The invention discloses a four-drum wheel type gantry crane portal frame which comprises brackets, a main beam, a transverse moving mechanism, reinforced frames I, reinforced frames II and connecting plates, wherein the two brackets are respectively arranged at the two ends of the main beam; the main beam is provided with the transverse moving mechanism by a track; the reinforced frames I which are connected and fixed with the main beam are respectively arranged at the two sides of the brackets; the reinforced frames II are respectively arranged at the outer sides of the reinforced frames I; the middle parts of the reinforced frames I are respectively connected with the middle parts of the reinforced frames II by the connecting plate. According to the four-drum wheel type gantry crane portal frame, the main beam is carried by the combined action of the brackets, the reinforced frames I and the reinforced frames II, so that the main beam is very stably carried, the bearing capacity of a crane is improved, and the service life of the crane is prolonged; the four-drum wheel type gantry crane portal frame is a novel crane portal frame which is simple in structure and novel in design.
