GRUNDODRILL – 28N
TOP PERFORMER
POWER VEHICLE
SELF-SUPPORTING AND DYNAMIC
ACHIEVES PEAK VALUES IN EVERY DISCIPLINE
- The existing drive power of 224kW is 100% converted into drilling power and is absolutely unique in the power class up to 300 kN pulling force.
- The Bentonite pump supplies max. 650 l/min. for maximum productivity and fast drilling progress, even with large upsizing diameters.
- The highly efficient engine technology with emissions standard Tier V has particularly low noise and emissions and is frugal in consumption.
POWERFUL DRIVE
- Convertible for cable-guided boring for tracking in challenging terrains and great depths
- Rack and pinion drive (toothed rack)
- Stepless adjustment of torque and speed, maximum rotational power and maximum productivity at any speed
- Optimum adaptation to ground conditions and requirements
01. Anchoring system for increased stability while drilling. Integrated high-pressure cleaner – for convenient cleaning of drill rig and automatic cleaning of the drill rods during upsizing/pipe pulling
02. Automatic rod exchange, high productivity, even wear of all rods due to a precise approach of the magazine bays. The largest rod magazine 288 m on board
03. Comfortable swiveling cabin for high operator comfort and convenience, clearly arranged with flexible positioning
04. Large GFRP service hood, easily accessible for service and maintenance
05. Biggest Diesel engine of its class – 224 kW drive capacity for simultaneous operation of all main functions under full load
06. Extra-wide rubberised steel track undercarriage, extremely mobile and self-supporting
07. Two stabilisers – maximum stability, variable cradle inclinationfor an ideal penetration angle
