Technical description Engine Power rating according to ISO 9249, 32 kw (429 hp) at 17 rpm Liebherr D 936 A7-4 Fuel tank 7 l capacity with continuous level indicator and reserve warning Hydraulic system The main pumps are operated by a distributor gearbox. Axial piston displacement pumps work in open circuits supplying oil only when needed (flow control on demand). The hydraulic pressure peaks are absorbed by the integrated automatic pressure compensation, which relieves the pump and saves fuel. Control The control system developed and manufactured by Liebherr is designed to withstand extreme temperatures and the many heavy duty construction tasks for which this machine has been designed. Complete machine operating data are displayed on a high resolution monitor screen. A GSM/GPRS telematics module allows for remote inquiry of machine data and operational conditions. To ensure clarity of the information on display, different levels of data are shown in enlarged lettering and symbols. Control and monitoring of the sensors are also handled by this high monitor in clear text. The machine is equipped with proportional control for all movements, which can be carried out simultaneously. Two joysticks are required for operation. Pedal control can be changed to hand control. Option: : Process data recording Pumps for working tools Separate pump for kinematics Max. working pressure 2x 27 l/min 13 l/min 6 l 35 The cleaning of the hydraulic oils occurs via an electronically monitored pressure and return filter. Any clogging is shown on the display in the cab. The use of synthetic environmentally friendly oil is also possible.

Propulsion is via a maintenance-free planetary gearbox in oil bath. Load support by the hydraulic system; additional safety factor by a spring loaded, multi disc holding brake. All line pull values are effective values. The efficiency factor of approx. 25% has already been deducted. Swing Consists of triple-row roller bearing with external teeth and two swing drives, fixed axial piston hydraulic motor, spring loaded and hydraulically released multi disc holding brake, planetary gearbox and pinion. Selector for 3 speed ranges to increase swing precision.

The operator can enter various details (e.g. jobsite name, pile number, etc.) and start is established on a CompactFlash memory card. can be configured in a number of ways, e.g. for the connection of external sensors, for the generation of a simple protocol as graphic file and/or for a printout directly in the operator s cab. Process data reporting - PDR (additional equipment) Comprehensive data evaluation and generation of reports on a PC is possible using the software PDR. Recordings management - system can be imported and managed in PDR. The data can be imported directly from the CompactFlash card or via the Liebherr telematics system LiDAT. Certain recordings, e.g. for a particular day or jobsite, can be found using filter functions. Viewing data - The data in each record is displayed tabularly. Combining several recordings provides results, for example, regarding the total concrete consumption or the average depth. Furthermore, a diagram editor is available for quick analysis. Generating reports - A vital element of PDR is the report generator, which allows for the generation of thickness or even the desired logo can be configured.
