The JTQZ500 is a heavy-duty pneumatic water well drilling rig designed for 500m ultra-deep drilling, ideal for domestic water wells, agricultural irrigation wells, geothermal wells and industrial mining water supply projects. Built with imported hydraulic core parts, dual-motor power head and professional crawler chassis, it excels in mountainous, rocky and complex stratum areas with 140-350mm adjustable borehole diameter, delivering high-efficiency, stable and durable performance for large-scale water well construction.

Core Advantages & Technical Highlights

1. 500m Ultra-Deep Drilling & High Efficiency

Supports Φ102/Φ108/Φ114mm drill pipes (1.5/2/3/6m lengths) and 6.6m one-time advance length, cutting rod handling time. 7500-10000N·m swing torque, 45-130rpm adjustable speed and 15-35m/h penetration efficiency, matched with medium and high air 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. Imported Hydraulics & High-Performance Power

Equipped with **Italian imported hydraulic oil pumps** (parallel gearbox design, independent power distribution) and integrated dual-motor power head for super torque and low maintenance. Powered by 118kW Yuchai/Cummins turbocharged diesel engine, it provides continuous, reliable power for ultra-deep field drilling.

3. Professional Chassis & Strong Cross-Terrain Mobility

Adopts custom professional drilling rig chassis with wide track plates (large load, low road damage) and new-type travel motor/reducer for long service life. 30° maximum gradeability, 2.5km/h travel speed, 2.85m loading width and 6150×2200×2600mm dimensions enable easy transportation and quick deployment in rugged mountainous/remote areas.

4. Enhanced Lifting & Safe, Durable Design

26T high rig lifting force and 2T winch hoisting force via composite large arm with double oil cylinder lift; lifting arm limit device protects oil cylinders for safe operation. All hydraulic oil pipes with thickened protective sleeves extend service life; 1.6m high leg stroke ensures stable leveling on uneven ground for precise drilling.

5. Dual Cooling & Dual Working Systems

Independent hydraulic oil cooling + air cooling dual system prevents overheating, prolongs engine/hydraulic component life for 24/7 continuous operation. Supports air power system (air compressor) and mud pump system dual configurations, customizable for different strata to realize one rig for multiple uses.

6. Industrial-Grade Durability & Low Maintenance

Heavy-duty welding and integrated forming for high overall rigidity, adapting to harsh field environments. Advanced hydraulic system with simple maintenance and low fault rate; brand/imported core parts reduce replacement frequency, lowering overall project operation costs.
