Liebherr material-handling equipment – built for maximum productivity.
Robust designs using well thought-out technology mean continuously high material-handling performance com­bined with high load capacities. This is why Liebherr develop, test, and produce key components themselves, such as the diesel engine, hydraulic pumps, motors, and cylinders. This universal model range has the right mate­rial-handling equipment for every application.
A large number of the most widely differing fi tting variants and the quick-change systems from Liebherr mean effi cient material-handling performance, time savings and continu­ously high machine workloads.

Maintenance.
Service-oriented, carefully thought-out equipment designs mean short maintenance times; all maintenance points are arranged on the easily accessible service side of the engine. The semi-automatic central lubricating system provided as standard also makes time-consuming greasing and lubri­cating a thing of the past, and ensures high availability for the equipment.

The crawler material-handling equipment.
For the greatest possible material-handling effi ciency, Liebherr crawler material-handling equipment is the ideal solution, combining excellent stability with excellent range. Liebherr crawler excavators are ideal for operations in which the machine is predominantly stationary and/or where soil bearing capacity is limited.
They are stable material handlers which are designed for
high productity and fast working cycles.
Due tu the higher performance rentability will be
increased by the saved time.

Wide variety of equipment.
The equipment elements fi tted to the crawler material-han­dlers have been designed especially with material-handling operations in mind. The balanced industrial kinematic con­cepts ensure maximum working radii at high load capaci-
ties. A wide range of different industrial gooseneck booms
and industrial sticks provide the best possible equip-
ment variant for every task. Liebherr crawler excavators
are designed to shift a lot in a short time, and with-
out having to move the machine. This time saving
directly benefi ts handling capacity and achieves a
clear boost in profi tability.
Even greater adaptation to the particular task
can be provided with the new Vario Lift Plus
system, which Liebherr offers on all material-
handling excavators – the only manufacturer
to do so. With the help of holes provided on
the boom and slewing platform, the lifting
rams and the boom itself can be inserted
in a variable arrangement, which means
that a whole range of entirely different
tasks can be carried out by one mate-
rial-handling machine, selecting the
best kinematic variant in each partic-
ular case and the best possible load
capacities brought into action in
each case. Just one example is the
special plug-in variant intended for
loading and unloading ships.

Hydraulic and rigid cab elevation.
For an optimum view in the most widely differing opera­tional situations, Liebherr provide hydraulically adjust­able and rigid cab-elevation systems. Hydraulic cab elevation means that the operator can adjust his range of vision steplessly allowing the best possible range of vision for his work. The result is optimum load perform­ance and maximum productivity. To protect the driver, Liebherr also offers a wide range of different protection elements for the cab.
8
Driver’s cab.
The generous dimensions of the cab, with its wide range of storage options, provide the best possible fi elds of vision thanks to the large-area windows and the inclined super­structure edges. The air-conditioning system, the ergo­nomically designed driver’s seat, which can be adjusted in a multitude of ways, and the low noise emissions all ensure that the driver remains on top form all day long.

Multi-tine grapples.
The tried-and-trusted multi-tine grapples are essential tools for every Liebherr hydraulic excavator. Thanks to their carefully designed geometry, Liebherr multi-tine grapples are ideally matched to Liebherr machines – resulting in ex­cellent loading behaviour and high productivity.

Tool-Control and Likufix.
What is Tool Control?
Tool Control is an additional electro-hydraulic function which makes working with hydraulic add­on parts very convenient. Up to ten combinations of oil fl ows and pressures can be programmed with the name of the tool and selected directly from the display. With the help of Tool Control, the operator can select the parameters for the hydraulic tool he wishes to use with a simple press of a button – no elaborate readjustment needed when it comes to a tool change.
What is LIKUFIX?
Likufi x is a hydraulic quick-change system combined with an automatic hydraulic coupling device designed for quick, reliable changing of mechanical and hydraulic add-on tools, directly from the cab. Likufi x is the ideal supplement to Tool Control. The combination of Likufi x and Tool Control makes it possible to change hydraulic add­on tools easily – without even leaving the cab.
The technical advantages:
• Fully automatic play compensation
• Tight connection between the hydraulic circuits thanks to the hydro-mechanical compensation system
• More than 25 years experience in fully-automatic
coupling systems
• Reliable system with long service life
The convenience advantage:
• Reliable hydraulic connection free of oil leaks
• Low operating and maintenance costs
• Add-on parts can be changed from the cab
The economic advantage:
• Easy equipping of existing hydraulic excavators
• Hydraulic add-on parts changed in a matter of seconds – meaning better machine utilisation with different applications on the same unit
• Major time savings in comparison with hydraulic-hose changes
• Low operating and maintenance costs with maximum productivity
• Carefully selected use of the add-on parts for long tool service life
