Low operating costs
Minimum costs, |
Liebherr wheel loaders are unbeatable for economy |
|
High handling capacity |
compared to conventionally driven wheel loaders. |
|
|
This is due to the following factors: |
|
|
− |
Low fuel consumption thanks to higher efficiency |
|
|
and low operating weight. Thanks to the newly de- |
|
|
veloped Liebherr Power Efficiency system the large |
|
|
wheel loaders use the same amount of fuel com- |
|
|
pared to their predecessors in the Tier 3 generation. |
|
− |
Practically no brake wear thanks to the hydraulic |
|
|
braking action of the driveline; this ultimately reduc- |
|
|
es repair costs. |
|
− |
Reduced tire wear due to continuous traction con- |

|
trol. Depending on the working conditions, there is |
|
|
up to 25 % less wear. |
Active environmental protection
Economical use |
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 33,070 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 |

Liebherr driveline L 550 – L 556
•Optimum weight distribution thanks to transverse installation of the diesel engine.
•The diesel engine as well as the variable displacement pumps mounted on the engine act as counterweight, therefore allowing higher tipping loads at low operating weight.
•Compact design improves visibility in all directions.

Performance
The Liebherr driveline allows for optimal positioning of the Liebherr diesel engine. In the wheel loaders L 550 – L 556 the diesel engine is rotated 90° and mounted transverse to the direction of travel. In the L 566 – L 580 it is 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 |
|
for higher tipping loads at low operating weight. This |
|
leads to significantly higher productivity since there is |
|
no need for unnecessary counterweight. |
Ultra modern Liebherr driveline
Innovative technology Tractive force and speed are automatically adjusted to the requirements of the operator 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 industrial lift arm is available as an alternative to the standard Z-bar linkage, at no additional cost. The industrial lift arm features a parallel guide arrangement and high torque in the upper lifting range - ideal properties for larger and heavier attachments as well as transporting heavy loads. With its industrial lift arm Liebherr can now offer a continuous and uniform solution for industrial operations over the entire range of large machines. With their compact design, Liebherr wheel loaders can maneuver quickly and efficiently - the best choice for high handling capacities.
Liebherr driveline L 566 – L 580
•Optimum weight distribution due to the Liebherr diesel engine installed lengthways and the output shaft facing the rear of the machine.
•The diesel engine as well as the variable displacement pumps mounted on the engine act as counterweight, therefore allowing higher tipping loads at low operating weight.
•Compact design improves visibility in all directions.
Conventional travel gear
•Longitudinally mounted diesel engine moves the center of gravity further forward.
•Additional counterweight is needed to maintain stability and to increase the tipping load.
•This results in high operating weight and poor visibility.
L 550 - L 580 7
Cooling system
•The cooling system is mounted between the diesel engine and the cab on the rear chassis, where it can draw in clean air.
The speed of the fan is dependent on the cooling capacity, with thermosensors ensuring optimum fan speed.
•To improve visibility, the cooling system has been mounted lengthways and the unit has been redesigned to make cleaning and maintenance even easier.
•The cooling system has been adjusted to meet the demands of the new engine technology.
•The reversible fan drive is a standard feature, a particle protection for the radiator and a large-mesh radiator are also available as options to prevent contamination in especially dusty atmospheres and to make cleaning easier. Minimum cleaning effort translates into more efficient work.

Reliability
All the materials used in the Liebherr wheel loaders have passed extensive tests to ensure that they meet Liebherr’s exacting standards even in the toughest conditions. The advanced concept and proven quality make Liebherr wheel loaders the benchmark of reliability.
Reliable Liebherr driveline
Fewer components The Liebherr driveline includes a self-locking hydraulic brake, which means the additional wet brake discs are wear-free since there is no need for a reversing gear unit. There are fewer components needed, which minimizes the number of parts susceptible to wear.
Controlled cooling
The intelligent answer The cooling fan is driven independently 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 output, thus preventing the engine from overheating.
