ABSTRACT:
A rapid deployment stationary bridge. The bridge comprises a central girder lanked by two side girders, each of the central and side girders consisting of a plurality of aligned and connected sections.
For deployment the central girder is first assembled on one bank of an obstacle by aligning and interconnecting the constituent sections thereof. As the assembly progresses the central girder is launched by gradual advancing it towards the opposite bank. Some time after the commencement of the assembly and launching of the central girder the side girders are assembled by slidably mounting the constituent sections of each side girder in alignment on one side of the central girder and interconnecting them. In the course of their being assembled, the side girders are launched in such a way that the advancement of the side girders lags behind the advancement of the central girder.
