1. Designed for a maximum drilling depth of 400 meters, the system features a high-flow pneumatic DTH (Down-The-Hole) impact mechanism that minimizes impact force attenuation in deep-hole operations, ensuring efficient penetration through thick rock strata. 2. Utilizes a high-strength, modular drill rod structure that allows for sectional disassembly and transport, meeting the structural integrity requirements for deep-well drilling in remote field environments. 3. Equipped with a high-torque hydraulic rotary head compatible with large-diameter drill rods; supports long-distance casing-advanced drilling to mitigate risks of borehole collapse in quicksand or fractured rock formations. 4. Features an integrated intelligent pressure monitoring assembly that tracks air and hydraulic pressure parameters in real-time, enabling operators to stay informed of downhole drilling conditions at all times.

Product Description ： The 400-meter crawler-mounted Borehole Drilling Rig is specifically designed for medium-to-deep hard-rock water wells, offering a maximum drilling depth of 400 meters. It features a high-strength sectional mast paired with a high-torque hydraulic power head, ensuring stable power output for deep-hole operations. An integrated pressure monitoring system tracks working conditions in real-time, and the rig supports casing-while-drilling operations in fractured formations.
Product Features： 1. Optimized, extended air supply piping minimizes pressure loss, ensuring the impactor delivers consistent impact force even during operations in 400-meter-deep wells. 2. Equipped with a hydraulic automatic locking mechanism, it ensures reliable locking during drill rod handling, reducing the risk of drill string loss in deep-hole operations and enhancing safety. 3. Features a heavy-duty hydraulic cooling system that effectively regulates oil temperature during prolonged, continuous deep-well operations, preventing system shutdowns caused by overheating. 4. The machine utilizes a welded frame made of thickened steel plate, offering superior vibration resistance and structural integrity; it resists deformation during long-term hard-rock impact drilling, resulting in a longer service life. 5. Includes reserved expansion ports for optional accessories—such as dust collection units and mud-assist systems—to meet diverse environmental standards and the demands of complex geological formations.
