Rl400s 400m Depth Stable & High Efficiency Diesel Powered Fully Hydraulic Crawler-Mounted Rotary Water-Air Dual Purpose Borehole Drilling Machine

Product Description

Crawler-type water well drilling machine

  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).
  Backed by rich experience, strict quality control and full after-sales service, we provide cost-effective, flexible solutions—whether crawler or customized truck-mounted.
