Plant to manufacture elongated elements of prestressed reinforced concrete

摘要: The invention concerns a plant to manufacture elongated concrete elements, particularly railway sleepers of prestressed reinforced concrete. In the according invention, forms for production said elements are supported on carriages (14.1 14.6) sliding along parallel side-by-side tracks (P1 P6), and operating machines (28a, 28b, 38, 45, 30, 46) designed perform in succession series operations positioned into limited working area, housed inside shed, mounted above substantially fixed respect longitudinal axis but movable transversely thereto. curing area is arranged externally area. case tensioning means reinforcement strands directly each slidable supporting forms.
