Performance
Liebherr material handling equipment is developed for the
highest productivity. A high lifting capacity and rapid work
cycles form the prerequisites of a powerful industrial material handling operation. Numerous attachment options optimise machine performance.
Reliability
Liebherr hydraulic excavators are designed and built to
operate in the harshest material handling environments.
Their rugged design, high-tensile materials and individual
components ensure maximum availability and long life
expectancy.
Comfort
Largely dimensioned and ergonomically designed, the
Liebherr excavator cab features an operator’s seat which
can be individually adjusted, as well as clearly arranged
control instruments and ideal all round view. Automatic air
conditioning guarantees an optimum temperature in the
Liebherr Feel-Good cab at all times.
Economy
The Liebherr-Litronic-System increases machine performance, reduces fuel consumption and minimises service
and maintenance costs. Due to Liebherr’s well-balanced
range, the ideal machine can always be selected to suit
every application.

Liebherr diesel engine
• Long life expectancy,
expansive cylinder capacity
and increased weight
• According to level IIIA / Tier 3
• Specially developed for
construction and industrial
machinery operation
• Oil supply even with
100 % tilt angle
• Excellent torque
Performance
The A 954 C HD Litronic has been designed for maximum production. Perfectly
harmonized, the Liebherr-developed and Liebherr-manufactured components including diesel engine, hydraulic pump and motor, as well as swing gear and cylinders, guarantee maximum performance. This results in a high lifting capacity with
rapid work and travel movements.

ReGenerationPlus
VarioLiftPlus
Liebherr provide an individual, application-related
range of diverse attachments. A straight or angled
industrial mono boom can be combined with various industrial sticks to suit any application.
The effi cient handling of materials of differing consistencies, e.g. scrap metal, wood or bulk solids,
is everyday demands on material handler equipment. This is ensured by the most effi cient use of
kinematics.
A separate hydraulic circuit with a maximum hydraulic pressure of 380 bar makes a high swing
torque possible. Rapid work cycles are achieved
through an independent control system.
Maximum performance and maximum forces are
available to the operator at all times.
The new ReGenerationPlus system on the hoist
and stick cylinders saves energy and quickly lowers the attachment.
Variable boom mounting positions for optimized lift
capacities.
Robust undercarriage
• The box-type construction of the undercarriage with securely-welded supports
provides a solid base, the greatest stability
and a long service life in every application
Litronic-System
• Increases productivity
of the excavator
• Reduces fuel consumption
• Reduces service costs
and eases operation
• Allows maximum sensitivity and
as many overlapping movements
as are required

Reliability
Liebherr material handlers prove themselves day in, day out in the most varied industrial applications all over the world. Many years of experience as the
world’s largest manufacturer of wheeled excavators, continuous development
and the introduction of the latest technology are evident in every machine,
guaranteeing absolute safety during applications. With its rugged design, and
featuring Liebherr components, the A 954 C HD Litronic has been designed for
extremely long life expectancy.
Quality in detail
Liebherr components
Liebherr develops, tests and manufactures components such as diesel engines, slewing gear, hydraulic cylinders and electronics specifi cally for
industrial machinery. Parts including engines and
pumps for example, are already being synchronized with each other as early as the construction
phase, yielding a constant standard of quality.
Functional safety
Safety-orientated components, fi tted as standard, allow high availability. The operator can thus
concentrate fully on the task at hand, due to the
integrated on-board electronics performing a constant balancing of pre-defi ned set data.
The magnet bar, fi tted as standard in the hydraulic
system, increases the operating life of the hydraulic components and serves as a service indicator.
Rugged attachments
Working attachment
The stable attachments are designed for the
harshest applications and have a long service life.
All components have been optimised using the FE
method. Stress-reducing two-sided cylinder bearings on mono and stick connections. Integrated
large diameter torsion tube for the best possible
force absorption by the attachment components.
Liebherr hydraulic cylinders
• Specifi c size for each machine
• High-grade surface coating
of the piston rods
• All Liebherr cylinders feature
special long-life sealing systems
• Shock absorption in
the working cylinders
Piping
Routing the hydraulic lines in the arm offers the
best protection against damage. The electric
cabling is made with high-grade materials, thus
guaranteeing a reliable supply to the consumer.
Functional safety
• Essential operating data is stored
and can be recalled at any time
• Control and monitoring functions increase
functional safety of the machine
• Four fi xed working modes for output discharge
facilitate an effective and effi cient operation:
– ECO-Mode: High handling and loading performance
coupled with low fuel consumption
– POWER-Mode: For maximum handling and loading
performance under severe conditions
– LIFT-Mode: For precise handling of heavy loads
– FINE-Mode: For fi ne control at precision work

Large-sized cab
• Adjustable steering column
• Operator’s seat, adjustable in height
and can also be adapted to the individual weight of the operator
• Consoles with or without possibility
of horizontal adjustment
• Large roof window
• Sun blinds
Comfort
The excavator operator is provided with an ergonomically-arranged working
area within Liebherr hydraulic excavator cabs. All switches and functions are
logically laid out, and operator’s seat, steering column and consoles can be
adjusted individually. Conditioning and concentration can thus be maintained
throughout the entire working day, guaranteeing constant, maximum productivity of the operator.
Mobile comfort
Easy access
Wide steps, ergonomically-positioned handles and
adjustable steering column allow an easy access
into the Liebherr operator’s cab.
Optimum visibility
A well-thought-out design of the uppercarriage,
featuring large glass panels and rounded edges, increase overall visibility and guarantees a safe overview of the entire working area. The best fi eld of
vision in all directions and from any cab position.
Pleasant surroundings
Reduced engine speed together with elaborate
sound insulation, as well as optimised hydraulic
components, allow a comfortable noise level both
inside and out. The noise level is comparable with
that of modern cars.
Maintenance features
