Liebherr-France SAS has introduced the R 920 G8-E, the company’s first battery-powered electric crawler excavator.
Liebherr-France SAS is the global development centre of the Liebherr Group for crawler excavators for earthmoving. The new electric crawler excavator completes the product range of Liebherr crawler excavators produced in Colmar, France.
The R 920 G8-E has the same capabilities as a conventional, diesel-powered crawler excavator and features particularly low noise levels and zero emissions. The excavator is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.
The R 920 G8-E electric excavator features a new drive and a long operating time.
In addition to local, zero-emission operation, the electric drive enables high continuous output and maximum energy efficiency on the building site. The R 920 G8-E has a high-voltage battery with a capacity of 188 kWh (standard) or 282 kWh (high capacity). The machine can be charged at up to 150 kW direct current or 44 kW alternating current.
Depending on the application, the R 920 G8-E achieves an operating time of six to eight hours without intermediate charging. It increases to 10 hours with a one-hour intermediate charge at 150 kW.
INTUSI operating concept
The electrical drive ensures improved noise levels, both for the driver and in the vicinity of the machine. The R 920 G8-E crawler excavator also features a completely new operator’s cab with a futuristic design. Large windows ensure a great view and improve safety. Furthermore, the new, large and ergonomic cab offers a wide range of convenient equipment and a large storage compartment.
The intuitive operating concept, INTUSI, can be adjusted to the user’s requirements, which in turn makes the operator’s work easier.
The modern operating environment ensures a special user experience and enables efficient, productive and convenient work. With numerous integrated assistance systems such as the 3D machine controller, the weighing device or the Skyview 360-degree camera, the R 920 G8-E is equipped for all building sites and applications.
Liebherr displayed the R 920 G8-E with an output of 115 kW, an operating weight of 20,900 kg and a 0.7-cubic-metre ditch cleaning bucket at bauma.
