Water cooled, V 8 cylinder Liebherr diesel engine, model D 9408 TI E, turbocharged with intercooler, power rating according to ISO 9249 : 536 HP at 1900 rpm. The automatic limiting load control adapts perfectly the power of the main users to the present engine speed. Fuel tank: 230 gal capacity with continuous level indicator and reserve warning. Consists of single row ballbearing, fixed axial piston hydraulic motor, spring loaded and hydraulically released multi disc holding brake, planetary gearbox and pinion. Free swing with hydraulic moment control reduces wear to a minimum, because rotation moment is sustained through the hydraulic system by the diesel engine. Swing speed from 0 4.5 rpm is continuously variable. 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. Pump for working tools: 2x 79 gal/min Separate pump for kinematics: 38 gal/min Hydraulic oil tank: 218 gal Max. working pressure: 5076 PSI No auxiliary power packs are required as application specific hydraulics supply power to all components. 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. 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. 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 crane is equipped with proportional control for all movements, which can be carried out simultaneously. The Redundant control system allows restricted operation of the machine in the event of a failure on the electronic base control or its sensors. Two joysticks are required for operation. Pedal control can be changed to hand control. Options : PDE : Process data recording GSM modem Propulsion through axial piston motor, hydraulically released spring loaded multi disc brake, maintenance free crawler tracks, hydraulic chain tensioning device.

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.

A push button increases or reduces the rig radius, without modifying the adjusted inclination. The length of the unreeled rope is measured on the crowd winch and displayed in large letters on the cab screen. The vibrator control consists of stepless adjustment of the vibrator frequency, automatic clamping head system and stepless adjustment of eccentrics. An interface transmits the data of the control system, e.g. working depth to the connected PDE system. 10 LRB 155
(Additional equipment) Measurements are constantly calculated during the working process. No special measuring process is required. External systems can also be connected to the system. 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. The working process and the measurement can be interrupted at any time. The measurements are automatically continued upon resumption of work. External sensors Example of a protocol (in required language): 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: client certifications conveying daily production data, down time, etc. Soil condition report A protocol can be printed out from the cab printer after each working process. A GSM modem can be connected to the PDE making long distance data transmission possible. LRB 155 11
