Geothermal Drill Rig Geo-Max

Geothermal Drill Rig Geo-Max

The MAX series GM840-DD is a state-of-the-art geothermal drilling rig, has higher power characteristics, depth capabilities and features a high-tech electronic control system with advanced operational power management subsystems, allowing for higher operational efficiency and reduced drilling cost.The main advantages of GM840 are its extreme maneuverability, pullback capacity of 42000 lbs (19050 kg), hydraulic power of 220 HP, Double head designed specifically for Geothermal overburden drilling and a unique rod handling system. These features enable GM840 to easily access almost any type of difficult terrain, and give it enough power to drill in every type of mixed ground conditions (overburden / hard rock).

* Required Fields




Rotary Drive: Double head EURODRILL model DH1900; Integrated dual-head designed specifically for Geothermal overburden drilling, where both, Casing and Drilling Rod operate at the same time. Counter-clockwise operation of the Casing and Drilling Rod Gears significantly increases drilling efficiency and precision, preventing an inadvertent release of rod and casing during the pipe feeding and discharging.
Robot arm, equipped with double clamps to simultaneously deliver the casing and inner rod assembly to the rod feeder and back (feeding and discharging). This reduces the operating time and greatly increases efficiency, since this operation can be done while drilling.
GM840 features our uniquely designed hydraulic pipe rack, capable of vertically storing 10ft long pipes. The rack is attached to a hydraulic actuator, allowing it to be raised for drilling and lowered for transportation. First Pipe Rack stores casing and inner rod assemblies (up to 150 ft). Second Pipe Rack stores additional inner rods (up to 400 ft).
