When choosing a cargo box for an off-road truck chassis, there are far more factors to consider than just the size and capacity of the box. In order to ensure that the cargo box can give full play to its function, while ensuring driving safety and efficiency, we need to make comprehensive consideration from the following aspects.

First, it is important to have a clear understanding of the carrying capacity of the chassis, including the maximum total mass and axle load distribution. The weight of the cargo box and the total weight of the loaded goods should not exceed the carrying capacity of the chassis, otherwise it may lead to driving safety hazards.

The size of the cargo box should be determined according to the specific loading requirements. If it is often necessary to load large goods, then the length, width and height of the cargo box should be increased accordingly. At the same time, the internal structure of the cargo box should also be designed according to the characteristics of the goods, such as the need for partitions, hooks and so on.

Off-road trucks often need to drive in complex road conditions, so the material of the cargo box should have enough strength and durability. Aluminum alloy cargo box is lightweight, but may not be suitable for use in extreme road conditions; while steel cargo box is heavier, but its strength and durability is better.

The design of the cargo box should facilitate the loading and unloading of goods. For example, the tailgate of the cargo box can be designed as an open type, which is convenient for the operation of forklifts and other equipment; the interior of the cargo box can be designed with sliding rails, which is convenient for the movement of goods.

Finally, the selected cargo box must comply with relevant national regulations and standards, including size, load, safety and other requirements. A non-compliant cargo box may not only lead to fines, but also affect driving safety.
