Jinke JK860 Crawler DTH Drilling Rig for Hard Rock Water Wells
Hard rock water wells are a different job from drilling in soil: you need a DTH hammer, enough air, and a rig that can move between boreholes without a truck and crane crew. The JK860 crawler does exactly that. It drills 115-178mm holes and walks itself around the site on steel tracks.

Working Notes
- Match the compressor to the job: a 16-22 m3/min unit at 1.0-2.5 MPa drives 4-inch and 5-inch hammers for the 115-178mm range.
- Independent track drives let the operator counter-rotate and turn on narrow site roads.
- The wet dust collection system keeps the drill point and the crew cleaner - worth it on village sites and near buildings.
Water well depth depends on the hammer, pipe and compressor you run. Tell us your target depth and rock type; we will recommend the matching setup, including deeper mast and pipe configurations.
