The main advantages of GRC4 are its simplicity (fully hydraulic operations); extreme maneuverability; pullback capacity of 48000 lbs (21 770 kg); hydraulic power of 156 HP; multipurpose hollow spindle rotary drive with variable/reversible hydraulic motor and automatic constant rotation power control. These features enable GRC4 to easily access almost any type of difficult terrain, and give it enough power to drill in any type of mixed hard formations.

Some important features include:
1) 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.
2) 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.
3) 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).
GM840 is designed with the end user in mind. You will be able to benefit from its unique features optimized for high performance, efficiency and reliability in any operational environment.
]]>1) The GD840 now features a new motor with a pull back force of 40 000lbs at start and 48 000lbs after 2-3 second of traveling.
2) Robot Arm features double lifting capacity, handling pipes and casings with a minimum reach of 15’.
3) Foam supply for water mist is now automatic and operated by the remote control.
4) A mud pump can now be optionally added and can be used when drilling without a compressor which provides fuel savings of over 100$/hrs, plus the facility to inject the bentonite without any other resources.
