R 924 excavator is recommended for completely reliable
operation in all conditions.

Comfort

Another advantage of the R 924 is a space especially
created to satisfy the operator’s needs. The cab offers a
spacious, comfortable and quiet environment. Its ergo­nomics definitively enhances the operator’s performance.

Economy

A completely new maintenance concept reduces service
time on the new R 924. The grouping together of main­tenance components and accessibility from ground level
are aspects that make the excavator gain in productivity.
Return on investment is therefore guaranteed.

The Liebherr
Tool-Control System

A wide range
of equipment

The R 924 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 924.

The Tool-Control function makes it easy to change
tools thanks to recognition of the chosen tool’s sys­tem. It makes the programmed pressure and flow
values available from the moment the hydraulic tool
is changed. Consequently, the crawler excavator
has more availability for productive tasks, and ad­justment times are reduced.

The R 924 is an excavator adapted to all types of
works. The wide range of Liebherr tools and equip­ment available helps meet these needs. The different
sticks offered can, for example, be associated with a
straight gooseneck boom, a hydraulically-adjustable
boom, or an offset gooseneck boom. A hydraulic
quick-change attachment or Liebherr’s Likufix sys­tem are offered as options. These elements allow
fast and easy tool-changing.

Comfort

Another advantage of the R 924 is the space especially created to satisfy the
operator’s needs. The cab offers a spacious, comfortable and quiet environment.
Its ergonomics definitively enhances the operator’s performance.

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

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 weight­actuated height adjustor and its air-conditioning
with activated charcoal and built-in fan. It is espe­cially designed for the operators’ well-being.

To increase work comfort and productivity, the
acoustic power inside the operator’s cab is only
72 dB. The cab is mounted on viscoelastic rivets
that ensure the vibrations are fully absorbed. The
rubber flanges that support the pipes also actively
participate in reducing external noise.

All the controls are positioned so that the opera­tor can intuitively and accurately manipulate them.
The consoles on which the controls and manipula­tors rest are adjoined to the seat for optimal comfort
while working and more accurate movements.

A rear-space camera is fitted in the R 924 counter
weight. 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.
