1. Multi-process capability with high formation adaptability: Seamlessly switch between mud drilling, pneumatic DTH (down-the-hole) hammer drilling, and wireline coring modes. Capable of handling various strata—from soft soil and pebbles to hard rock—it eliminates the need for frequent rig changes, thereby reducing equipment procurement costs. 2. Powerful and stable performance with high torque and a wide speed range: Features a maximum torque of 9,800 N·m and a rotational speed range of 33–1,120 r/min. A 2,300 mm-long power head stroke ensures smooth drilling, minimizes the risk of drill bit jamming or overheating, and is equally effective for deep-hole coring and water well construction. 3. Crawler-mounted mobility and hydraulic outriggers for cost-efficient site transitions: The rubber-steel crawler tracks prevent damage to road surfaces and offer excellent off-road climbing capability. Four hydraulic outriggers enable automatic leveling and self-loading/unloading, eliminating the need for external cranes or manual labor and accelerating site setup.

Product Description： The YGDQ-280 is a multi-functional, crawler-mounted, top-drive drilling rig designed for both water-based (mud) and pneumatic (air) drilling. It supports multiple drilling methods, including mud-rotary drilling, pneumatic down-the-hole (DTH) hammer drilling, and NQ wireline coring. This rig effectively addresses common industry challenges: conventional pneumatic drills often face high resistance and difficulty in forming boreholes within loose soil layers, while standard water-based drills suffer from slow penetration rates and high consumable wear when operating in hard rock, gravel, or pebble formations. Featuring a mechanical top-drive rotary system combined with a hydraulic feed mechanism, the YGDQ-280 allows for seamless switching between drilling techniques, making it highly adaptable to various soil types and bedrock formations (ranging from F6 to F20 in hardness).
Product Features: 1. Rubber-steel crawler undercarriage: Offers a travel speed of 0–2 km/h and a climbing capacity of 25°–30°. It is surface-friendly, ensuring no damage to ground surfaces in municipal areas, orchards, or on paved roads, while providing excellent off-road mobility. 2. Four hydraulic high-reach outriggers: Allow for independent leveling, ensuring a stable setup during operation. The unit supports self-loading and unloading, eliminating the need for an external crane—thereby saving on lifting costs and facilitating operations at remote job sites. 3. Ergonomic design features: Comes standard with a drill rod rack for organized storage and easy access. An auxiliary rod-unloading cylinder is positioned at the front, simplifying the process of loosening drill rod connections and reducing physical strain on operators. 4. Reliable drive system: The hydraulic pump is connected directly to the power source via a universal joint, minimizing power transmission loss and ensuring robust performance during travel and climbing. Equipped with an automotive-style transmission and a hydraulic release bearing, it offers smooth gear shifting and a proven, durable design. 5. Diesel power configuration: Powered by a YN27 diesel engine with a rated output of 42 kW, providing ample power reserves. It is well-suited for integration with air compressors, supporting operating pressures of 10.5–24.6 bar and air consumption rates of 16–35 m³/min.
