1. Rated drilling depth of 700 meters; utilizes the pneumatic Down-The-Hole (DTH) impact method with a borehole diameter range of 100–254 mm. It is compatible with various drill rod specifications and medium-to-high air pressure DTH hammers, and supports casing-while-drilling techniques for stabilizing fractured or collapsing formations. 2. Features a fully hydraulic integrated control system with adjustable power head torque. Equipped with a long-stroke feed rail and an automatic hydraulic rod handling system, it offers a high level of automation for rod connection and disconnection, thereby reducing manual labor. 3. Built on a reinforced engineering-grade crawler chassis with four independent hydraulic outriggers and a heavy-duty folding drill mast. The machine features an optimized center of gravity and excellent gradeability; it allows for rapid positioning and leveling, and can be relocated between sites without dismantling the mast.

Product Description ： The YGQZ-700 crawler-mounted pneumatic water well drilling rig is designed for medium-to-deep down-the-hole (DTH) percussion drilling, offering a maximum drilling depth of 700 meters and a hole diameter range of 100–254 mm. Powered by a high-output diesel engine and featuring a fully hydraulic drive system, the rig utilizes an external air compressor to supply high-pressure air that drives the DTH hammer to crush rock formations; the compressed air simultaneously conveys rock cuttings to the surface for dry discharge. It is capable of efficiently drilling through granite, dolomite, and limestone, as well as fractured bedrock with alternating hard and soft layers.
Product Features: 1. High stability for deep-hole operations: The frame and drill tower feature a reinforced design capable of withstanding the impact of the self-weight of 700 meters of drill rods; this effectively suppresses drilling vibration and improves borehole verticality. 2. Dry pneumatic cuttings removal: Drilling operations do not require large water supplies or the excavation of mud pits, allowing for direct operation in arid, water-scarce regions and reducing initial site setup costs. 3. Efficient drill rod handling: A long-stroke carriage combined with a hydraulic rod-unloading mechanism minimizes auxiliary time spent on frequent rod tripping, accelerates overall well completion, and boosts project profitability. 4. Highly integrated unit: The foldable drill tower allows for convenient setup and stowage, while the crawler-mounted design ensures flexible on-site mobility; the unit can be transported via standard trucks, eliminating the need for expensive heavy-duty lifting equipment. 5. Strong adaptability: Pre-installed interfaces allow for the addition of a foam injection system when encountering clay interlayers, mitigating issues like bit clogging and cuttings accumulation, thereby expanding the range of drillable geological formations.
