摘要： A folding tactical bridge module and bridging system and method of deploy and retrieval. Each module is made up of three longitudinally collapsible units interconnected and folded in a side-by-side arrangement to be carried by a bridge transporter vehicle. Each unit includes an arched roadway portion made up of two arcuate segments with a hinge at the centerline and a truss hingedly connected at each longitudinal edge. Tensile links tie the edges of the arched roadway together. The module folds in two ways with the tie links nested between the vertically collapsed first folded roadway segments which in turn are nested between a pair of vertical trusses. The three units of each module are in turn folded a second time into a side-by-side compact relation upon a transporter deploying vehicle. The bridge may be expanded and emplaced by the bridge transporter vehicle and its two-man crew using self-contained extendable-retractable interconnectable traversing beams associated with each of its three units.

摘要： A modular lightweight bridge comprises a pair of tubular truss formed spans, each of which include a plurality of modules hinged to one another at locations on the bottom of the bridge for folding the bridge for transport prior to deployment of the bridge. Each span has a unique high strength fabric deck or roadway surface tensioned across the upper side of the truss chord members. The bridge is uniquely captively mounted on a trailer by rollers for transporting the bridge when it is in its folded mode. When the bridge is to be deployed, each span is unfolded by pivoting the modules with respect to one another about vertical axes so that the spans expand longitudinally with respect to the trailer. The spans are then pivoted 90.degree. downwardly about longitudinally extending horizontal axes and the bridge rolled rearwardly from the trailer over the gap to be spanned. Due to the unique captive roller interconnection between the bridge assembly and its transport-deployment trailer, the trailer can thereafter be stored beneath the deployed bridge hanging down into the gully or gap. When a decision is made to remove the bridge, the trailer can be towed from either side back over the bank of the gap and the bridge refolded for mounting on and transport by the trailer.
摘要翻译：模块化轻型桥梁包括一对管状桁架跨距，其中每一个包括多个模块，所述多个模块在桥的底部处的位置处彼此铰接，用于在桥梁展开之前折叠桥架用于运输。每个跨度都具有独特的高强度织物甲板或桁架弦杆构件的上侧张紧的道路表面。桥梁独特地通过滚轮独立地安装在拖车上，用于在桥梁处于折叠模式时运输桥梁。当要部署桥梁时，通过围绕垂直轴线相对于彼此枢转模块来展开每个跨距，使得跨度相对于拖车纵向地扩展。然后，跨越纵向延伸的水平轴线向下枢转90°，并且桥从拖车向后滚过间隙以跨越。由于桥接组件与其运输部署拖车之间的独特的互锁辊互连，此后可将拖车储存在部署的桥下，垂直向下延伸到沟槽或间隙中。当决定拆卸桥梁时，拖车可以从任何一侧拖到间隙的堤岸上，并且桥梁被重新折叠以安装在拖车上并由拖车运输。
