The Comacchio GEO602HT Multipurpose Rotary Drilling Rig.
The GEO602HT is a compact, yet very powerful and hugely capable rotary rig capable of forming geotechnical, rotary cored or rotary open boreholes to depths in excess of 250m.
The GEO602HT rotary drilling rig is transported to site with our in-house LGV transport truck, this truck also carries all in-hole equipment as well as auxiliary equipment such as compressors and mud recycling equipment. The rig is supported by an Iveco 7t van and operates many systems, the capabilities of which are outlined below.
The rig can provide continuous cored sample recovery via dynamic sampling and rotary coring either conventionally with T6-116 or T6-146, or with wire-line in the form of Geobor-S. The latter of which allows boreholes to be cored to greater depths, in very efficient timeframes. It can also efficiently drill rotary open holes with the use of PCD and tri-cone NC bits. All systems are supported by either the on-board clean water mist pump, or the triplex 300L/min mud pump.
With a rotary head capable of high speed, low torque (up to 980rpm!) as well as high torque with low speed the Comacchio GEO602HT is also a highly capable hollow stem auger rig. Other systems include overburden casing and wireline coring. Flushing mediums include mud/water recirculation via the on board 300l/min mud pump, or air flush via an auxiliary compressor.
