As the most advanced bridge girder erection machine,SLJ900/32 transportation and erection integrated machine without nose girder is composed of girder,running system,hoisting system,transmission system,hydraulic system,electrical system,safety device and the like.The boundary dimension of the complete machine is 91.8×7.4×9m(L×W×H)with the rated hoisting capacity of 900t.This machine is used to transport and erect the prestressing reinforced concrete box girder with the size of 32m,24m and 20m for high speed railway and passenger transport line.This machine can go through the tunnels with speed limit of 250Km and 350Km by delivering the full span box girder.It can erect the girder at the tunnel entrance,in the tunnel as well as on the small curve of the 25% big ramp.Compared with the existing transportation and erection integrated machine,this machine is easy to be operated because the transportation and erection of girders can be completed only by the main engine without laying down the nose girder.It is also featured with timesaving erection of start-end span box girders,safety as well as convenient site transfer.The triangle frame structure is adopted for the main landing leg so there is no need to anchor it with the pier.The fixed torque motor as well as torque transducer is set on the top of the main landing leg to guarantee the stability and safety when the complete machine goes through the span.
