In deep deposit exploration, all work flows must be closely coordinated, so that an optimum drilling process can be guaranteed. Terra Invader rigs made by HERRENKNECHT VERTICAL are designed in such a way that all processes can be precisely directed from the driller’s cabin, giving them a high level of working safety.

In Terra Invader rigs, the supply and removal of drill pipes and casing in the drill hole is carried out by a hydraulic arm known as the pipe handler. This reduces physically strenuous work to a minimum and increases to a maximum the level of working safety. The pipe handler’s hydraulic control system means it is very precise and, together with the hydraulic cylinder hoisting system, makes for a high tripping speed.

After the pipe handler has lifted the drill pipe or the casing from horizontal storage at the well site to the work platform, it passes them on to the elevator at the top drive, which is controlled by a hydraulic cylinder hoisting system. The hoist system has a lifting height of 22 meters and works evenly and precisely from the first millimeter. Delayed or uneven reactions are avoided and this means work in the drill hole can be very precise. In addition, the cylinder hoisting system can produce both push and pull movements, allowing the drill hole to be controlled sensitively, which in turn guarantees a particularly high level of drill hole safety.

The deep drilling rig is steered from the driller’s cabin. With a minimum of personnel, the entire pipe handling process and all other work processes, such as connecting drill pipes and casing or controlling the top drive, can be precisely directed and reliably monitored. Therefore, no personnel need to be in danger areas.
