Image: Forth Bridge - Inchgarvie cantilever as seen from the landing stage

Description: Photograph of the Inchgarvie cantilever as seen from the landing stage. Explanatory descriptions of the work at this point are rendered almost impossible, by the fact that the views of Inchgarvie superstructure are mostly taken from the same and only locality. It will be observed that, as compared with some of the former views, the whole aspect of the structure has changed, a more pleasing effect being the result. A noticeable feature in this picture, is the excessive length of the 12 feet tube, connecting N and S piers, as compared with the corresponding ones on the Queensferry and Fife sides. This great length obviously necessitated additional support, which was duly provided by the lattice-work tie midway between the vertical columns. The platforms were put together as shown in former pictures, and the lifting operations conducted in a manner similar to that employed at the other two piers, with, however additional jacks and cross-girders in conjunction with vertical tie. The steel plates used in the lower portion of this cantilever are the heaviest throughout the structure. To support the diagonal struts during erection was a difficulty arising from the excessive longitudinal dimensions of this pier, their angle being in this case considerably increased, and was met by carrying up the verticals, and finishing the struts independently of same, later on, by means of steel ropes and cranes worked from the platforms above.
