Wagon-mounted pile-drivers O&K II
Foundations – Track-mounted pile-drivers
The O&K (I and II) wagon-mounted pile-drivers have been especially designed and built for use on Deutsche Bahn AG construction sites. They are suitable for making piled foundations for Deutsche Bahn AG catenary supports, in particular signal gantries as well as for making foundations for emergency bridges and trench and pit supports.
Functional Characteristics
- Work runs free of adjacent track and with switched off contact line
- Fast tooling up and tool removal on site
- High load carrying capacity
- Extraordinarily long outreach
- Flexible deployment
- Execution of work that is not possible with other track-mounted pile-drivers
- Special feature of the O&K II: Permanent integration of the work unit on an automotive bogie, additional support, can be deployed on blocked sections of tracks without a working locomotive
- Driven pile foundations for Deutsche Bahn AG catenary supports
- Foundations for signal gantries
- Foundations for emergency bridges
- Making trench or pit supports
