L 550 - L 586 Wheel Loaders
Wheel Loaders L 550 - L 586 2plus2 2plus2 Tipping load, articulated: 25,700 lb – 45,050 lb L 550 2plus2 L 566 2plus2 L 580 2plus2 Tipping load, articulated: 25,700 lb Bucket capacity: 4.2 yd³ 36,450 lb Operating weight: Engine output: 177 HP/130 kW Tipping load, articulated: 34,300 lb Bucket capacity: 5.2 yd³ 49,625 lb Operating weight: Engine output: 259 HP/190 kW Tipping load, articulated: 39,700 lb Bucket capacity: 6.5 yd³ 54,200 lb Operating weight: Engine output: 272 HP/200 kW L 586 2plus2 Tipping load, articulated: 45,050 lb Bucket capacity: 7.2 yd³ 69,200 lb Operating weight: Engine output: 340 HP/250 kW 2 L 550 2plus2 – L 586 2plus2 Economy Reliability The Liebherr driveline reduces wheel loader fuel consumption by 25 % or more when compared to conventional travel gears! Liebherr wheel loaders save up to 1.3 gallons of fuel per operating hour, significantly reducing operating costs and environmental pollution. All the materials used in Liebherr wheel loaders have passed long-term tests to ensure that they meet Liebherr’s exacting standards even in the toughest conditions. The mature concept and proven quality make Liebherr wheel loaders the benchmark for reliability. Performance Comfort The Liebherr driveline allows the Liebherr diesel engine to be mounted lengthways in the rear, with the output shaft facing backwards. Compared to conventionally driven wheel loaders, the operating weight is much lower, the tipping load is higher, and more material can be moved each operating hour. The ultra-modern cab design with advanced ergonomics, continuously variable Liebherr driveline with 2plus2 gearbox for uninterrupted tractive force, standard Liebherr ride control, optimum weight distribution and easy service access due to unique engine installation position lead to extraordinary overall comfort.

Economy The Liebherr driveline reduces wheel loader fuel consumption by 25 % or more when compared to conventional travel gears. Liebherr wheel loaders save up to 1.3 gallons of fuel per operating hour, significantly reducing operating costs and environmental pollution. Low operating costs Minimum costs, High handling capacity Liebherr wheel loaders are unbeatable for economy compared to conventionally driven wheel loaders. This is due to the following factors: − Low fuel consumption thanks to higher efficiency and low operating weight. Liebherr wheel loaders consume up to 1.3 gallons fuel per operating hour less than conventionally driven wheel loaders in the same working conditions. − Practically no brake wear thanks to the hydraulic braking action of the driveline; this ultimately eliminates consequent repair costs. − Reduced tire wear due to continuous traction control. Depending on the working conditions, there is up to 25 % less wear. Active environmental protection Economical use of resources The reduction in fuel lowers emissions, thus actively protecting 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 33,069 lb less CO2 is produced in 1,000 operating hours. Not only are operating costs reduced but the environment also benefits from the drastically reduced emissions. Low noise emission The innovative driveline concept means much lower noise emission – Liebherr wheel loaders are significantly quieter in operation. Reduced brake wear Reduced tire wear • Even under the toughest working conditions, the Liebherr travel drive always brakes hydraulically. The mechanical service brake only acts as a support and is therefore subject to hardly any wear. • The tractive force can be adjusted continuously. This stops wheel spins and reduces tire wear by up to 25 %. L 550 2plus2 – L 586 2plus2 5 Liebherr driveline • Optimum weight distribution thanks to lengthways-installed Liebherr diesel engine, output shaft is facing the rear. • The variable displacement pumps on the engine act as counterweight, thus allowing higher tipping loads at low operating weight. • Compact design improves visibility in all directions 6 L 550 2plus2 – L 586 2plus2 Performance The Liebherr driveline allows the Liebherr diesel engine to be mounted lengthways in the rear, with the output shaft facing backwards. Compared to conventionally driven wheel loaders, the operating weight is much lower, the tipping load is higher, and more material can be moved each operating hour. Higher performance, lower weight Higher productivity The combination of the Liebherr driveline and the unique position of the Liebherr diesel engine allows higher tipping loads at low operating weight. This leads to significantly higher productivity because there is no need for unnecessary counterweight. Ultra modern Liebherr driveline Innovative technology The large Liebherr wheel loaders are equipped with the 2plus2 gearbox. Tractive force and speed are automatically adjusted to the requirements of the driver without shifting. There is no need for a mechanical reverse gear because the travel direction is changed hydraulically. Flexibility puts them ahead An all-purpose loader The Lumberjack is the ideal tool to complement the available equipment for the large Liebherr wheel loaders. This „torque increase“ is the perfect additional system for your requirements, especially when operating with heavy equipment and loads. Their compact design allows these wheel loaders to maneuver quickly and efficiently – an ideal basis for high handling capacity. Conventional travel gear An all-purpose loader • Longitudinally mounted diesel engine moves the center of gravity further forward • The choice between Lumberjack or Z pattern linkage means that the loader can always be configured for every job application – Lumberjack for industrial use; Z for conventional material handling. • Additional counterweight is needed to maintain stability and to increase the tipping load. • This results in high operating weight and bad visibility L 550 2plus2 – L 586 2plus2 7 Liebherr driveline • The Liebherr driveline consists of two hydraulic motors which accelerate the loader continuously from a standstill to maximum speed, either forwards or in reverse – with a 2plus2 gearbox – but without a reversing gear unit. 8 L 550 2plus2 – L 586 2plus2 Reliability All the materials used in Liebherr wheel loaders have passed long term tests to ensure that they meet Liebherr’s exacting standards even in the toughest conditions. The mature concept and proven quality make Liebherr wheel loaders the benchmark for reliability. Reliable Liebherr driveline Fewer components The Liebherr driveline includes a self-locking hydraulic brake, which means the additional wet brake discs are effectively wear-free. There is no need for a reversing gear unit – thus minimizing the number of parts susceptible to wear. Controlled cooling The intelligent answer The cooling fan is not driven directly from the Liebherr diesel engine and produces only the cooling air output which is actually required. Heat sensors ensure reliable control. If overheating should occur, the wheel loader automatically shifts down to first travel speed range. The reduced power consumption protects the engine from overheating. At the same time, the fan speed is increased to maximum value, thus preventing the engine from overheating. Components meet manufacturer’s quality standards Everything from a single source Important components such as the engine, hydraulic rams and electronics are developed and manufactured by Liebherr itself. This ensures co-ordinated quality from the manufacturer down to the smallest detail. Liebherr components guarantee maximum performance and reliability. Cooling system Liebherr’s own components • The cooling system is fitted on the rear section between the diesel engine and the operator’s cab. The cooling air is drawn in directly behind the cab and blown out upwards at the rear. The fan speed is varied automatically by heat sensors that determine the amount of cooling needed. • Liebherr has many years of experience in design, development and construction of diesel engines, hydraulic rams and electronic components. They are matched together down to the smallest detail to guarantee optimum interaction and performance. • A reversible fan drive to expel dust from the radiator can be specified as an optional extra. L 550 2plus2 – L 586 2plus2 9 Liebherr control lever • The Liebherr control lever is used to manage all travel and working movements of the wheel loader, so that the operator’s left hand can always remain on the steering wheel. There is no need to let go of the steering wheel increasing overall safety. The operator controls the following functions with his right hand: – Raise and lower attachment – Fill and dump the bucket – Automatic bucket return to dig – Kick down and Gear Hold function – Auxiliary control buttons for additional hydraulic functions – Change of travel direction with simultaneous travel start 10 L 550 2plus2 – L 586 2plus2 Comfort The ultra modern cab design with advanced ergonomics, continuously variable Liebherr driveline with 2plus2 gearbox for uninterrupted tractive force, standard Liebherr ride control, optimum weight distribution and easy service access due to unique engine installation position lead to extraordinary overall comfort. Top-class cabin design Comfort cab The ultra-modern, ergonomically planned cabin design allows the operator to achieve better performance and productivity in the greatest possible comfort. The displays, controls and operator’s seat are carefully coordinated to form a perfect ergonomic unit. Liebherr control lever All the working and travel functions are operated precisely and sensitively from a single control lever. This means accurate and safe handling, and the left hand always remains on the steering wheel. This increases the safety at the job site. Liebherr driveline Continuously variable transmission The Liebherr driveline with its 2plus2 gearbox allows continuous regulation of acceleration in all speed ranges, without noticeable gear shifting or interruption in tractive force. Service access Easy maintenance Because the Liebherr diesel engine is rotated by 180°, the hydraulic pumps, hydraulic tank, hydraulic tank cut-off valve, air filter and battery main switch can be reached easily and safely from ground level by opening a single engine compartment hood. The engine, pump distributor gear and cooling system are easily accessible by opening the engine cover. Hydrostatic fan drive The cooling system is positioned directly behind the cab, which means there is less dirt and therefore less maintenance and cleaning resulting in time and cost savings! Service access Powerful air-conditioning system • The unique position of the Liebherr diesel engine provides perfect accessibility for maintenance. The hydraulic pumps, hydraulic tank, hydraulic tank cut-off valve and battery main switch can be easily and safely accessed from ground level by opening a single engine compartment hood. • The standard equipped air-conditioning system of the large wheel loaders provides the greatest operator comfort for high productivity. • The air flow is controlled at 4 different levels – an automatic air-conditioning system is available as an option. – Air flow in the feet area – Defroster – Air flow in the head area – Air flow in the body area L 550 2plus2 – L 586 2plus2 11 L 550 – L 580 Technical Data Engine L 550 L 566 L 580 2plus2 2plus2 2plus2 Liebherr diesel engine ____________ D934S A6 Design ________________________ Liebherr diesel D936L A6 D936L A6 engine, water-cooled, exhaust turbo charged with intercooler Cylinder inline ________________ 4 6 6 Combustion process ________ PLD Rated output according to ISO 9249 __________ hp/kW 177/130 259/190 272/200 at RPM 2000 2000 2000 907 975 Max. torque ______________ lb ft 611 at RPM 1500 1300 1300 Displacement ____________ gal 1.7 2.8 2.8 Bore/Stroke ________________ in 4.8”/5.35” 4.8”/5.91” 4.8”/5.91” Air cleaner __________________________ Dry type with main and safety element, pre-cleaner, service indicator on LCD display Electrical system Operating voltage __________V 24 24 24 Capacity __________________ Ah 143 170 170 Alternator ________________V/A 28/80 28/80 28/80 ____________ Starter motor V/hp 24/9 24/9 24/9 Attachment Hydraulics Design ______________________________ “Load-sensing” swash plate type variable flow pump with output and flow control, and pressure cut-off in the control block Cooling ______________________________ Hydraulic oil cooling using thermostatically controlled fan and oil cooler Filtering ____________________________ Return line filter in the hydraulic reservoir Control ______________________________ “Liebherr-Joystick” with hydraulic servo control Lift circuit __________________________ Lifting, neutral, lowering and float positions controlled by Liebherr joystick with detent Tilt circuit __________________________ Tilt back, neutral, dump automatic bucket positioning L 550 L 566 L 580 2plus2 2plus2 2plus2 ____________________ Max. flow gpm 62 77 77 Max. pressure ________________ PSI 4,786 5,076 5,076 Attachment The exhaust emissions are below the limits in stage IIIA / Tier 3. __________________________ Powerful Travel Drive Stepless hydrostatic travel drive Design “2plus2” ______________ Swash plate type variable flow pump and two variable axial piston motors in closed loop circuit with one axle transfer case.

Every Liebherr dealer will provide you with this measuring tank kit free of charge or, on request, will carry out the standard fuel consumption test on your premises. It’s so easy: you simply determine the number of loading cycles that can be carried out with 1.3 gal/5 liters of diesel. The material is taken from pile A and carried over a distance of 22 yd/ 20 m to point B. The time needed for each working cycle should be 35 seconds. Discharge at point B should take place from a height of 8 ft/2.5 m. The working cycles continue until the 1.3 gal/5 liters of diesel in the external measuring tank have been used up. The loader’s fuel consumption per operating hour is calculated as follows: 3 2 1051) Number of loading cycles 1) 105 = 2) A 1 = consumption per hour in gal 1.3 gal x 3600 sec. x 0.782) 35 sec.
