The R 926 excavator is fitted with Liebherr’s Posi­tive Control hydraulic system. This system is con­trolled by Liebherr electronics and uses strategi­cally-positioned sensors. All of the machine’s work
is therefore faster, more accurate and fluid. What’s
more, as the two hydraulic pump circuits can oper­ate either separately or in unison, this optimises the
energy management of the R 926.

The excellent productivity and high performance
of the R 926 are the results of intense research. In
particular, this machine has a clean and efficient
129 kW engine that complies with the requirements
of the new Tier 4i/stage IIIB regulations on exhaust
gas emissions. Maximum performance is also pos­sible in situations that require it thanks to through
high-torque rotary dampers and a high lifting power.

ommended for work sites requiring high productiv­ity. The R 926 excavator is perfectly suited to dif­ficult tasks such as earthworks or feeding a mobile
crusher.

A 380 bar operating pressure, a balance between
power and speed, all these advantageous factors
contribute to significantly increasing the number of
work cycles on a work site, in even the most dif­ficult applications.

The R 926 crawler excavator is a product de-

parts strengthen the excavator at strategic points
for difficult applications.

The cab is fitted with a roll-over protection sys­tem, which allows the operator to work in the saf­est possible environment.

The strength of the undercarriage lengthens the
service life of the machine. Liebherr-France SAS
selects high quality materials for building the
undercarriage and can meet the needs of all its
customers by offering a large variety of X-shaped
undercarriages. Furthermore, the larger openings
between the track carriers and the central part of
the undercarriage do make them easier to main­tain, as do the steps on the vertical side of the
track carriers.

Liebherr-France SAS is ISO 9001 certified. The
quality process begins with the design of the
product and ends with its manufacture. This
leads, as an example, to the selection of the
best materials on the market. Then several in­spections are regularly carried out during the
manufacturing process to fulfill this quality ob-

jective.

Comfort

One of the advantages of the R 926 is a space especially created to satisfy
the operator’s needs. The cab provides a spacious, comfortable and quiet
environment. This aspect of well-being enhances the operator’s performance.

In this cab, operators have a pneumatic seat, an en­larged space and an environment with all comforts.

Depending on the operator’s needs, the Liebherr

Premium seat can be chosen as an option. This
seat offers maximum seating comfort thanks to its
pneumatic lumbar support, its electronic weight-

with activated charcoal and built-in fan. It is espe­cially designed for the operators’ well-being.

All the controls are positioned so that the opera­tor can intuitively and accurately manipulate them.

A rear-space camera is fitted in the R 926 counter­weight. A display on the 7” high resolution screen
allows the operator to work in a secure area. This
complete visibility gives the operator full confi­dence in the tasks they perform.

The proportional control allows a very fine manoeu­vrability for a sensitive, accurate and more fluid
operation of hydraulic tools. The sensitive manipu­lator with proximity switch allows greater respon­siveness while resuming rpm.
