The invention discloses a folding hydraulic climbing ladder for a semitrailer. Two fixed rib plates are welded on the left and right sides of the upper and lower ends of a front-section climbing ladder assembly, on the left and right sides of the lower end of a rear-section climbing ladder assembly and the left and right sides of the upper end of a tail plate assembly respectively; a central hole in the fixed rib plate at the upper end of the front-section climbing ladder assembly and a central hole in the fixed rib plate at the lower end of the rear-section climbing ladder assembly are aligned with each other, and a first pin shaft is inserted into the central holes; a central hole in the fixed rib plate at the lower end of the front-section climbing ladder assembly and a central hole in the fixed rib plate at the upper end of the tail plate assembly are aligned with each other, and a second pin shaft is inserted into the central holes; a climbing ladder supporting leg is further mounted on the first pin shaft and is positioned at the middle part of the first pin shaft; a plurality of climbing ladder anti-collision blocks are welded on the front-section climbing ladder assembly; an upright column oil cylinder is mounted on the front-section climbing ladder assembly. The folding hydraulic climbing ladder for the semitrailer is provided with the climbing ladder anti-collision blocks, so that collision between the front-section climbing ladder assembly and the rear-section climbing ladder assembly during transportation can be effectively prevented; the folding hydraulic climbing ladder for the semitrailer is simple in structure, reasonable in design, and safe and reliable in transportation.
