EconomyThe Liebherr driveline with Liebherr Power Efficiency (LPE) reduces wheel loader fuelconsumption by 25% or more when compared to conventional travel gears!Low Operating CostsMinimum Costs,High Handling CapacityWhen it comes to economy, conventional wheel loadersare no match for Liebherr machines, mainly due to thefollowing factors: Low fuel consumption thanks to higher efficiency andlow operating weight. Thanks to the newly developedLiebherr Power Efficiency system the generationTier 4i wheel loaders L 524 – L 542 use up to 8% lessfuel compared to their predecessors. Practically no brake wear thanks to the hydraulic brakingaction of the driveline; this ultimately reduces repaircosts. Reduced tire wear due to continuous traction control.Depending on the working conditions, there is up to 25%less wear.Active Environmental ProtectionEconomical Useof ResourcesThe reduction in fuel lowers emissions, thus activelyprotecting resources:0.3 gal of fuel produces up to 7 lb of carbon dioxide (CO2).By saving up to 1.3 gal per operating hour, up to 33,070 lbless CO2 is produced in 1,000 operating hours. Not onlyare operating costs reduced but the environment alsobenefits from the drastically reduced emissions.Low Noise EmissionThe innovative driveline concept means much lower noiseemission – Liebherr wheel loaders are significantly quieterin operation.Liebherr Power Efficiency (LPE)Reduced Tire Wear The newly developed system knownas Liebherr Power Efficiency (LPE)optimizes the interaction betweenthe drive components. It optimizesthe position of the working point inthe characteristic map with regardto the degree of efficiency. The tractive force is controlledcontinuously. This stops wheel spinsand reduces tire wear by up to 25%. LPE saves up to an additional 8%in fuel compared to wheel loaderswhere the system is not used.Reduced Brake Wear Even under the toughest workingconditions, the Liebherr travel drivealways brakes hydraulically. Themechanical service brake only actsas a support and is therefore subjectto hardly any wear.L 524 – L 5425

PerformanceThe Liebherr driveline allows for optimal positioning of the diesel engine. In this wheelloader class the diesel engine is rotated 90 and mounted transverse to the direction oftravel. Compared to conventionally driven wheel loaders, the operating weight is muchlower, the tipping load is higher, and more material can be moved each operating hour.Higher Performance, Lower WeightHigher ProductivityThe combination of the Liebherr driveline and the uniqueposition of the diesel engine allows for higher tipping loads at lowoperating weight. This leads to significantly higher productivitysince there is no need for unnecessary counterweight.Ultra Modern Liebherr DrivelineInnovative Technology Tractive force and speed are automatically adjusted to therequirements of the operator without shifting. There is no needfor a mechanical reverse gear because the travel direction ischanged hydraulically.Flexibility Puts Them AheadAn All-Purpose Loader The parallel linkage is available as an alternative to the standardZ-bar linkage, at no additional cost. The parallel linkage featuresa parallel guide arrangement and high torque in the upper liftingrange – ideal properties for larger and heavier attachmentsas well as transporting heavy loads. With its parallel linkageLiebherr offers a continuous and uniform solution for industrialoperations over the entire range of all-round loaders. With theircompact design, Liebherr wheel loaders can maneuver quicklyand efficiently – the best choice for high handling capacities.Power All-Roundersfor IndustryThe new generation Tier 4i all-round wheel loader models havebeen specifically developed for industrial use in terms of theirperformance and stability and ensure even higher productivityand efficiency. In addition to increasing the engine performance,the tipping loads of the whole range have been increased.Furthermore the steel structure has been reinforced and thehydraulic system‘s performance enhanced. That, together withthe wide range of equipment available makes these all-roundloaders the perfect solution for all industrial uses.Conventional Travel GearAn All-Purpose Loader Longitudinally mounted dieselengine moves the center of gravityfurther forward. The choice between parallel (P) andZ-bar linkage means that the loadercan always be configured to suitthe customer’s specific tasks: P forindustrial use, Z for conventionalmaterial handling. Much more additionalcounterweight is needed to maintainstability and to increase the tippingload. This leads to high operating weightand poor visibility.L 524 – L 5427
Liebherr Driveline The Liebherr driveline consistsof two hydraulic motors, whichaccelerate the loader continuouslyfrom a standstill to maximumspeed, either forwards or inreverse – without a manual gearshift and a reversing gear unit.8L 524 – L 542
ReliabilityAll the materials used in the Liebherr wheel loaders have passed extensive tests to ensurethat they meet Liebherr’s exacting standards even in the toughest conditions. The advancedconcept and proven quality make Liebherr wheel loaders the benchmark of reliability.Reliable Liebherr DrivelineFewer ComponentsThe Liebherr driveline includes a self-locking hydraulicbrake, which means the additional wet brake discs arewear-free since there is no need for a reversing gear unit.There are fewer components needed, which minimizes thenumber of parts susceptible to wear.Controlled CoolingThe IntelligentAnswerThe cooling fan is driven independently from the dieselengine and produces only the cooling air output which isactually required. Heat sensors ensure reliable control. Ifoverheating should occur, the wheel loader automaticallyshifts down to first travel speed range. The reduced powerconsumption protects the engine from overheating. At thesame time, the fan speed is increased to maximum output,thus preventing the engine from overheating.Components Meet Manufacturer’s QualityStandardsEverything froma Single SourceMain components such as hydraulic cylinders andelectronics are developed and manufactured by Liebherrto ensure the highest quality standards. Liebherr WheelLoaders are carefully designed down to the smallest detailto provide customers with the perfect machine solution tomatch the application-specific demands while achievingmaximum productivity and longevity.Optimized EngineTechnologyAs well as further developments towards greaterenvironmental compatibility, the new generation of dieselengines have been optimized in a number of other respects.In addition to Common Rail technology a diesel particlefilter significantly reduces exhaust emissions. With activeregeneration, in most operational circumstances thisfiltration process ensures efficient, uninterrupted work.Cooling SystemDiesel Engine The radiator is installed on the rearsection of the vehicle, between thediesel engine and the cabin. Coolingair is drawn in directly behind thecabin and blown out upwards atthe rear. The fan speed is variedautomatically by heat sensors thatdetermine the amount of coolingneeded. Common Rail technology optimizes thecombustion process and reduces emissions. The reversible fan drive isa standard feature. Further reduction of particle emissions due tothe diesel particle filter with oxidation catalyticconverter. Active regeneration ensures efficient,uninterrupted work. Proactive intervention of Liebherr PowerEfficiency (LPE) in the engine managementsystem increases efficiency.L 524 – L 5429
Liebherr Control Lever The Liebherr control lever is used to manageall travel and working movements of the wheelloader. This ensures the operator’s left handalways remains on the steering wheel andtherefore increases safety. The operator controlsthe following functions with his right hand:– Raise and lower attachment– Tilt and crowd– Automatic bucket return to dig– Change of travel direction withsimultaneous travel start– Auxiliary control buttons for additional hydraulic functions10L 524 – L 542
