What is a major effect of abruptly stopping a rapid swing on a long-boom mobile crane?

Abruptly stopping a rapid swing on a long-boom mobile crane can lead to a significant risk of overturning the crane or collapsing the boom. This occurs because the sudden cessation of motion generates a high level of dynamic forces that can exacerbate existing stresses on the crane's structure. Long-boom cranes are particularly susceptible to these effects due to their extended reach, which increases leverage and can shift the crane’s center of gravity. The abrupt halt can result in an unbalanced load. If the load is swinging and suddenly stopped, it can cause a rapid shift in weight distribution, further contributing to the risk of the crane tipping over or the boom failing under the unexpected load dynamics. Understanding these effects is essential for safe crane operation and to prevent accidents on site.
