The invention discloses a metallurgical bridge crane. The metallurgical bridge crane comprises a cross beam, movable pulley blocks, lifting forks, lifting hooks and a plurality of pin shafts used for hinging two parts. The two parts comprise the first part and the second part which is at least partially located inside the first part so as to be hinged to the first part through the pin shafts. The two ends of each pin shaft extend out of the first part. Grooves are formed in the positions, close to the two ends, of each pin shaft. Baffles used for preventing the pin shafts from being disengaged from the two parts are inserted in the grooves, and the baffles are fixed to the first part. Indicating rods are fixedly arranged at the ends of the pin shafts. By the adoption of the metallurgical bridge crane, the parts can be prevented from being disengaged, and safety accidents are avoided.
