The invention discloses a multi-purpose automobile, and relates to the technical field of automobiles. A fixed cross beam is installed on the position, close to a driving cab, of an automobile frame,a crane base and telescoping supporting foot is installed on the fixed cross beam, the side face of the crane base is connected with a longitudinal beam of the automobile frame through a crane longitudinal supporting plate, a crane is supported by the crane base and supporting foot in the working process, the crane hoists a self-unloading cargo compartment and up loads to conduct automatic replacing, and meanwhile cargos can be hoisted, loaded and unloaded; a front supporting table is installed on the position, close to the fixed cross beam, of the automobile frame, a plurality of middle supporting tables are installed in the middle, an overturning supporting table is installed at the tail end of the automobile frame, and the self-unloading cargo compartment or the rear ends of the other up loads are installed on the overturning supporting table; and a self-unloading hoisting device is installed on the front supporting table or the middle supporting tables, and the self-unloading hoisting device is connected with the self-unloading cargo compartment or the bottoms of the other self-unloading and removing type up loads through the front supporting table or the middle supporting tables. According to the multi-purpose automobile, achieving of rapid mounting and dismounting of the self-unloading cargo compartment or the other up loads is facilitated, meanwhile self-loading and self-unloading of the various cargos can be achieved, and the application range is wide.
