What is a “dynamic load” in rigging contexts?

In rigging contexts, a “dynamic load” refers to a situation where the load experiences changes in motion, meaning it may accelerate or decelerate during a lifting operation. This encompasses any load that is not static and could involve forces acting on the rigging equipment that vary over time, such as sudden movements, shifts in weight distribution, or external forces like wind or vibrations.

Understanding dynamic loads is crucial for safely planning and executing rigging operations, as they can impose additional stress on equipment and require careful calculations to ensure safety and stability throughout the lifting process. When comparing this to the other options, it becomes clear that a dynamic load is distinctly characterized by its variability in motion, unlike stationary or fixed loads that do not experience changes in movement.
