GRUNDODRILL – 18ACS
TRAILBLAZER
MAKES AN IMPACT IN ALL SOILS
01. Hydraulically-adjustable and vibration – dampened comfort cabin – user-friendly, clear layout, can be positioned flexibly
02. Large rod magazine – up to 225 m drill rods on board (with TD73 equipment)
03. Anchoring system for enhanced stability while drilling
04. Hydraulic loading crane for self-sufficient handling of optional stacking boxes, drilling rods and attachments
05. Bentonite collecting tray – optionally with Bentonite suction pump
06. Two stabilisers – maximum stability, variable inclination of the cradle for an ideal penetration angle
07. Broad undercarriage – with rubberised steel tracks – extremely mobile and self-supporting
08. High performance bentonite pump – for rapid reaming speed and large reaming diameters
09. Diesel engine with the highest output of its class – low fuel consumption, low noise and emission levels
10. Large GRP hood – easily accessible for service and maintenance

POWER SUPPLY ON THE ISLAND OF SYLT COMPLETELY CONVERTED TO UNDERGROUND CABLING
Thanks to trenchless technology, electrical power on the North Sea island of Sylt will soon only flow underground. Schleswig-Holstein Networks AG (SH Netz) has invested an impressive €16.5 million to optimise the power supply and to dismantle more than 7 km of 60,000 volt overhead lines.
For the new underground supply, a 15 km long, 110.000 V power line weighing around 800 t and was installed through the bottom of the North Sea and continued from there via a new high-voltage land cable to the transformer station on the island in Keitum.
The installation of the empty pipes for the connection of the sea cable in the mudflats and the power cables on the island was a case for the Nodig professionals from the contractor Paasch, who mainly applied the HDD method for this task.
