Product Description ： This 350-meter crawler-mounted pneumatic water well drilling rig utilizes the down-the-hole (DTH) pneumatic impact drilling method, achieving a maximum drilling depth of 350 meters. Its crawler chassis offers excellent mobility, allowing it to navigate complex terrain in the field. The fully hydraulic control system ensures ease of operation, while the rig delivers high drilling speeds in hard rock and supports casing-while-drilling operations to prevent borehole collapse. Featuring a robust structure and easy maintenance, the rig is widely used for rural drinking water projects, agricultural irrigation wells, shallow geological exploration, and the construction of dewatering wells for small-scale engineering projects, making it a highly efficient solution for medium-to-deep well drilling.
Product Features： 1. Features a high-power pneumatic impact system with strong hard-rock breaking capabilities; ensures stability during 350-meter deep-hole operations and significantly reduces the time required to drill through rock formations. 2. Equipped with a reinforced drill rod featuring high bending and torsional strength; ensures borehole verticality during deep-hole drilling and improves overall well construction quality. 3. Includes an integrated hydraulic rod-unloading mechanism for automatic joint disconnection; minimizes manual handling, reduces labor intensity, and enhances operational safety. 4. Core components feature dust-proof protection, ensuring durability and wear resistance in dusty field environments; offers low failure rates and easy maintenance. 5. Boasts a compact overall layout allowing for rapid assembly and disassembly of drilling tools; offers flexible site mobility and multi-purpose functionality to meet various well-drilling requirements across different borehole diameters.
