The MC 20 A is the latest addition to the MC line, developed with a particular focus on projects involving the installation of anchors / tiebacks with casings using double head drilling systems. The MC 20 A is a particularly compact hydraulic drilling rig in the 20-tonnes weight class. A major feature of this machine is the rods and casings carousel, allowing for the mechanized handling of the drilling equipment. The carousel can handle up to 9 pairs of rods / casings for a total of 30 m of double drill string length. The heavy-duty design of the MC 20 A is based on the robust oscillating undercarriage that adapts to ground irregularities and offers flexible positioning and enhanced stability. The machine is equipped with a new generation Cummins QSB6.7 engine, offering 209 kW power and complying with the most stringent EU Stage V / US EPA Tier 4 Final regulations. The powerful engine allows to run simultaneously a 200 l/min flushing pump and a dual head system. The dual system can be configured as rotary-rotary or rotary-drifter, providing up to 3200 daNm torque on the lower rotary head. A vast selection of single rotary heads and powerful hydraulic drifters are also available. Thanks to the powerful engine and the wide range of accessories, the MC 20 A can be customized according to the client’s needs. Thanks to the Comacchio proprietary all-in-one radio control system, allowing for the control of all rig functions, including rod handling, the entire work cycle can be performed by one person instead of two or three.
