1. Features a maximum drilling depth of 500 meters and a compatible hole diameter range of Φ140–Φ350 mm; utilizes a pneumatic Down-The-Hole (DTH) impact drilling method, relying on high-pressure air for rock fragmentation and cuttings discharge. 2. Equipped with a crawler undercarriage and four hydraulic leveling outriggers; features low ground pressure, enabling autonomous movement across mountainous, muddy, or uneven terrain, as well as rapid positioning and leveling. 3. Incorporates a fully hydraulic control system, a high-torque hydraulic power head, and a long-stroke feed rail; includes an integrated hydraulic rod-handling device to automate the loading and unloading of drill rods. 4. Built with high-strength rods and a reinforced frame structure; compatible with various specifications of drill rods, DTH hammers, and drill bits, and can be paired with suitable air compressors for complete operational setups.

Product Description ： The YGQZ-500 well drilling rig utilizes a pneumatic down-the-hole (DTH) impact drilling process. It features a maximum drilling depth of 500 meters and a borehole diameter range of 140–350 mm. Powered by a diesel engine and mounted on a hydraulic crawler chassis, the unit is equipped with a high-power DTH impactor. It is specifically designed for deep-well construction in challenging mountainous formations—such as hard rock, granite, and limestone—and is suitable for drilling domestic drinking water wells, agricultural irrigation wells, industrial deep wells, and shallow geothermal boreholes. The rig relies on compressed air to drive the impact mechanism for rock fragmentation and to clear cuttings, eliminating the need for large volumes of water or drilling mud, making it ideal for drilling operations in arid or water-scarce regions.
Product Features： 1. High drilling efficiency in hard rock; drilling speeds in hard formations—such as granite and limestone—far exceed those of traditional rotary water-flush drills, resulting in shorter project timelines. 2. Pneumatic dry cuttings removal eliminates the need for large quantities of water, making the rig ideal for drilling operations in arid, water-scarce mountainous regions or remote sites lacking water sources. 3. Highly mobile with self-propelled crawler tracks; it requires no trailers or cranes for transport, facilitates easy repositioning on-site, and reduces equipment relocation costs. 4. Centralized, simple controls featuring integrated hydraulic joystick operation and safety protection structures, thereby reducing operator fatigue. 5. Versatile multi-purpose design; compatible with interchangeable drilling tools to handle various projects, including water well drilling, geological exploration holes, and shallow geothermal boreholes.
