The invention discloses a gantry crane production lifting system, which comprises a coded disc, which is arranged on a main transmission shaft of a transverse moving mechanism of a gantry crane; the U-shaped photoelectric sensor is mounted on the gantry crane, performs photoelectric correlation induction on the two sides of the opening and is used for outputting a pulse signal; the crane control device is electrically connected to the U-shaped photoelectric sensor and a transverse moving mechanism of the gantry crane; the code disc is provided with a plurality of size seams, the plurality of size seams are uniformly distributed around the center of the code disc, and photoelectric signals emitted by the U-shaped photoelectric sensor can pass through size peaks; the crane control device is configured to receive a detection signal fed back by the U-shaped photoelectric sensor and generate a transverse movement pulse parameter; and when the transverse movement pulse parameter is matched with the preset parking trigger threshold value, a driving motor of a transverse movement mechanism of the gantry crane is controlled through a preset multi-section type linear speed reduction signal. The method has the effects that the time consumed when the gantry crane is parked is shortened, and the productivity is improved.
