Which type of cargo requires diagonal securement?

Diagonal securement is particularly important for large, flat items such as sheets of plywood because of their size and shape. When these items are secured diagonally, it helps to distribute the forces exerted during transport more evenly across the cargo. This technique prevents the items from sliding or shifting, especially when making turns or sudden stops.

Large, flat items can easily tip or become unstable if they are not secured properly. Diagonal strapping allows for greater stability, reducing the risk of movement that could lead to accidents or damage. This form of securement effectively uses the tension in the straps to hold the items in place against the forces acting on them while the vehicle is in motion.

In contrast, other types of cargo such as small, irregularly shaped items, heavy machinery, and cylindrical objects may require different securement methods that are more suited to their specific characteristics and needs. For example, small items often require block-and-brace techniques, while heavy machinery might need chains or tiedowns that can hold their weight securely. Cylindrical objects typically require securement methods like cradling to ensure they do not roll during transit. Therefore, diagonal securement is specifically advantageous for large, flat items.
