900ttransportation and erection integrated machine adopts a three-pronged designingmode with elevation, transportation and erection. It is used to transport anderect prestressed reinforced box girders of 32m, 24m, and 20m (if necessary, itcan also erect non-standard box girders between 20 and 32m) in the high-speedrailway and passenger line. It can pass the hole with the whole set of boxgirders through the tunnel of 250km/h our 350km/h. It can erect girders attunnel portal or even inside the tunnel, the method of which is the same withtasks without tunnels. It can move and erect on the normal pavement, roadbed orfinished box girders without damning anything. It can erect girder on either sideof the girder yard without the problem of transferring sites. Compared withpresent launching girder, it can erect the beam smoothly without the auxiliarymachine, which is of less weight, simple form, needless to be anchored, easyoperation and high efficiency; easy operation in the entire machine’s spantransformation, and has a stronger adaptability for the operating conditions.

Accordingto different mechanical structures, there are 900t Single-beam TransportationAnd Erection Integrated Machine and 900t Double-beam Transportation AndErection Integrated Machine.
