Closing Recommendation
If the requirement is for deeper and more powerful excavation tasks, and the work environment allows for a larger machine, the Sany SY500C-10HD may be the better option. However, if operating on softer grounds and needing flexibility with bucket sizes, along with better maneuverability in tighter spaces, the Liugong 950E could be more suitable. Evaluate the specific needs of the tasks at hand, including space constraints and the nature of the ground, before making a decision.
