Overview

The JTQZ-300-3 is a purpose-built pneumatic crawler rig designed for 300m deep water well construction and demanding groundwater extraction projects. Engineered for durability and operational simplicity, it caters to drilling contractors, agricultural enterprises, and municipal water authorities worldwide, delivering consistent performance across diverse geological conditions.

Core Strengths & Design Philosophy

Optimized Drilling Productivity: Powered by a high-efficiency power system and medium-high wind pressure hammer, it delivers stable penetration rates of 15–35m/h. The 3.3m one-time advance length and fast cycle speeds (40m/min feeding, 22m/min rising) cut down on non-drilling time, boosting daily footage without sacrificing precision.

Heavy-Duty Load Handling: With 18T rig lifting force and 2T winch capacity, it safely manages heavy drill strings at maximum depth. The 5700–7500N·m swing torque range ensures reliable rotation in compacted sand, gravel, and soft rock formations, while adjustable air pressure (1.7–3.0MPa) adapts to site-specific geology.

Field-Proven Mobility & Stability: A 30° maximum gradeability and 1.4m high-leg stroke let it operate confidently on sloped, uneven terrain. Its crawler chassis and 2.6m loading width simplify transport between remote job sites, while the reinforced 6.8T structure ensures long-term durability under continuous heavy use.

Flexible Configuration: Customizable drill pipe lengths (1.5/2.0/3.0m) and hole diameters (140–325mm) make it adaptable to everything from small community wells to large-scale agricultural irrigation projects, aligning with the unique needs of global clients.
