A characteristic feature of deep foundation is that many of its products are not visible from the surface at the time

of their construction. At the same time, however, these products are of fundamental importance for the buildings

to be erected on them. Therefore quality assurance is a vital factor for the successful cooperation of all parties

involved in the construction project. With its PDE® process data recording system and its PDR process data

reporting software Liebherr offers two important elements for modern deep foundation applications. Combining

the systems shown below improves the documentation of the working processes, facilitates supporting docu-

mentation and settlements, shortens reaction time to changing soil conditions and indicates potential for opti-

mizing future jobsite planning.

The PDE

process data recording system is available for Liebherr machines of the LB, LRB, LRH and HS series

and serves to electronically record and visualize the process data. Operation and display is carried out via the

PDE

colour touchscreen in the operator’s cab. The PDE records process data from the Litronic control system

(e.g. pressure or rope length measurement) as well as data from external sensors (e.g. frequency transmitter

or concrete pressure transmitter). Depending on the working process the data are interlinked and stored on

a CompactFlash (CF) memory card together with individually conﬁgurable details (such as jobsite name, pile

number, date, time etc.). Using the optional printer protocols can be printed in the operator’s cab directly after

completion of the working process.
