What is the difference between static and dynamic lifting?

The distinction between static and dynamic lifting is fundamental in the context of rigging and material handling. Static lifting refers to the act of handling a load that is at rest, meaning that the load is stationary and does not change its position during the lift. This type of lifting typically involves the application of force to hold or support a load that is not in motion, allowing for controlled handling without the influence of additional factors such as acceleration or velocity.

On the other hand, dynamic lifting involves loads that are in motion or are subjected to acceleration. This type of lifting can occur when the load is being moved from one location to another or when it is being manipulated in such a way that it is not stable. The forces acting upon dynamic loads can vary due to acceleration, deceleration, or changes in direction, making the handling of dynamic loads more complex compared to static loads. This understanding of the differences helps riggers to plan and execute lifts safely, accounting for the specific forces at play during each type of maneuver.
