Product Description : The YGQZ-350 borehole drilling machine features a high-efficiency down-the-hole (DTH) impact system and offers a maximum drilling depth of 350 meters. It is equipped with a wide-track undercarriage for superior off-road mobility and an independent cooling module, supporting both vertical and inclined drilling operations. The machine boasts excellent high-temperature resistance and continuous operational capability, enabling it to handle complex and varied geological conditions. It is suitable for drilling drinking water wells (for humans and livestock), deep agricultural wells, foundation dewatering holes, and geological monitoring wells; it offers user-friendly controls and high reliability for extended field operations.
Product Features: 1. Optimized air circuit layout minimizes air pressure loss, ensures stable impactor power output, and reduces power attenuation during deep-hole drilling. 2. Integrated hydraulic outriggers enable rapid machine leveling, suppress rig oscillation, and enhance stability during deep-hole drilling. 3. A centralized control console equipped with pressure monitoring gauges allows for real-time tracking of down-hole conditions, facilitating the early detection of potential anomalies. 4. The machine features a lightweight design that maintains structural integrity while simplifying trailer transport and reducing shipping costs. 5. An optional dust collection system is available to suppress drilling dust and improve the working environment at the job site.
