description | The invention discloses a hole passing method for a bridge machine, and relates to the technical field of bridge construction. The hole passing method for the bridge girder erection machine comprises the steps that the fixing shell is fixed to one side of the upper surface of a girder, the outer wall of the contact plate crosses over the boundary of the girder, the height of the contact plate is lower than the upper surface of the girder, the girder is lifted through a crown block, the bridge girder erection machine is moved towards the direction close to a standard span and stopped till the distance between the bridge girder erection machine and the standard span is 47.0 m, and the bridge girder erection machine is in a balanced state. According to the hole passing method of the bridge machine, in the process that a pier makes slow contact with a beam, a contact plate on the lower side of a fixing shell on the beam face makes slow contact with the upper surface of the previous beam, the contact plate is retr |
