Overview

The JTQZ-350 is a heavy-duty pneumatic crawler rig purpose-built for 350-meter deep water well construction and large-scale groundwater extraction projects. Powered by a reliable Yuchai engine, it combines industry-leading penetration efficiency, robust load capacity, and terrain adaptability to serve the most demanding drilling needs in agricultural irrigation, municipal water supply, remote industrial operations, and hydrological monitoring worldwide.

Core Performance Advantages

High-Power Pneumatic Drilling System: Driven by a 91kW Yuchai engine and paired with a medium-high wind pressure hammer, the JTQZ-350 delivers a swing torque of 6200–8500N·m and air consumption of 17–36m³/min. This setup ensures smooth penetration through hard rock, gravel, and compacted sand layers, with a penetration efficiency of 15–35m/h to keep large-scale projects on schedule.

Extended One-Time Advance & Fast Cycle Speeds: With a 6.6m one-time advance length, the rig drastically reduces rod-handling frequency and non-productive downtime. Combined with a 33m/min fast feeding speed and 18m/min rapid rise speed, it maximizes daily drilling output while maintaining precision at full depth.

Superior Load Handling & Stability: Boasting a 22T rig lifting force and 2T winch hoisting capacity, the JTQZ-350 safely manages heavy drill strings at 350m depth. Its 1.4m high-leg stroke and 30° maximum gradeability ensure stable operation on slopes and uneven terrain, while the reinforced 8.6T structure guarantees long-term durability under continuous heavy use.

Flexible Configuration & Transportability: Customizable drill pipe lengths (1.5/2.0/3.0/6.0m) and hole diameters (140–325mm) adapt to diverse geological and project requirements. The crawler chassis and 2.7m loading width simplify transport between remote job sites, making it ideal for global field operations.
