    Designed for military uses, the prefabricated and standardized truss elements may be easily combined in various configurations to adapt to the needs at the site. In the image at right, note the use of doubled prefabrications to adapt to the span and load requirements. In other applications the trusses may be stacked vertically.


    Features


    i. Longitudinal trusses composed by modular steel panels pinned end to end
    ii. Transversal girders spanning between the longitudinal trusses
    iii. Steel lane decked roadway (single lane) on top of the transversal girders
    a. Rapidly modular design: components shall be fully interchangeable with all other of the same type
    b. Single lane roadway (clear width 4.2-4.5 m)
    c. Suitable for critical harsh environmental conditions:i. Temperatures: -20°C to +60°C.
    ii. Wind Speeds: average 45 m/s, gusting to 60 m/s
    d. Design Loads:
    i. Load Class: 40 tons of tandem wheeled load –(HS25-44 Highway Loading)
    ii. Effects of dynamic impact and vehicular eccentricity, wind, etc. (in accordance with Section 3 of the AASHTO or equivalent international standard)
    iii. Single lane bridges: be able to sustain a minimum 100,000 cycles of stress due to AASHTO HS25-44 truck (or equivalent international standard)or lane loading, including the effects of dynamic impact and vehicular eccentricity
    e. Rapidly erectable installation:
    i. Components shall be lifted and carried/lifted/installed by manpower alone, using appropriate tools where necessary
    ii. All connections to be made on site, utilizing pins/bolts easily installed with simple hand tools, (e.g. not use of special tools or on-site welding)
    iii. Modular span construction based on interconnected individual single span(s) with increment of 3 meters
    iv. Roadway with modular steel deck and pedestrian modular steel deck (optional) as cantilever fixed outside the bridge
    v. Cantilever installation method, launching the bridge across the gap without any temporary intermediate supports
