The invention discloses a crane bridge and a crane. The crane bridge comprises a main beam and supporting legs, the main beam is arranged on the supporting legs, a top beam is arranged above the main beam, the two ends of the top beam are connected with the supporting legs through connecting columns, lifting devices are arranged at the two ends of the main beam and the two ends of the top beam, and butt joint guide rails are arranged on the lifting devices. The top beam is arranged, so that the crane carriage performs the return stroke process on the top beam, and the return stroke function of the main beam is separated; according to the invention, the rails of the crane can be connected end to end, so that the crane carriages can operate circularly, a plurality of groups of crane carriages can run simultaneously, and the crane carriages do not influence one another, so that the ground manual assistance is reduced, the working efficiency of the crane is effectively improved, and the labor intensity of workers is reduced.

    本发明公开了起重机的桥架及起重机,包括主梁、支撑腿,所述主梁设置在支撑腿上,所述主梁上方设置有顶梁,所述顶梁两端通过连接柱连接支撑腿,所述主梁和顶梁的两端设置有升降装置,所述升降装置上设置有对接导轨。通过设置顶梁,使起重小车在顶梁上进行回程过程,分离主梁的回程功能;本发明既能使起重机的轨道首尾相接,使起重小车循环作业,又可同时运行多组起重小车,且起重小车之间不会相互影响,减少了地面人工辅助,有效提高了起重机的工作效率,降低工作人员的劳动强度。
