| Particulars | Liebherr R 992 Litronic | Liebherr R 978 SME Litronic |
|---|
The Liebherr R 978 SME Litronic and R 992 Litronic are both robust excavators designed for mining and heavy-duty engineering tasks. The R 978 has a smaller engine and lesser bucket digging force than the R 992 but compensates with a slightly lesser ground bearing pressure. The R 992 packs more power and larger bucket capacity suited for massive earthmoving projects.
Choosing between the R 978 SME Litronic and the R 992 Litronic depends on the project requirements. For projects that require more power and a larger bucket capacity, the R 992 is preferable. However, for operations that prioritize slightly better terrain adaptability and may benefit from a marginally smaller machine, the R 978 SME would be the better choice.
