GRUNDODRILL – 18ACS

KING OF ROCK

TRAILBLAZER
MAKES AN IMPACT IN ALL SOILS

IDEAL POWER RATIO

Drive carriages with rack and pinion:

  • Stepless adjustment of torque and speed for maximum rotational power and maximum productivity at any speed
  • Best possible adaptation to demands and soil conditions

RODS FOR EVERY PURPOSE

  • Rods TD73 and TD82 for fluid-assisted drilling
  • Twin-tube rods Elicon 95 for rock drilling
  • Quick conversion from fluid-assisted to rock drilling

LIGHTNING-FAST ROD EXCHANGE

  • Fully automatic operation ensures minimal downtime, maximum productivity and relief for the machine operator
  • The on-board crane facilitates easy handling of the rods, stacking boxes and additional components
  • Rotation of drill rods within rod box possible during normal operation, which results in consistent use and consistent wear of the rods

CABLE-GUIDED DRILLING

  • The GRUNDODRILL 18ACS and the GRUNDODRILL 18N can optionally be converted for cable-guided bores when drilling in challenging terrain and at great depths
  • Cable-guided drilling is also possible in connection with EL95 twin-tube rod system

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.
