World première at Bauma 2016

The Liebherr R 922 crawler excavator for less regulated markets

In Munich, Liebherr presented a new crawler excavator model series, whose diesel engines satisfy the emissions standards Stage IIIA / Tier 3 / CHINA III.

As a world première Liebherr presented the new crawler excavator R 22. The demonstration model was equipped with a 5.7 m monoblock boom and 2.9 m dipper arm, as well as a 1.15 m³ backhoe bucket. Its LC travel mechanism is 2 380 mm wide. The 22-tonne machine was developed especially for use in earthmoving, digging and drainage/sewerage work and has an output of 110 kW/150 hp. The concept of the Liebherr R 922 is based on European standards and aims to improve reliability, as well as generate even higher productivity on the construction site – with lower fuel consumption at the same time.

The market launch of the R 922 is accompanied by a complete renewal of all crawler excavator models for these markets between 20 and 25 tonnes. In addition to the R 922, this also includes the models R 920 and R 924 with operating weights of 21 and 24 tonnes respectively and outputs of 110 kW/150 hp and 125 kW/170 hp. The robust travel mechanism, the optimized Liebherr tooth system Z for attachments, as well as the optional backhoe bucket in a heavy-duty version, ensure long and efficient use of the new crawler excavator.

With a new maintenance concept Liebherr was able to reduce the costs of excavator maintenance. For instance, with the R 922 the maintenance elements are positioned close together and are easily accessible from the ground. The automatic central lubrication system is installed as standard and leads to increased productivity resulting from time savings.
