Steel Girder Bridge Launching

steel girder bridge launching crane

steel girder bridge launching crane classification:

steel girder bridge launching crane that runs on roads and railway tracks and is used to erect small span beams. Because of its high efficiency, the design of railway bridges in China is considered as the design principle. Its fuselage is huge, beyond the limit of railway transportation, it must be dismantled and transported, and then assembled and used after arriving at the construction site.

steel girder bridge launching crane advantages:

       In order to adapt to the curved bridge, the boom of the machine can swing a small amount in the horizontal plane. The method of locating the beam is the same as that used for the double cantilever bridge erecting machine (shifting beam or dial). The advantage of this machine is that the balance weight is cancelled, the locomotive push is no longer needed, the feeding beam does not need the bridge head twisting line, the mechanization degree is improved, and the safety performance is improved. This is the case for a sling bridge that weighs 130 tons.
