The portal crane mounting and dismounting system comprises a portal crane, the portal crane comprises a hoisting main beam, a walking wheel seat and supporting legs, the supporting legs are connected and supported between the hoisting main beam and the walking wheel seat, the walking wheel seat is used for moving on a track, bottom beams are installed at the bottoms of the two ends of the hoisting main beam respectively, and the supporting legs are arranged on the two sides of the two ends of the hoisting main beam respectively. Traveling wheel seats are respectively arranged on two sides of two ends of the hoisting main beam, two ends of the supporting leg on each side are respectively hinged with the traveling wheel seat on the same side and the bottom beam, a gear is mounted on one side of each traveling wheel seat, racks are mounted on the tracks on two sides and correspond to the traveling wheel seats, and the gears are in meshed transmission with the racks; and the two jacking systems are used for being arranged below the two ends of the hoisting main beam correspondingly. By adopting the structure to mount the portal crane, the quick, efficient, economical and safe mounting or dismounting can be realized without the help of external large-scale hoisting equipment and only with the help of simple tools and structures.
