1. Reaches 300 m Depth
An 85 kW engine works with 1.7-3.0 MPa air pressure and 17-36 m³/min air consumption to support stable drilling to 300 m. This output gives the rig the pneumatic power needed for deep groundwater projects in sand, gravel and hard rock.
2. Fewer Rod Changes
A 6.6 m single push length is the standout advantage of this model. Together with drill pipe options from 1.5 m to 6.0 m, it reduces rod handling time, shortens drilling cycles and helps crews keep productivity high on deep wells.
3. Up to 325 mm Holes
The 140-325 mm drilling range covers irrigation wells, municipal water supply, industrial boreholes and monitoring wells in one machine. Compatible 76 mm and 89 mm drill pipes give operators flexibility across different formations.
4. 18 t Lifting Force
With 18 t rig lifting force and 40 m/min rapid rise speed, the JTQZ-300-2 can pull heavy drill strings quickly from deep boreholes. That reduces retrieval time and lowers the risk of delays when working at full depth.
5. Built for Rough Sites
A crawler chassis with 30° climbing ability, 2.5 km/h travel speed and 1.4 m high-leg stroke keeps the rig moving and stable on slopes, muddy ground and uneven terrain. The 8 t operating weight also adds confidence in demanding deep-well conditions.
