Geothermal drilling rigs

Geothermal Drilling Rig model GM840-DD with double rotary drive

Geothermal drilling rig - Geo-trac series - «Geo-Max» model GM840-DD with double rotary drive

High-performance, self-propelled geothermal / water well drilling rig featuring a Double Rotary Drive, the Geo-Max 840 DDOpening this files requires PDF.

The main advantages of the Geo-Max rig is its enhanced pullback capacity, extreme maneuverability, Double Rotary Head, designed specifically for Geothermal overburden drilling and our unique Casing and Rod Handling System.

 

 

 

Some important features include:

  1. Geothermal drilling rig Rotary Drive:  Double head EURODRILL models DH1400 or DH1900; Integrated dual-head designed specifically for Geothermal overburden drilling, where both, Casing and Drilling Rod operate at the same time. The 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.
  2. Robot arm, equipped with double clamps to simultaneously deliver the casing and the inner rod assembly to and from the rod feeder (feeding and discharging). This reduces the operating time, greatly increasing the efficiency and decreasing cost.
  3. Our unique hydraulic Dual Pipe Rack is capable of vertically storing 10ft long pipes. The primary Pipe Rack stores casing and inner rod assemblies (up to 150 ft) and the secondary Pipe Rack stores additional inner rods (up to 400 ft). Both pipe racks are attached to a hydraulic actuator, which allows the racks to be raised for drilling and lowered for transportation.

Our Geo- class drilling rigs are designed with the end user and their budget in mind.

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.
