The JTQZ700 is a heavy-duty air-water dual-use crawler pneumatic drilling rig engineered for 700m ultra-deep drilling, featuring patent composite boom, imported hydraulic components and reinforced crawler chassis. Ideal for deep water well drilling, hydrological exploration, geothermal development and industrial mining water supply projects, it delivers powerful power, high efficiency and stable performance in complex strata and harsh field conditions.

Core Advantages

1. 700m Ultra-Deep Drilling & High Efficiency

140-350mm borehole diameter, Φ102/Φ108/Φ114mm drill pipes (1.5/2/3/6m lengths) and 6.6m one-time advance length cut rod handling time. 8500-11000N·m swing torque, 45-140rpm adjustable rotation speed and 15-35m/h penetration efficiency, matched with medium & high pressure impactors (1.7-3.5MPa working pressure, 17-42m³/min air consumption), ensure smooth drilling through hard rock, mud and sand strata at full depth.

2. Powerful & Durable Core Configuration

Powered by 132kW Cummins six-cylinder turbocharged engine for strong, long-lasting output; equipped with Italian imported 3-unit oil pump with parallel drive design, realizing scientific power distribution and stable hydraulic performance. Configured with foam pump, multi-functional generator and front leg swing arm cylinder, meeting diverse on-site construction needs.

3. Patent Structural Design & High Safety

Patent composite boom with double-cylinder lifting and reinforced tower frame for 28T high lifting force, easily handling heavy drill strings at 700m depth. Baffle on the main boom protects oil cylinders from damage; 1.7m high leg stroke ensures stable leveling on uneven ground, and 2T winch hoisting force supports auxiliary construction operations, maximizing operational safety.

4. Reinforced Crawler Chassis & Strong Mobility

Reinforced steel crawler with large chassis, wide track plates and heavy load-bearing capacity, adapting to rugged mountainous, rocky and muddy terrain. 30° maximum gradeability, 2.5km/h travel speed, 2.95m loading width and 6200×2200×2950mm dimensions enable easy transportation and quick on-site deployment for remote deep drilling projects.

5. Dual Cooling & Dual Working Systems

Hydraulic oil temperature cooling + air cooling dual heat dissipation system effectively controls temperature, prevents overheating and prolongs engine and component service life for 24/7 continuous operation. Supports air power system (air compressor)** and **mud pump system** dual configurations, realizing air-water dual-use and adapting to different stratum drilling requirements with one rig for multiple uses.

6. Easy Maintenance & Low Operation Cost

Unique hydraulic system design with simple structure and parallel drive, reducing fault rate and maintenance difficulty. All core components adopt brand and imported quality, with long service life and low replacement frequency; reinforced overall structure adapts to harsh field environments, lowering the overall project operation cost.
