|---|
The Liebherr R 978 SME Litronic and Komatsu PC800-8R are both heavy-duty excavators designed for mining and construction. The Liebherr boasts a standard AC cabin and larger bucket capacity, while the Komatsu features higher engine power and better gradeability.
The choice between the two models should be based on specific job requirements. If priority is given to cabin comfort and load capacity, the Liebherr R 978 SME Litronic could be the better choice. However, for higher performance, more challenging terrains, and operational reach, the Komatsu PC800-8R appears more equipped to handle such demands.
