In the previous issue, we talked about the key points of the bridge erecting machine design. In this issue, we will continue with this topic and take a look at how the construction hoist book is modified. When installing the steel main girder, the installation height of the steel main girder needs to be checked, and the height of the crossbeam can meet the requirements. If it cannot be satisfied, the support pad of the construction hoist needs to be increased. The transformation of the bridge erecting machine shall be carried out under the guidance of the manufacturer, and shall not exceed the allowable range of the bridge erecting machine itself to ensure the safety and stability of the bridge erecting machine structure.

The transformation of the construction hoist shall be carried out under the guidance of the manufacturer, and shall not exceed the allowable range of the bridge erecting machine itself to ensure the safety and stability of the bridge erecting machine structure. During steel beam assembly and transportation steel beam installation, the side main beam can be assembled in two sections on the beam storage area assembly pedestal according to the position of the support. Install it. During the assembly and transportation of the two sections of the main bridge's steel beams, attention should be paid to measures to protect the steel beams, such as supporting square wood, rubber skin, etc., to prevent hard contact between the steel beam and the pedestal or frame. The counterweight of the approach box girder can be used behind the first rush-span bridge erecting machine to realize the bridge erecting machine rushes across the hole. After passing the hole, the front fulcrum of the bridge erecting machine is placed on the auxiliary pier top cross track of the intermediate support. The position of the middle outrigger considers the span distance and the erection position of the steel beam in the later stage, and the middle outrigger is placed on the installed approach bridge. After rushing the span, the installation of the inner steel main beam, cross beam and small longitudinal beam of the first span can be completed. The reconstruction of the bridge erecting machine must start from the bridge itself and design a reasonable reconstruction plan. It is really a big project.
