What type of load is affected by acceleration during lifting?

A dynamic load is one that changes in response to movement, acceleration, or other forces acting on it. When lifting a load, acceleration can significantly influence the behavior of the load—both the kinetic energy and the forces exerted on the rigging and lifting equipment. This means that during the lifting process, if the load accelerates, the force on the rigging setup can increase, which must be accounted for in calculations for safety and efficiency.

In contrast, static loads remain constant and do not change over time; they do not fluctuate with lifting or movement. Minimum and constant loads also refer to different scenarios—minimum load typically pertains to the least amount of load that can be safely handled or supported, while constant load refers to a consistent force that does not change. Therefore, when focusing on loads that are specifically influenced by acceleration during a lift, dynamic loads are the relevant category.
