Drilling depth: 400m
Drilling diameter: 140-325mm
Main motor power: 92kw
The JTQZ-400 pneumatic water well drill rig is built for 400 m deep well drilling in municipal water supply, agricultural irrigation, industrial water projects and environmental monitoring. With a 92 kW engine, 24 t lifting force, 1.7-3.4 MPa working pressure and rotation speeds up to 135 rpm, it is designed for deeper boreholes, heavier drill strings and more demanding rock conditions.

1. Reaches 400 m Depth
With 1.7-3.4 MPa working air pressure, 17-36 m³/min air consumption and a 92 kW engine, the JTQZ-400 is equipped for deep groundwater drilling to 400 m. This makes it a strong fit for high-demand water well projects where shallower rigs start to lose efficiency.
2. 24 t Pullback Power
A 24 t rig lifting force combined with 33 m/min rapid rise speed gives the rig the strength to pull long, heavy drill strings from deep holes with less delay. That matters on deep well jobs where pipe handling speed directly affects daily output.
3. 92 kW Diesel Drive
The 92 kW power unit supports stronger drilling force than the smaller models in the series, while the 66-135 rpm rotation range gives operators more control across clay, gravel and harder rock layers. It is built for higher-load drilling rather than light-duty shallow work.
4. Fewer Rod Changes
A 6.6 m single push length and drill pipe options from 1.5 m to 6.0 m reduce the number of rod additions during deep drilling. Fewer connection cycles help save time, lower labor intensity and keep the rig moving efficiently on longer boreholes.
5. 1.6 m High Leg
The 1.6 m high leg stroke improves leveling range on rough ground, and together with 30° climbing ability and 2.5 km/h travel speed, the rig is easier to place on uneven water well sites. That gives crews better setup flexibility before drilling starts.
