XT100MP Ultralight


The XT100MP-Ultralight is a full hydraulic Top Head Drive diamond core-drilling rig with 1.7 metre feed travel and 3 metre rod hauling capability.

The Rig is designed for Man-Portable Diamond Drilling and breaks down into only 10 components with the heaviest component weighing 110kg.

The rig is equipped with a hollow shaft Rineer Rotation Drill Head, which was originally developed for the oil field industry. The drill head hinges to one side, for clear access to the drill string.

Depending on the helicopter size the rig can be picked up as a single unit or split into two to fit the capabilities of say a Bell206 Jetranger. The total weight fully assembled is less than 900kg.
