Closing Recommendation
Your choice between the Liebherr R 945 Litronic and Liugong 939E HD should be dictated by your specific requirements. If you need a heavy-duty excavator with higher bucket capacity and digging force for mining or similar projects, the Liebherr may be more suitable. However, for operations that demand higher engine horsepower, torque, and better performance on sloped terrains, the Liugong could be the better option. Consider the working conditions, material handling needs, and navigation requirements when making your decision.
