Transport of goods and cargo has great economic importance in today's society. The need for the transportation of various goods has arisen since the distant past, and the development of transport vehicles is progressing accordingly. Whether it's minerals, agricultural products or construction materials, the efficiency of transporting bulk materials is critical to sustaining global supply chains and to support economic activities. The topic of this paper is the design and construction of tipping body with a crane for the N1 category vehicles. Before designing, it is necessary to consider the types of trucks and existing superstructures, as well as the applicable legal regulations. After the selection of the truck and chassis, guided by the requirements that the upgrade must meet, the stages of conception and selection of structural solutions begin. These stages include the shaping of the frame and cargo box, the connection of the frame and chassis of the truck, and the shaping of the connection with the crane. The calculation of the strength of the structure, the axle load of the vehicle and the stability of the vehicle when using the crane was carried out. At the end, the final amount of the truck's carrying capacity is given. The work was accompanied by the creation of a 3D model of the upgrade and technical documentation.
