The invention discloses a novel low flatbed semitrailer folding ladder stand and a low flatbed semitrailer, the folding ladder stand comprises a first ladder stand section and a second ladder stand section, one end of the first ladder stand section is hinged to the tail of the low flatbed semitrailer, the other end of the first ladder stand section is hinged to the second ladder stand section, and the first ladder stand section and the second ladder stand section can be folded together or unfolded to a plane. A crawling ladder supporting device is further arranged at the tail of the low-flatbed semitrailer, the free end of the second crawling ladder section can be in lap joint with the crawling ladder supporting device and serves as an inclined support of the first crawling ladder section so that the first crawling ladder section can be kept in a horizontal state, and when the first crawling ladder section is kept in the horizontal state, the top face of the first crawling ladder section is flush with the top face of a cargo carrying platform of the low-flatbed semitrailer. And the bearing surface serves as an extended bearing surface of the cargo carrying platform. The low flatbed semitrailer comprises a frame, a walking mechanism, a cargo carrying platform and the folding ladder stand. The ladder stand has the advantages that wind resistance can be reduced, the included angle between the ladder stand and the ground can be reduced, the length of the cargo carrying platform can be increased, and the loading efficiency is improved.
