Transverse rail transition linkage device

The utility model relates to a cross rail transition linkage device, which comprises a guide rail, which is used for being fixed on a bridge girder erection machine and extends along the direction parallel to a main beam of the bridge girder erection machine, a moving mechanism is arranged on the guide rail, and the moving mechanism can move along the guide rail; one end of the suspension mechanism is installed on the moving mechanism, the other end of the suspension mechanism is used for being fixed to a transverse rail, and when the bridge erecting machine is transferred, the transverse rail can move along with the bridge erecting machine. The guide rails are fixed on the supporting legs of the bridge girder erection machine, so that the cross rails can simultaneously cross along with the supporting legs, and the cross rails are connected with the moving mechanisms on the guide rails through the suspension mechanisms, so that the cross rails can conveniently move along the guide rails, and the cross-span gi
