ABS 800 

The compact and powerful ABS 800 unit is powered by a special hydraulic drive. A similar version of which is also used as travel motor in heavy-duty crawler cranes. The ABS 800 delivers a maximum torque of 27,800 Nm and a thrust of 130 tonnes from the moment the operating lever is actuated. This is without any gearbox or multiple drive losses. As a result, bores of up to 1,000 mm in diameter and lengths of up to 100 m (dependent upon subsoils) are possible.

From the ABS 800 upwards (Bore diameter > 500 mm), ABS Trenchless employs a hollow-stem auger system (HBS). With this system a special drill head and hollow-stem auger section can be used to form a larger bore around the pilot bore string without being connected to it. As the hollow-stem auger over-bores the pilot string, (which provides the necessary guidance to both auger and drill head) it in turn guides the steel pipe along the pre-established drill path.
