Ground Pressure Visualization

Kelly Visualization

Features:• The actual ground pressure is calculated in real time• The maximum admissible ground pressure can be

individually predefined• The utilization is continuously calculated and displayed on

the monitor in the operator’s cab• Audible and visual warnings when the predefined values

are approached

Your benefits:• Increased safety on the jobsite due to consideration of

prevailing ground conditions• Higher operator comfort thanks to clearly displayed

information and warning signals• Prevention of critical or stressful situations before

they occur• User-friendly and intuitive handling in the operator’s cab

Your benefits:• Time saving: the operator no longer needs to search for

the interlocking recesses• Higher availability: the machine needs less repair and

maintenance work• More safety: correct locking prevents damage to the

Kelly bar• Cost reduction: smooth operation results in higher

performance and less wear

LIPOS®

Using factory-mounted components, Liebherr’s positioning system LIPOS® allows for the direct integration of a Trimble or Leica machine control system into its process data recording and reporting systems. The positioning systems from Trimble or Leica for piling and drilling rigs are based on state-of-the-art Differential Global Navigation Satellite Systems (DGNSS) technology and so create the ideal conditions for a precise and efficient positioning of Liebherr machines and their wor-king tools.

LIPOS® includes a fixture for the easy and quick installation of hardware without the need to change the machine structure. DGNSS data are integrated in the process data recording system (PDE®) through a software enhancement.

The GNSS antennae are mounted on the leader with an innovative mechanical mounting system so enabling optimum signal quality and intensity. The combination of the visualized digitized drilling plans with the actual DGNSS and machine data assists the operator to exactly position and precisely execute the drilling process.

The integration of a machine control system from Trimble or Leica allows for a comprehensive and consistent recording of positioning data in PDE® as well as the visualization and analysis in the Process Data Reporting (PDR2) software. LiDAT® data transmission enables the automated transfer of recorded data via GSM and GPRS from the machine to the reporting software PDR2. Reports generated in PDR2 can be used for traceability of the application and proof of quality. The positioning system LIPOS® is seamlessly integrated into existing Liebherr digital solutions and compatible for a wide range of Liebherr deep foundation machines.
