Krupp track-mounted drill and pile-driver I & II
Foundations – Track-mounted pile-drivers
The Krupp track-mounted drill and pile-driver has been especially designed and built for use on Deutsche Bahn construction sites. They can build foundations, without use of the adjacent track, using pile-driving and twist-in drilling methods. An independent traction drive enables working on the construction track without use of a work locomotive. The rams can be used flexibly due to the large load-carrying capacities with long outreach.
Functional Characteristics
- Work runs free of adjacent track and under switched off contact line
- Increased stability thanks to large self-weight and low centre of gravity
- Large diameter pipes can be driven using the existing hydraulics system (without additional unit)
- Fast conversion from pile driving to drilling equipment, compatible with the existing technology
- Piled and drilled foundations for Deutsche Bahn AG masts and signal gantries
- “In-hole” rock drilling and driving large diameter pipes with diameters up to 1,040 mm
- Foundations for temporary bridges
- Making trench or pit supports
- Loading and setting work
- Optional equipping with a diesel pile hammer – D 22 (piston weight 2.2 t) and therefore easy absorption of the heaviest pile driven material
