XT400MP

 

The XT400MP is an ultra modern all-hydraulic Top Head Drive drilling rig with 1.7 metres of feed travel and 3 metre rod hauling capacity.

The rig is equipped with a Rineer Rotation Head which was developed from the oil field and develops an almost flat torque curve from start up to maximum rpm. The drill head hinges to one side, for clear access to the drill string for either rod hauling or core retrieval.
