1. Capable of drilling up to 260 meters deep using pneumatic percussive drilling technology; it offers high drilling speeds in hard rock formations and is suitable for well-drilling operations across various rock and soil types. 2. Features a crawler chassis design with excellent off-road and climbing capabilities, ensuring flexible mobility and easy positioning at complex worksites such as farmlands and mountainous terrain. 3. Equipped with a fully hydraulic control system and an intuitive control panel; delivers high rotary torque and stable drilling performance, with compatibility for casing-advancing tools to handle formations prone to borehole collapse. 4. Boasts a compact structure that integrates rod lifting with the drill pipe handling mechanism, facilitating convenient loading and unloading of drill pipes and significantly shortening the construction cycle per borehole. 5. Powered by a stable, reliable system and paired with a down-the-hole (DTH) hammer, it supports a wide range of borehole diameters, making it ideal for constructing agricultural irrigation wells, domestic drinking water wells, and small-scale engineering dewatering wells.

Product Description： This 260-meter crawler-mounted pneumatic water well drilling rig utilizes the down-the-hole (DTH) pneumatic impact drilling principle and offers a maximum drilling depth of 260 meters. It features a crawler undercarriage for autonomous mobility on-site, making it suitable for complex terrains such as mountainous, hilly, and remote areas. The unit employs full hydraulic control and delivers powerful performance with exceptional efficiency in hard rock drilling; it also supports casing-while-drilling operations to prevent borehole collapse. Widely used for projects such as rural drinking water wells, agricultural irrigation wells, and shallow geological exploration, the rig is easy to assemble, disassemble, and maintain, serving as a highly efficient solution for medium-to-deep water well construction.
Product Features： 1. Utilizes pneumatic down-the-hole (DTH) impact drilling, offering powerful hard-rock breaking capabilities and high efficiency at depths up to 260 meters; it is resistant to drill jamming and excels in hard formations such as granite and limestone. 2. Compatible with various drill bit sizes for multi-purpose functionality; it can drill domestic drinking water wells and agricultural irrigation wells, while also meeting the requirements for small-scale engineering exploration boreholes. 3. Features a reinforced drill rod design with excellent torsional and bending resistance, ensuring high stability during deep-hole drilling, maintaining borehole verticality, and delivering high-quality well completion. 4. Equipped with centralized lubrication and protective structures; key components are dust-proof and wear-resistant, resulting in a low failure rate under harsh field conditions and simplifying routine maintenance. 5. Integrates an automatic drill rod unloading system, reducing manual labor intensity and operational risks while enhancing on-site safety.
