The invention relates to a hydraulically-driven foldable lifting drive platform. The hydraulically-driven foldable lifting drive platform comprises a foundation underframe, a foldable frame, conveying frames and a universal wheel carrier. The foldable frame is mounted on the foundation underframe and comprises a driving mechanism formed by meshing of lead screws with nuts, and a motor drives the lead screws to rotate to further drive the nuts which are fixedly mounted on one side of the foldable frame, so that ascent and descent of the foldable frame are achieved. Fixed frames are fixedly mounted at the upper end of the foldable frame, wheel blocking rows are fixedly mounted at two side edges of the fixed frames parallelly, and the conveying frames slide between the wheel blocking rows. The universal wheel carrier is mounted on the fixed frames between the conveying frames and is driven to ascend and descend by a hydraulic cylinder fixedly mounted on the fixed frame, universal wheels are arranged on the universal wheel carrier at intervals, and the conveying frames are pulled on the fixed frames, at rear ends of two sides of the conveying frames, through hooks. The hydraulically-driven foldable lifting drive platform has the advantages that a lifter of the lifting drive platform is of a foldable frame type structure, the foldable frame is driven by a motor-lead screw system, and the lifting drive platform is reliable in action, small in overall size and high in drive efficiency.
