What occurs when the leverage from the load exceeds the leverage applied by the crane?

When the leverage from the load exceeds the leverage applied by the crane, a loss of stability occurs. Stability in cranes is primarily governed by the relationship between the weight of the load and the counterbalancing effects produced by the crane's own weight and its structure. If the load is positioned in such a way that it creates a greater moment (or leverage) around the crane's pivot point than the counteracting moment provided by the crane's base and operational setup, the crane can tip or become unstable.

This situation can happen, for example, when a load is lifted too far from the crane's center of gravity, increasing the risk of tipping over. Maintaining stability is crucial for safe operation; therefore, understanding how leverage affects stability helps prevent accidents and ensures that the crane is operated within its design limits.
