The invention discloses a movable lifting device achieving hydraulic lifting. The movable lifting device comprises a cart base body and a manual hydraulic jack arranged on the cart base body. A square groove concave inwards is formed in the middle of the upper surface of the cart base body. The manual hydraulic jack is arranged in the square groove. A through hole corresponding to the bottom of the manual hydraulic jack is formed in the bottom of the square groove. The bottom of the manual hydraulic jack extends to the portion below the cart base body through the through hole. Hydraulic supporting rods extending upwards are arranged on the two sides of the square groove respectively. The ends of the hydraulic supporting rods are connected to the two sides of the manual hydraulic jack respectively. By means of the manner and the movable lifting device achieving hydraulic lifting, during lifting, the manual hydraulic jack is stressed to overcome the supporting force of the hydraulic supporting rods to descend, the bottom of the manual hydraulic jack is grounded, the bearing capability and lifting stability are improved, moving is flexible, and operation is convenient.
