Product description
Christensen CT20 has a drilling depth capacity of 2,450 meters. The rig comes truck-mounted or crawler-mounted, which means it can be easily transported. Despite its power, the Christensen CT20 is easy to run thanks to an intuitive control panel which makes it easy to operate the numerous functions. The work environment around the Christensen CT20 has also been a focus throughout the development process; for example, the Tier 4 version of this rig is equipped with a sound reducing engine canopy.
