Dynamic factor lifting
WebA dynamic load is any load that changes over time. These type of loads exert forces onto a structure that are often much greater than their static equivalents. For example, someone jumping up and down will exert a greater force on the floor than someone standing still. Causes of dynamic loading can include anything from people moving around to ...

WebMar 31, 2024 · With a dynamic load, some outside factor causes the forces of the weight of the load to change. Some of the factors that can affect a load and make it dynamic include: Movement: If the holder of a load is in motion, chances are that the force created by the weight distribution could change.
