What is the role of the side panels in terms of payload capacity?

The role of the side panels in terms of payload capacity primarily relates to load management. Side panels are integral to ensuring that loads are not only secured but also distributed appropriately within the container. Effective load management involves preventing overloading in specific areas, ensuring that the cargo does not shift during transit, and maintaining the overall stability of the load. This contributes to maximizing the usable capacity of the dry van without exceeding the structural limits of the equipment or risking damage to the cargo itself.

While structural support is essential for the integrity of the container, it is primarily the design and material of the side panels that facilitate load management. Weight distribution is more closely associated with how loads are placed and balanced rather than the panels themselves, while height adjustment is not relevant in this context as side panels do not typically allow for alterations in height. Therefore, the correct answer focuses on how the side panels play a critical role in managing loads effectively, which directly influences the capacity that can be safely utilized.
