During which process is the stability of the backhoe sometimes overloaded?

The process where the stability of the backhoe is sometimes overloaded is during the lifting operation. When the backhoe is engaged in lifting heavy loads, particularly when the load is positioned at a distance from the machine's center of gravity, it creates a significant moment that can compromise stability. If the load is too heavy or if the backhoe is not positioned correctly, there is a risk of tipping over. This highlights the importance of understanding weight limits and proper load handling techniques to maintain safety while operating heavy equipment.

In contrast, while material handling, trench digging, and using the extendible dipperstick can also present stability challenges, the act of lifting generally represents the most critical situation regarding stability overload, as it directly involves raising a load that changes the equipment's balance dynamically.
