The invention provides a door frame for a container crane and a manufacturing method. The door frame for the container crane comprises two door frame assemblies arranged oppositely and two connecting beams arranged between the two door frame assemblies. Each door frame assembly comprises two stand columns, the two ends of each stand column are provided with a first connecting port and a second connecting port respectively, and the two ends of the connecting beam are connected with the two stand columns respectively. The two ends of the upper cross beam are connected to the first connecting ports of the two stand columns respectively; the two ends of the lower cross beam are connected to the second connecting ports of the two stand columns respectively; the stand columns, the lower cross beams and the connecting beams are spiral steel pipes. The door frame for the container crane is formed by connecting the vertical columns, the lower cross beams and the connecting beams in the form of the spiral steel pipes, and has the advantages of being simple in structure, small in wheel pressure and high in wind resistance.
