The JTQZ400 is a professional **pneumatic water well drilling rig** engineered for 400m deep drilling, ideal for domestic water wells, agricultural irrigation wells and geothermal wells—especially for water extraction projects in mountainous and rocky areas. Boasting strong cross-terrain performance, multi-stratum adaptability and dual-system compatibility, it delivers efficient and stable drilling in rock, mud and sand formations, with a maximum borehole diameter of 325mm to meet diverse on-site water well construction needs.

Core Competitive Advantages

1. 400m Deep Drilling & High Penetration Efficiency

Supports 140-325mm borehole diameters and Φ89/Φ102mm drill pipes (1.5/2.0/3.0/6.0m optional lengths), with a 6.6m one-time advance length that reduces rod handling time. 15-35m/h penetration efficiency and 6500-9000N·m swing torque (66-135rpm rotation speed) ensure fast and smooth drilling even in hard rock formations.

2. All-Stratum Adaptability & Professional Pneumatic System

Equipped with medium and high air pressure series hammers, matching 1.7-3.4MPa working air pressure and 17-36m³/min air consumption. The high-torque hydraulic motor power head and two-gear rotation/feeding speed adapt to rock, mud and sand strata seamlessly, realizing one rig for multi-scenario drilling.

3. **Super Cross-Terrain Mobility & Flexible Installation**

Adopts excavator crawler chassis with 30° maximum gradeability and 2.5km/h travel speed, delivering excellent off-road performance in mountainous and rugged terrain. Optional truck-mounted installation for enhanced mobility; 2.7m loading width and 6000×2000×2550mm dimensions simplify transportation and on-site deployment.

4. Reliable Power & Hydraulic Control

Powered by Yuchai 92kW diesel engine with two-stage air filtration system, ensuring stable power output and long service life—supports direct connection to air compressor for clean air supply. The hydraulic control system features large-diameter hydraulic cylinders, with 24T rig lifting force, 2T winch hoisting force, 18m/min fast lifting speed and 33m/min fast feeding speed for efficient operation.

5. Humanized Design & Dual-System Compatibility

Unique convex block structure and centralized control system for easy operation and daily maintenance, reducing operator fatigue and training time. 1.6m high leg stroke ensures stable drilling on uneven ground; compatible with **air power system (matching air compressor)** and **mud pump system (matching mud pump)** for customized configuration based on stratum conditions.
