|---|
The Liebherr R 978 SME Litronic and the Komatsu PC850-8R1 are two heavy-duty excavators designed for mining and large-scale construction projects. The Liebherr model boasts a slightly stronger bucket digging force and a large fuel tank, while the Komatsu model provides a higher engine power and an impressive gradeability.
When deciding between the two, you may want to consider the specific requirements of your work site. If higher engine power and the ability to work on steep terrains are critical, the Komatsu PC850-8R1 may be more suitable. However, if you prioritize bucket digging force and fuel capacity, the Liebherr R 978 SME Litronic will be the better option. Evaluate the pros and cons based on your operational needs and site conditions for an informed decision.
