| Abstract: | The pavilion-carrying gateway top girder of Beijing West Passenger's Railway Station is 51m in height and 1800t in weight. This paper describes the technique used for fabrication and erection (including assembling, sliding, measuring, welding, hoisting, positioning etc. ) of the pavilion as well as prctcnsioning of the 45m-span truss girder. Hoisting was carried out by a new technique of synchronic raise with hydralic jacks. Success of the erection is a result of an initiative efforts. |
