What factor is a common cause of stackers rolling over?

Stackers rolling over is often linked to the combination of speed and the height of the stockpile being managed. When the speed of the stacker is too fast while attempting to move or stack loads that are too high, it creates a higher risk of instability. The center of gravity becomes more elevated and less stable, particularly when navigating corners or making abrupt maneuvers. This situation can easily lead to a loss of control, resulting in a rollover.

In contrast, while low battery levels, uneven ground surfaces, and faulty brakes can contribute to safety issues, they do not directly create the dynamic instability that arises from excessive speed combined with high loads. Therefore, focusing on speed management and ensuring loads are within safe stacking heights is crucial for preventing rollovers in stackers.
