Crawler High-Leg Pneumatic Hydraulic Borehole 350m Depth Water Well Drilling Rig Machine

Product Description

 

Product Description

Our company develops, produces and sells full hydraulic crawler-mounted water well drilling machines, ideal for water well construction in diverse geological conditions. With advanced full hydraulic transmission, they offer precise operation, strong power and stable drilling.

The crawler chassis ensures excellent terrain adaptability-performing well in mountains, muddy fields and remote areas where wheeled machines struggle. Our machines cover drilling depths from 180m to 3000m, meeting needs from small rural projects to large industrial deep-well tasks.

Notably, all crawler rigs can be modified to truck-mounted versions. This retains core hydraulic performance while boosting mobility, reducing relocation time and no need for extra transport equipment (e.g., cranes).
