plete provider of timber handling equipment to
the timber industry. An industrial lift arm relevant to this
sector is available for all L 514 - L 580 wheel loaders as
an alternative to the standard lift arm, with no effect on
price. Wheel loaders with special grapples and buckets
for the timber industry are being used more and more
often, in the same way as special solutions like the
LogHandler.
Material handling machines
Liebherr timber material handlers are especially
designed for log handling operations. Mainly used in saw mills, timber yards and paper mills for
perfect performance with high mobility and versatility.
The new design and it´s advance engine and drive train
technology are an integrated part of the Liebherr material handler.
Electric material handling machines
Liebherr electric material handling machines are

quick change system, the comprehensive range of working tools enables material handling machines to achieve
a high degree of flexibility and diversity. The quiet electric
drive system and the reliability of the hydraulic components reduce the machine's maintenance costs considerably. Maintenance costs are minimised and at the same
time, any downtime of the material handling machines is
reduced. The product range of electric machines from
Liebherr produces very little noise. In operation, it generates 4 to 5 dB less than a comparable machine with a
diesel engine.

handling has led to the development and implementation
of numerous application-specific options for crawler tractors. The highest level of reliability, low operating costs
and high production performance are the result and help
to increase the client's competitiveness.

handlers are ideal for demanding timber handling operations. The telescopic handlers are available in four versions with lift heights of 10 to 13 metres and lift capacities
of between 4.1 t and 5.0 t.

Performance
The Liebherr driveline allows different orientation for the
Liebherr diesel engine. In the wheel loaders L 524 - L 556
the diesel engine is rotated through 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.
Reliability
All material handlers have been subjected to intense
endurance testing and fulfill Liebherr's standard of
superior quality, even under the most extreme conditions.
Its well-developed concept and proven quality make
Liebherr wheel loaders the benchmark for reliability.
Comfort
The ultra-modern cab design with advanced ergonomics,
continuously variable Liebherr driveline for uninterrupted
tractive force, Liebherr ride control - installed as
standard on the L 550 - L 580 models, optimum weight
distribution and easy service access thanks to unique
engine installation position lead to extraordinary overall
comfort.
Economy
Compared to conventional transmission systems, the
hydrostatic driveline with Liebherr Power Efficiency
achieves a reduction in fuel consumption for wheel
loaders of up to 25%. This reduces operating costs and
environmental pollution.
