for soil and rock layers. The positioning device can be adjusted and replaced for various drill rods and impactors, ensuring high drilling accuracy and efficiency. The integrated winch system allows easy lifting of drill rods and impactors, reducing labor intensity and improving productivity.
