International mining and building tools big Liebherr lately rolled out its first-ever battery electrical crawler excavator, setting a brand new customary in heavy earth-moving tools capabilities with low noise ranges and nil native emissions.
Liebherr has made headlines within the sustainability area with its huge electrical haul vehicles and stupefyingly fast 6MW cryo-cooled DC quick chargershowever its typical mid-sized tools traces haven’t electrified as rapidly, leaning as an alternative on hydrogen combustion and gasoline cell efforts. That appears to be altering, nevertheless, with the launch of the 20-ton R 920 G8-E – the model’s first-ever manufacturing unit recent Hdev.
The corporate’s official copy is characteristically low-key, with an emphasis on the information and options as an alternative of hype:
The brand new mannequin completes the product vary of Liebherr crawler excavators produced in Colmar (France). It’s notably quiet and emission-free. It generates the identical output as a diesel machine in the identical class and is especially appropriate for constructing websites that require low noise ranges and avoiding exhaust fuel emissions, akin to in cities or underground working areas.
Regardless of the dearth of pleasure within the launch copy, there may be a whole lot of pleasure concerning the R 920 G8-E’s revolutionary new management cab philosophy.
Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USis Interface), the system integrates clever management logic with superior machine studying capabilities to present operators a extremely customizable interface that may observe them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the training curve for operators on a given job website.
Liebherr says INTUSI improves each operational effectivity and person consolation on Liebherr job websites by way of the combination of numerous new options. From the press launch:
- Haptic suggestions – vibrations alert the operator to important circumstances—akin to reaching dynamic gadget limits—enhancing situational consciousness and rushing up response instances.

Electrek’s Take
If the notion of a battery electrical Liebherr excavator appears acquainted, that’s as a result of it ought to – the corporate first transformed one in all its ultramassive R9400 mining excavators final yras a proof of idea co-developed with world mining giants Fortescue as they put money into new know-how to decarbonize their mines.
Since then, Fortescue has used the machine to maneuver hundreds of thousands of tons of grime, and has ordered a number of extra. And, as a result of every little thing from excavators to loaders to heavy vehicles are constructed to be powertrain agnostic, and producers will typically provide the identical primary automobile with Cummins, Detroit Diesel, or Volvo energy, so there’s a level of openness baked into these programs already. Liebherr is simply taking that to the following stage by putting in an electrical drive motor instead of an inner combustion engineand I anticipate this excavator would be the first of many such machines from the model.
