Overview

The JTQZ-300-1 is a heavy-duty, high-capacity pneumatic crawler drill rig engineered for extreme deep-well drilling applications. Built to withstand rugged field environments, it combines a powerful engine system, advanced pneumatic technology, and exceptional load capacity to deliver uncompromising performance in large-scale agricultural, municipal, and remote industrial projects. As a core addition to our product lineup, the JTQZ-300-1 sets a new standard for efficiency and durability in 300-meter water well construction.

Core Design & Performance Highlights

1. Maximum Power & Penetration Force

Powered by an 85kW high-torque engine and equipped with a medium and high wind pressure system, the JTQZ-300-1 delivers industry-leading drilling force. With a swing torque range of 5700–7500 N.m and air consumption capacity of 17–36 m³/min, this rig excels in dense geological formations, ensuring rapid progress even in hard rock, gravel, and compacted sand layers. Its optimized efficiency (15–35 m/h) drastically reduces project timelines for large-scale drilling campaigns.

2. Superior Stability & Terrain Adaptability

Featuring a robust crawler chassis and a 1.4m high-leg stroke, the JTQZ-300-1 ensures exceptional stability on uneven construction sites and mountainous terrains. It effortlessly navigates slopes up to 30° and can traverse remote work sites with reliable mobility. The 18T rig lifting force and 2T winch hoisting force provide unmatched control during deep well construction, ensuring safe and precise handling of drill pipes even at maximum depths.

3. High-Speed Operational Efficiency

Designed for productivity, the rig boasts a fast feeding speed of 40 m/min and a rapid rise speed of 22 m/min. These industry-leading speeds minimize non-productive time, allowing crews to maximize daily footage rates. The 3.3m one-time advance length streamlines rod configuration, reducing manual labor and accelerating the drilling cycle to meet tight project deadlines.

4. Field-Proven Durability & Mobility

With a heavy-duty construction and a compact yet stable dimension of 4100×2000×2260 mm, the JTQZ-300-1 balances brute strength with practical transportability. Its 6.8T weight distribution ensures stability during operation, while the crawler design guarantees reliable performance in diverse weather conditions. Customizable drill pipe options (1.5m/2.0m/3.0m lengths) and a wide hole diameter range (140-325mm) make it a versatile solution for various well depths and sizes.
