The utility model discloses a compact vertical lifting device, and relates to the field of construction equipment of power transformation engineering of an electric power system. A compact vertical structure converter valve is core equipment of a convertor station at present; the technical requirements of equipment are low; and the compact vertical structure converter valve needs to be ensured by a series of strict quality control and correct and reasonable construction procedures and technologies in the period of installation. The compact vertical lifting device is arranged on a lower chord of a roof truss; a lifting track is arranged on the lower chord of the roof truss; a plurality of independent monorail cranes are arranged on the lifting track and can move on the lifting track; two monorail cranes on the two adjacent tracks in the lifting track are connected with a balance hanging beam; the distance from the balance hanging beam to the connected point of the monorail cranes at two ends is equal to that between the two adjacent tracks in the lifting track; and the balance hanging beam is connected with an equipment hanging bracket. According to the technical scheme, when the equipment is lifted, the using effect is good; especially in installation of valve towers in multi-end flexible direct-current transmission substation projects, the labor intensity can be greatly relieved; the construction efficiency is improved; the overall valve hall is simple in installation, normative and reasonable; and the cost is reduced.
