Zusammenfassung: | The invention discloses a method for correcting the flatness of an upper opening flange of a container crane stand column. The method comprises the following steps: (1) moving a container crane to a hoisting position; 2) perfecting a working platform of a stand column upper opening; (3) retesting a flange gap, and assembling and welding a jack support; (4) installing studs, and hoisting front and rear girders; and (5) conducting fire correction on the stand column upper opening flange, retesting the flange gap, and continuing fire correction if the flange gap is not qualified till the gap meets the requirement. The defects of an existing operation mode are overcome, and the high-altitude overall correction mode for flatness out-of-tolerance of the upper opening flange of the container crane stand column is met.
