The invention discloses a light-weight semitrailer frame and a semitrailer. The semitrailer frame comprises a bottom frame, a plurality of side plates, two suspension connecting parts and a plurality of inclined stand columns. The side plates are fixedly arranged above the bottom frame, and the side plates located on the left side and the right side of the bottom frame are obliquely arranged. The bottom frame comprises two longitudinal girders located on the left side and the right side and a plurality of connecting cross beams used for connecting the two girders. The two suspension connecting parts are located below the portions, close to the tail ends of the vehicle, of the two girders respectively, each suspension connecting part and the corresponding girder are fixed into a whole, and each suspension connecting part is located on the inner side of the corresponding girder. The overall shape of each inclined stand column is a triangle with a notch, the notch is located at one corner of the triangle, the inclined stand columns are welded and fixed to the girder at the notches, and the two adjacent edges at the notches are welded and fixed to the side plates which are obliquely arranged and the side faces of the suspension connecting parts respectively; each connecting position of the hanging connecting part is located on the inner side of the bottom end of the inclined stand column.
