Technology serving productivity
Liebherr Integration |
All the major components are designed and man- |
|
ufactured within the Liebherr group. This includes |
|
components such as the heat engine, hydraulic |
|
pumps, electronic components (injection mapping, |
|
hydraulic control, control console) and of course the |
|
essential mechanical elements including cylinders, |
|
the slewing ring and work tools, resulting in an over- |
|
all increase in productivity. |
Regeneration Plus |
The „Regeneration Plus“ function allows for the |
|
accelerated lowering of the boom, reduced losses |
|
of pressure and an improved work cycle. The opti- |
|
mization and combination of the „zero-pressure |
|
lowering of the boom“ and „Regeneration plus“ |
|
functions, together with the increased power of |
|
the hydraulics, provide increased performance and |
|
lower consumption. |
Power and speed
Increased |
Thanks to their kinematics and hydraulic power, the |
break-out force |
R 956 crawler excavators develop increased break- |
|
out and digging forces. The generously sized cyl- |
|
inders allow you to increase the break-out perfor- |
|
mance in hard materials. |
Faster cycles |
The mechanical link between the rotation engine |
|
and slewing ring gives the machine a high torque |
|
and swing speed, thus improving your operating |
|
cycles. |
Choice of work mode |
|
Floating Boom Function |
|
||
The different work modes offered allow you to adapt the power |
|
• Increased hydraulic flow for the |
of the excavator to the application |
|
other cylinders (stick and/or bucket |
E Mode - Economy: for economical and ecologically-friendly |
|
for example) |
|
|
|
operation. Minor restriction of power without affecting the load |
|
• More power available, making it easier |
lifting and excavating capacities. Highly recommended for light |
|
to extract materials and reduce work |
and moderate working conditions |
|
cycle times |
P Mode - Power: for high excavation capacities and difficult |
|
• Increased service life when a hydraulic |
applications. Pump flow and power are not limited |
|
hammer is used |
S Mode - Sensitivity: for precision jobs and loading of materials. |
|
|
The pump flow and power are restricted to attain optimal sensitivity |
|
|
P+ Mode - Full Power: especially designed for increased power; |
|
|
only recommended for extreme applications |

Reliability
Engineered for difficult operating conditions, the R 956 crawler excavators were designed to meet a list of specifications resulting from our customer’s requirements.
Fully-tested strength
Improved and reinforced With an X-shaped design and an increased slew-
undercarriage |
ing ring diameter, this new undercarriage is char- |
|
acterized by an even distribution of stresses over |
|
the whole structure. This results in increased per- |
|
formance, greater load properties and an increased |
|
service life. |
Safe travel |
The integration of 3 guiding guards per track as |
|
standard significantly reduces the risk of tracks |
|
coming off. In addition, track pins and bearings are |
|
lubricated for life, which reduces both maintenance |
|
tasks and down time. |
Strengthened |
The uppercarriage has been reinforced with heavier |
uppercarriage |
steel to ensure increased strength. The HD boom |
|
and stick are standard - improving resistance to the |
|
impact of materials. Similarly, the system of cast |
|
and welded housings on the boom allows for an |
|
improved distribution of stresses. |
Quality serving safety
Finest details |
The hydraulic, electric and lubrication lines are laid |
|
out to ensure optimum operating safety and maxi- |
|
mum availability. The finish paint applied before |
|
assembly and the appropriate surface treatment of |
|
the components guarantee maximum protection |
|
against corrosion. The integration of the rear camera |
|
in the counter weight elegantly highlights the overall |
|
perception of quality, safety and reliability. |
ROPS cab structure |
The cab is equipped with an integrated roll over |
|
protection system (ROPS), pursuant to standard |
|
ISO 12117-2. |

It’s just about feeling good
A spacious and ergo- |
The cab offers a generous space for maximum com- |
nomic work station |
fort. Equipped, among other things, with a pneu- |
|
matic seat with heater as standard (optional with air- |
|
conditioning), controls connected to the seat and |
|
high-performance automatic air-conditioning, the |
|
cab creates a pleasant working environment. All the |
|
controls are precisely laid out in an intuitive manner |
|
for greater responsiveness and concentration while |
|
working. The cab is mounted on viscoelastic studs |
|
for significantly lower vibration. |
Fully automatic |
The automatic air-conditioning with touchscreen |
air-conditioning |
controls has several ventilation outlets for optimum |
|
ambient air in the cab. |
High resolution |
The color touchscreen is a true human-machine |
color touchscreen |
interface for controlling several comfort functions, |
|
such as the radio, and more operational functions, |
|
such as work modes, tool types and even the |
|
backup camera. |
A cab that’s easy |
The possibility of working in a clean environment |
to look after |
was an important objective in the design of the cab. |
|
It is particularly easy to maintain thanks to elements |
|
such as a keyboard with soft touch comfort keys |
|
and an easily accessible cab air filter. |

Profitability
The raw performance amounts to maximum effective working hours. These excavators allow you to target essential operations and reduce operating costs in order to obtain the best return on investment.
The best choice
Low operating costs Thanks to its high technology and its innovation, the Liebherr France Company increases the performance of its machines while reducing their fuel consumption. Examples of this are the new diesel engine, automatic idling, electronic engine speed sensing control, Regeneration Plus function and the hydrostatic cooling system (fans operate only when necessary). Consequently, the reduced fuel consumption means less pollution.
LiDAT fleet and machine To improve your machine management, Liebherr park management tool has developed its own data transmission system using the GPRS network. This system allows you to instantly know the position of your excavator via a web interface. Thanks to data transmission, the LIDAT system developed and manufactured by
Liebherr keeps you informed about fuel consumption, number of service hours or machine faults, just to name a few. LIDAT allows you to be proactive and more responsive: organizing and maintaining your fleet for increased productivity.
Liebherr-Service
An excellent after-sales The after-sales services can be customized to suit service and respond to your specific needs. Several programs, such as ReMan, ReBuilt and Repair provide the perfect, economical solution, always including the manufacturer’s quality and guarantee. A team of technicians, specialized to intervene on your machines, has all the latest-generation diagnostic tools, for a reduced down time of the machine. By following your chosen maintenance program, you
