[0002] Special purpose vehicles, also known as special-purpose vehicles, are vehicles equipped with specialized equipment or specially modified to undertake specific transportation (goods or personnel) or operational tasks. There are several ways to classify special purpose vehicles, one common method being based on structural characteristics into six main categories: box trucks, tank trucks, special-purpose dump trucks, stake-body trucks, crane trucks, and special structure vehicles.

[0003] The chassis is the base of a special-purpose vehicle, primarily serving a supporting and connecting function. It supports vital components such as the body, engine, transmission system, and suspension system, ensuring these components can be correctly installed and work together. Simultaneously, the chassis withstands various impacts and vibrations from the road surface, protecting the safety of the occupants and equipment. Currently, special-purpose vehicle chassis typically consist of longitudinal beams, crossbeams, and connecting components. These chassis come in several types, the most common including: side-beam chassis, spine chassis, and platform chassis.
