PR 734 Crawler tractor

PerformanceLiebherr has over 30 years of experience in the construction of hydrostatically driventractors. The high-performance Generation 4 crawler tractors are the perfectmachines for a wide variety of applications.High productivityNon-positive drive withhigh drawbar pullHigh dozing andripping powerOptimized blade designfor improved rolling ofthe materialBest levellingcharacteristicsA diversity of applicationsOutstandingmaneuverabilityLow machinecenter of gravityThe powerful Liebherr diesel engine in combination with theinnovative Liebherr travel drive guarantees ample power inall situations. The drive system does not require any gearshifting,which means that engine power is transferred tothe tracks without interruption – even when cornering.The hydrostatic travel drive enables the operator todefine the optimal travel speed and drawbar pull withease - preventing the tracks from slipping and ensuringthat maximum power is transmitted to the ground at alltimes.The blade contours of the PR 734 machine have beenfurther optimized. Improved rolling of the material enablesthe machine to achieve even higher productivity.The entire front-end superstructure of the machine istorsionally rigid and robust. In conjunction with thelong track frames, this ensures smooth operation ofthe blade at all times.The hydrostatic drive has a further advantage whenworking in confined spaces. All travel movements canbe performed quickly and without difficulty, includingcounter-rotation.The layout of the drive components results in an extremelylow machine center of gravity, which permitssafe operation during even the most challenging applicationson slopes and embankments.Liebherr hydrostatic drive• Automatic speed and torque adjustmentconstantly optimizes the machine’s powerflow in the event of load changes.• Even at low speeds, for example in demandingripping operations, the thermalload of the hydrostatic travel drive remainslow. The high efficiency of the driveremains almost unchanged.Optimized blade design• The blades are defined by uncompromisingpenetration characteristicsand outstanding rolling of thematerial. The sloping top cornersof the blade furthermore allowthe operator to quickly ascertainblade filling.• Robustly-built using wear-resistantmaterials, Liebherr blades excelunder even the most demandingconditions.PR 734 Litronic5
