Process data recording system - PDE (additional equipment)The Liebherr process data recording system PDE constantly records the relevant process data during the working process.

Process data reporting - PDR (additional equipment)Comprehensive data evaluation and generation of reports on a PC is possible using the software SCULI PDR.
