1906 - Plan Of The Rotating Bridge Over The North Sea Canal In Velsen (Holland)

Description: Civil Engineering BoardTechnical sheet taken from a work on civil engineering, from 1906: “Swing bridge on the North Sea Canal in Velsen (Holland)". Formerly mounted on miter. Fairly thin paper. engraving original from the period, it is not a reproduction.Numerous figures representing the constructive details of a swing bridge. You can see longitudinal sections, plans and locking mechanisms. This plate precisely illustrates the technical aspects of a swing bridge located in Velsen in Holland, designed to allow the passage of ships on the North Sea canal. Such a work represents an important advance in civil engineering at the beginning of the 20th century and demonstrates the evolution of transport infrastructure.The engraving shows eight distinct figures, each depicting a different aspect of the swing bridge. Figure 1 shows a longitudinal section along the axis of the track with details of the sleepers, ballast and expansion devices. Figures 1 and 2 reveal the bridge locks and the movable track of the South Key with precise annotations on the structural elements. Figure 2 is a plan seen from above showing the arrangement of the rails and transverse supports. Figure 3 offers a section through the axis of the pivot revealing the internal structure of the rotating mechanism and its foundations. The plan of the pivot is shown in Figure 4, highlighting the central assembly that allows the bridge to rotate. Figures 5 and 6 illustrate the lock and wedge operating levers, with particular attention to mechanical details. Finally, Figures 7 and 8 present the contact indicating the arrival of the bridge at its closed position, thus highlighting the precise indication system for controlling the movement of the bridge. Every technical detail is finely drawn, providing an in-depth understanding of the individual components as well as their joint operation within this work of civil engineering.Ideal for a loft, industrial, architectural type decoration, for anyone looking for originality and authenticity, or for any collector, engineer...
