Question: 1 / 400

What is "load swing" in the context of crane operations?

The rotational force of the crane

The pendulum effect of a load being lifted

In crane operations, "load swing" refers to the pendulum effect that occurs when a load is lifted and begins to move sideways due to inertia or external forces, such as wind. Once the load is lifted off the ground, any slight movement or force can cause it to swing, similar to how a pendulum moves back and forth. This movement can impact the precision of the load placement and poses a risk if not managed properly, as it can lead to swinging into obstacles or even an unsafe condition for the crane.

Understanding load swing is critical for operators, as they must account for it during lifting operations to ensure safety and efficiency. Operators are trained to execute maneuvers that minimize swing, such as being cautious with input to the controls and making smooth, gradual movements. This knowledge is paramount to maintaining control of the load during transportation and placement.
