The invention discloses a lifting device for gearbox maintenance, which comprises a lifting ring, the lifting ring is tied with a plurality of steel wire ropes, the lower ends of the steel wire ropes are connected with a lifting hook assembly, the lifting hook assembly comprises a lifting lug, a cylindrical lifting rod and a lifting hook body, the upper end of the lifting rod is connected with the lifting lug, and the lower end of the lifting rod is connected with a circular base; a plurality of pairs of strip-shaped protrusions which are outward in the radial direction are evenly distributed on the suspender in the circumferential direction, the multiple lifting hook bodies correspond to the multiple pairs of strip-shaped protrusions in a one-to-one mode, and one ends of the lifting hook bodies are rotationally connected with the lower ends of the strip-shaped protrusions through pin shafts. The upper end of the hanging rod is sleeved with a limiting ring, the outer circle of the hanging rod is connected with a limiting pin, and the limiting pin is located in a groove between the strip-shaped protrusions. The lifting hook assembly further comprises a folding mechanism. The problem that the front end plate of the gearbox is prone to unhooking in the horizontal lifting process is effectively solved, production safety is guaranteed, and working efficiency is improved.
