R 920 Litronic

Performance

Liebherr’s R 920 combines power, precision and versatility. Its characteristics

guarantee its excellent performance in a wide variety of applications, including

the toughest. And its movements attain an unequalled level of smoothness and

precision thanks to the latest generation hydraulic system. The R 920 is therefore

suitable for both light and heavy daily tasks. The dozing blade, a key feature of

this excavator, is added to a vast range of tools and undercarriages which make

it essential.

Liebherr integrated systems engineering

Cutting-edge technology

for high performance

The R 920 excavator incorporates Liebherr’s Positive

Control hydraulic system. This system is controlled

by Liebherr electronics and uses strategically-posi-

tioned 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 sepa-

rately or together, this optimises the energy manage-

ment of the R 920.

Harmony between versatility and power

From power

to performance

The excellent productivity and high performance

of the R 920 are the results of intense research. In

particular, this machine has a clean and efficient

105 kW engine that complies with the requirements

of the new Stage IIIB regulations on exhaust gas

emissions. The optimal kinematics of the attach-

ments allows the R 920 to reach a break-out force

of 126 kN and a penetration force of 99 kN, while

simultaneously increasing its lifting force.

The Liebherr

Tool-Control System

The Tool-Control function makes it easy to change

tools thanks to recognition of the chosen tool’s sys-

tem. 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 ad-

justment times are reduced.
