Liebherr R 956 - Manual (Page 7)

7 R 956 Litronic
Reliability
Undercarriage
• New design for increased life and
improved distribution of forces
• Linear slope between the upper plate of
the central section and the track carriers
for constant cleaning
• Easy and safe transport thanks
to integrated securing hooks
• 3 types of undercarriage available,
including one with a variable gauge
for an accurate configuration to suit
the jobsite requirements
Key components developed by Liebherr
• Perfect harmonization of the machine
elements, designed specifically for
earthmoving and quarry applications
• Engine, hydraulic pumps, transfer box,
transmission, rotating mechanism, slewing
ring, cylinders and electronic components
are designed and manufactured by Liebherr
• Purpose built options such as special at-
tachment lengths
• Specific tools and custom protection can
be added at the factory
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
undercarriage
With an X-shaped design and an increased slew-
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
uppercarriage
The uppercarriage has been reinforced with heavier
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.
