What is likely to happen to a stacker if the ground at the loading site is sunken?

When a stacker is operated on sunken or uneven ground, it creates an imbalance that significantly affects its stability. The design of stackers relies on a stable surface to maintain equilibrium while lifting and transporting loads. If the ground is sunken, the stacker's center of gravity shifts, which can lead to a loss of stability.

In such scenarios, if the stacker is heavily loaded or improperly positioned, it may cause the stacker to capsize or tip over. This situation can be dangerous for the operator and can lead to damage to the stacker and any surrounding equipment or structures. Therefore, the inherent risk associated with operating on an unstable surface is why a sunken ground can lead to capsizing rather than improved stability or normal operation.
