Technical description Engine Power rating according to ISO 9249, 270 kw (362 hp) at 2000 rpm Engine type Liebherr D 936 L A6 Fuel tank 700 l capacity with continuous level indicator and reserve warning Engine complies with NRMM exhaust certification EPA/CARB Tier 3 and 97/68 EC Stage III A. 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. Pumps for working tools Separate pump for kinematics Hydraulic oil tank Max. working pressure 2x 240 l/min 137 l/min 600 l 350 bar The cleaning of the hydraulic oils occurs via an electronically monitored pressure and return filter. Any clogging is shown on the monitor in the cab. The use of synthetic environmentally friendly oil is also possible. Control The control system - developed and manufactured by Liebherr - is designed to withstand extreme temperatures and the many heavyduty construction tasks for which this machine has been designed. Complete machine operating data are displayed on a high resolution monitor. A GSM modem allows for remote inquiry of machine data and error indications. 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 technology system. Error indications are automatically displayed on the 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.

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. Noise emissions correspond with 2000/14/EC directive on noise emission by equipment used outdoors. LB 24

PDE - Process data recording (Additional equipment) This module constantly calculates and stores the current working processes. Measurements Measurements are constantly calculated during the working process. No special measuring process is required. External systems can also be connected to the system. PDE - diagram Display of measurement data Measurement data relevant to the working process is displayed on the monitor in the cab. The operator can then control the process and, if necessary, correct it. Working process interruption The working process and the measurement can be interrupted at any time. The measurements are automatically continued upon resumption of work. External sensors Storage of measurement and machine data All data is stored on a memory card. This can be read via a PC. Thereby an evaluation and processing of data can also be performed at a later time. For example, for: Example of a protocol (in required language) client certifications conveying daily production data, down time, etc. Soil condition report Printing data A protocol can be printed out from the cab printer after each working process. Data transmission A GSM modem can be connected to the PDE making long distance data transmission possible. LB 24 11
