    ABSTRACT
    The title of this design is the structural design of the lifting and transportation trucks. Its purpose is to reduce production costs and improve production quality based on the original characteristics and performance of special purpose vehicles.
    The key to this design is to compare and analyze the solutions that can be adopted for the tailgate lifting devices of the lifting trucks, and to list the advantages and disadvantages of each solution, and finally select the optimal solution.
    The design has been based on a lot of information on the lifting trucks of the corrugated plate. It thoroughly analyzes the overall design of the structure design of the corrugated lifting transport vehicles. The most important part of the design is the selection of the chassis and the design of the lifting mechanism. Selection of hydraulic system and design of the tailgate device. The selection of the chassis model lays the foundation for determining the performance parameters of the vehicle. On this basis, the kinematics of the lifting mechanism was analyzed in detail, and the dimensions and parameters of each part of the lifting mechanism were determined and checked in detail to meet the standards. The purpose of the hydraulic system is to control each movable part to achieve lifting and loading of the goods. By calculating and selecting various hydraulic components, it is more accurate to determine the type of hydraulic components used in the system. Determined the general parameters of the hoisting truck. Analyze and calculate the performance of modified vehicles to determine whether they meet the requirements of national standards.
