What is a load's "dynamic load"?

The concept of a load's "dynamic load" refers specifically to the additional forces and weight that a load experiences when it is in motion. This encompasses factors such as inertia, acceleration, and any other external forces that can act on the load while it is being lifted or moved.

When a load starts to move, particularly if it is stopped and then started again, it experiences forces that are not present when it is static. This dynamic effect can increase the stress on lifting equipment, so understanding the dynamic load is crucial for ensuring safety and maintaining the integrity of the lifting operation.

The other options do not accurately capture the essence of a dynamic load; they either refer to static weights or maximum capacity without considering the effects of motion and additional forces. Thus, the definition encapsulating the nature of motion and forces on a load is key to comprehending how dynamic loads impact lifting practices.
