Performance
Thanks to its innovative Advanced excavator system
technology, the R 946 crawler excavator has performance
features that are truly unique. Characteristic elements of
this system technology include the particularly effective
and energy-efficient Positive Control twincircuit hydraulic system, which was specifically designed for machines
with a high level of superimposed functions and operational movements. The electronic pump control arrangement sets this technology apart, creating a new standard
for performance and quantity control that entirely matches the operator’s needs.

Liebherr provides customers with solutions that lead the
way for the future, solutions for maximum equipment
reliability and availability, solutions which satisfy the
most extreme demands for performance and quality.
With more than 50 years experience in the construction
of hydraulic excavators, we have an advantage in design
and consultation that clearly sets us apart.
Comfort
In the cab the driver can look forward to a workplace
designed in accordance with the very latest findings in
ergonomic science, with emphasis on comfort and ease
of operation. The optimised arrangement of the hydraulic hoses means that the driver has en even wider field of
vision, and the heating and climate control system fitted as
standard means pleasant working conditions inside, whatever the weather. Liebherr crawler excavators are also particularly easy to service – maintenance tasks can be carried
out easily and rapidly at readily accessible service points.
Economy
Crawler excavators from Liebherr guarantee maximum
productivity. The optimum interplay of hydraulics and
electronics means that individual movements and superimposed movements alike can be carried out particularly
efficiently. And, perhaps last but by no means least, the
perfect harmonisation of all the components means that
energy expenditure during operation can be kept to an
absolute minimum.

Performances
Thanks to its innovative excavator system technology, the R 946 crawler excavator has performance features that are truly unique. Characteristic elements
of this system technology include the particularly effective and energy-efficient
Positive Control twin-circuit hydraulic system, which was specifically designed for
machines with a high level of superimposed functions and operational movements.
The electronic pump control arrangement sets this technology apart, creating
a new standard for performance and quantity control that entirely matches the
operator’s needs.

High-tech for high
performance
Positive Control

system
Power and speed
Faster work cycles
Among the high-tech equipment on the Advanced
version of the R 946 is the newly-developed integrated excavator system technology. This is based on
the Positive Control hydraulic system, controlled by
Liebherr electronics and the system software. The
sensors located at strategic points on the machine
form the basis for an intelligent system that allows for
fast and fluent working.
When travelling straight or in a curve, and during
levelling work, the two pump circuits of the hydraulic system are separated or grouped together, as the
need arises. Separation of the systems means that
different consuming components can be supplied
with different load pressures independently, and
saving energy too. By contrast, grouping the pump
circuits allows for maximum speeds with individual
or superimposed movements, and that means optimum energy utilisation.
The R 946 achieves particularly fast work cycles,
thanks, for example, to the powerful slewing drive of
the superstructure, the rapid slewing rates, and the
creation of high slewing torque.
Wide range of operational
possibilities
• Large number of equipment variants
• Versatile selection of undercarriage
variants
• Broad operational spectrum, from
earthmoving, to grading work, to
demolition
Operating
pressure
With an operating pressure of 380 bar, the R 946
achieves higher hydraulically limited load capacities and higher digging forces, of up to 229 kN,
and break-out forces of up to 238 kN; perfect for
more difficult operational situations such as canal
or pipeline construction.

Reliability
Liebherr provides customers with solutions that lead the way for the future,
solutions for maximum equipment reliability and availability, solutions which
satisfy the most extreme demands for performance and quality. With more than
50 years experience in the construction of hydraulic excavators, we have an
advantage in design and consultation that clearly sets us apart.
High stability undercarriage
Better force distribution
The undercarriage concept leads to increased performance with improved service life. Thanks to the
connection of the middle section being extended as
far as the ends of the chassis beams, known as the
X-design, the forces are better distributed, which
increases the service life of the undercarriage.
Technology with perspective
Quality right down
to the last detail
Perfect optimisation
The at-a-glance layout of the hydraulic, lubrication,
and electricity lines makes for optimum functional
reliability and maximum availability of the unit. Best
possible corrosion protection is guaranteed thanks
to components and modules being finalpainted and
surface treated before assembly.
Individual components of the drive train, manufactured in-house, such as diesel engine, traction drive,
rotary actuators, operating pump and hydraulic
cylinder are perfectly optimised with one another.
As components of a total system designed for long
operational life, they guarantee maximum possible
reliability.

Height Can be slewed though 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity
The lift capacities on the load hook of the Liebherr quick coupler 66 without attachment are stated in metric tonnes (t), and can be lifted 360° on
firm, level supporting surface. Adjacent values are valid for the undercarriage when in the longitudinal position. Capacities are valid for 600 mm
wide triple-grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated by *) or are limited through the allowed lift capacity of the load hook on the quick coupler (18 t). Without quick coupler the lift capacities will
increase by 450 kg, without bucket cylinder, link and lever they increase by an additional 625 kg.
According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.

Height Can be slewed though 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity
The lift capacities on the load hook of the Liebherr quick coupler 66 without attachment are stated in metric tonnes (t), and can be lifted 360° on
firm, level supporting surface. Adjacent values are valid for the undercarriage when in the longitudinal position. Capacities are valid for 600 mm
wide triple-grouser pads with adjusting cylinder in optimal position. Indicated loads are based on ISO 10567 standard and do not exceed 75 %
oftipping or 87 % of hydraulic capacity (indicated by *) or are limited through the allowed lift capacity of the load hook on the quick coupler (18 t).
Without quick coupler the lift capacities will increase by 450 kg, without bucket cylinder, link and lever they increase by an additional 625 kg.
According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.

Height Can be slewed though 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity
The lift capacities on the load hook of the Liebherr quick coupler 66 without attachment are stated in metric tonnes (t), and can be lifted 360° on
firm, level supporting surface. Adjacent values are valid for the undercarriage when in the longitudinal position. Capacities are valid for 600 mm
wide triple-grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated by *) or are limited through the allowed lift capacity of the load hook on the quick coupler (18 t). Without quick coupler the lift capacities will
increase by 450 kg, without bucket cylinder, link and lever they increase by an additional 625 kg.
According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.

Height Can be slewed though 360° In longitudinal position of undercarriage Max. reach * Limited by hydr. capacity
The lift capacities on the load hook of the Liebherr quick coupler 66 without attachment are stated in metric tonnes (t), and can be lifted 360° on
firm, level supporting surface. Adjacent values are valid for the undercarriage when in the longitudinal position. Capacities are valid for 600 mm
wide triple-grouser pads. Indicated loads are based on ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity (indicated by *) or are limited through the allowed lift capacity of the load hook on the quick coupler (18 t). Without quick coupler the lift capacities will
increase by 450 kg, without bucket cylinder, link and lever they increase by an additional 625 kg.
According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.

wide triple-grouser pads with adjusting cylinder in optimal position. Indicated loads are based on ISO 10567 standard and do not exceed 75 %
oftipping or 87 % of hydraulic capacity (indicated by *) or are limited through the allowed lift capacity of the load hook on the quick coupler (18 t).
Without quick coupler the lift capacities will increase by 450 kg, without bucket cylinder, link and lever they increase by an additional 625 kg.
According to European Standard, EN 474-5: In the European Union excavators have to be equipped with an overload warning device, a load diagram and automatic check valves on the hoist cylinders, when they are used for lifting operations which require the use of lifting accessories.
