The invention discloses a rail-mounted gantry crane adopting a single semicircular main beam. The rail-mounted gantry crane comprises the semicircular main beam, a rigid door frame mechanism and a door frame lateral supporting mechanism, the semicircular main beam is horizontally arranged; the two rigid door frame mechanisms are arranged at the positions, close to the ends, of the semicircular main beams respectively. The door frame lateral supporting mechanism is arranged at the lower end of any rigid door frame mechanism and further connected with the end, on the same side as the rigid door frame mechanism, of the semicircular main beam. The requirements of low wind resistance, good rigidity, no rail gnawing and the like of the main structure of the rail-mounted gantry crane are met.
