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.

    本发明公开了一种采用单根半圆形主梁的轨道吊,包括半圆形主梁、刚性门框机构以及门框侧向支撑机构;所述半圆形主梁水平向设置;所述刚性门框机构具有2个,分别设于所述半圆形主梁上靠近端部的位置;所述门框侧向支撑机构具有1个,设于任一所述刚性门框机构的下端上并还与该所述刚性门框机构同侧的所述半圆形主梁的端部相连。本发明满足轨道吊主结构的低风阻、刚性好和不啃轨等要求。
