When the crane is configured over-the-side, what is the effect on the center of gravity?

When a crane is configured over-the-side, the effect on the center of gravity is that it can shift either closer to or farther away from the tipping axis depending on various factors, including the load being lifted and its position relative to the crane's structure. This configuration involves extending the boom to the side, which changes the distribution of weight and the dynamics of the crane.

As the boom extends over the side, the load's position relative to the center of gravity can vary. If the load is positioned closer to the base or center of the crane (the tipping axis), the center of gravity may shift closer to that axis, enhancing stability. Conversely, if the load is extended further away from the crane or the tipping axis, the center of gravity can shift farther away, increasing the risk of tipping.

The ability for the center of gravity to move in both directions is critical for crane operators to consider, as it directly impacts the stability and safety of the lift operation. Understanding this dynamic helps ensure that proper precautions are taken to maintain balance and prevent accidents.
