Jinke JK860 Geothermal Drilling Rig
Geothermal and ground source heat projects do not need a one-off machine - they need a rig that drills the same reliable hole, over and over, for years. That is what the JK860 is on this job: a 1000m rotary rig with an 860mm table that handles both vertical production wells and large-diameter heat exchange boreholes.

Why Contractors Use It for Heat Exchange Work
- Consistent rotation and hoisting control keeps borehole walls clean for grouting and loop installation.
- Wide speed range suits both soft overburden (slow, high torque) and hard rock (faster rotation with tri-cone or DTH tooling).
- 1000m rating leaves headroom - you are not running the machine at its limit on a 300m project.
Tell us your loop field size and typical depth; we will suggest the drill pipe and mud pump setup that matches your formation.
