The invention discloses a foldable gantry lifting device. The foldable gantry lifting device comprises a foldable gantry and a lifting device, the folding door frame comprises a frame, a frame overturning mechanism, a plurality of supporting legs and a supporting leg rotating mechanism. The frame is formed by splicing two fixed beams and two folding beams, the folding beams are parallel to each other, and each folding beam comprises a first branch beam and a second branch beam which are hinged to each other; the frame turnover mechanism is used for providing power, so that the first supporting beam and the second supporting beam are mutually folded or unfolded; the supporting legs are hinged to the frame, and the supporting leg rotating mechanism is used for providing power to enable the supporting legs to rotate; and the hoisting device is arranged on the folding portal frame and is used for hoisting operation. The folding type portal frame hoisting device can be conveniently and rapidly contracted and transported when transition is needed, the problems that a conventional portal crane is fixed in a workplace and difficult to transition are solved, and the folding type portal frame hoisting device can be automatically unfolded for operation after being transported to the field and is high in environmental adaptability.
