World mining and building tools big Liebherr lately rolled out its first-ever battery electrical crawler excavator, setting a brand new normal in heavy earth-moving tools capabilities with low noise ranges and nil native emissions.
Liebherr has made headlines within the sustainability house with its huge electrical haul vehicles and stupefyingly fast 6MW cryo-cooled DC quick chargers, however its typical mid-sized tools strains haven’t electrified as rapidly, leaning as an alternative on hydrogen combustion and gas cell efforts. That appears to be altering, nonetheless, 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 info 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, corresponding to in cities or underground working places.
Regardless of the shortage of pleasure within the launch copy, there may be numerous pleasure in regards to the R 920 G8-E’s progressive new management cab philosophy.
Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USer Interface), the system integrates clever management logic with superior machine studying capabilities to provide operators a extremely customizable interface that may comply with them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the educational curve for operators on a given job website.
Liebherr says INTUSI improves each operational effectivity and consumer consolation on Liebherr job websites by the mixing of quite a lot of new options. From the press launch:
- Haptic suggestions – vibrations alert the operator to crucial circumstances—corresponding to reaching dynamic machine 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 12 months, as a proof of idea co-developed with world mining giants Fortescue as they put money into new expertise to decarbonize their mines.
Since then, Fortescue has used the machine to maneuver tens of millions of tons of grime, and has ordered a number of extra. And, as a result of every thing from excavators to loaders to heavy vehicles are constructed to be powertrain agnostic, and producers will typically provide the identical fundamental 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 rather than an inner combustion engine, and I anticipate this excavator would be the first of many such machines from the model.
