What risk can occur with a crane before any signs of tipping are evident?

In the context of crane operation, before any visible signs of tipping, a significant risk is that the crane can be overloaded. Overloading occurs when the weight of the load supports exceeds the crane's lifting capacity. This situation may not produce immediate visual indicators of instability, such as tilting or shifting, but it places immense stress on the crane's structure.

If a crane is overloaded, it can compromise the integrity of the crane's components, leading to potential failure. This risk can be particularly insidious, as operators may not become aware of the overload condition until it has reached a critical point, potentially resulting in accidents or structural damage.

While other potential risks exist, such as the failure of the boom or issues related to crane stability on uneven ground, these typically manifest in more apparent ways or under specific conditions. Similarly, the detachment of loads is a serious concern but generally is influenced by factors like improper rigging or excessive sway, rather than the original condition of the crane itself being inherently overloaded before showing signs of instability.
