During the trade fair in Shanghai Liebherr exhibits the new R 920 crawler excavator. The 21-tonne machine was especially developed for use in earthmoving, digging and drainage / sewerage work and has an output of 110 kW / 150 HP. The concept of the Liebherr R 920 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.
In April, the market launch of the R 920 was accompanied by a complete renewal of all crawler excavator models for less regulated markets between 20 tonnes and 25 tonnes. In addition to the R 920, this product programme also includes the models R 922 and R 924 with operating weights of 22 tonnes and 24 tonnes respectively and outputs of 110 kW / 150 HP and 125 kW / 170 HP.
Comfort and performance for efficient usage
Liebherr enhanced the comfort for the driver in the new series. For instance, the R 920 has newly designed seats, a 7" touch screen and larger windows. This gives the driver a better view of the working environment, thus increasing work safety.
In addition, the optimised Positive Control hydraulic system makes the combined movements of the machine even more fluid, which in turn increases the breakout forces and breakaway torques. The largest fuel tank available on the market, which is part of the equipment of the R 920, as well as the bigger attachments available as optional equipment, permit efficient usage.
