    Heavy Girder Over Bridge The Heavy Girder Over Bridge (HGOB) provides a lower profile allowing easier crossing for heavy transporters and tankers on line of communication routes. The bridge is transported on 1 DROPS pallet of a 14 tonne truck. A Royal Engineers Section and a crane is used to construct the bridge.

    en.wikipedia.org/wiki/Launching_gantry

    Underslung (lower-beam) launching gantry used for Skyline guideway construction (2015). A launching gantry (also called bridge building crane, and bridge-building machine) is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects.

  5. Movable scaffolding system - Wikipedia

    en.wikipedia.org/wiki/Movable_scaffolding_system

    A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place. The movable scaffolding system is used to support a form while the concrete is cured; once the segment is complete, the scaffold and forms are moved to ...

  6. Girder bridge - Wikipedia

    en.wikipedia.org/wiki/Girder_bridge

    The stubs at the eastern end of the Dunn Memorial Bridge give a good cross section of girder bridge construction. A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape. These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in ...

    en.wikipedia.org/wiki/Pin_and_hanger_assembly

    Attempts have been made to increase the safety of bridges with pin and hanger assemblies by adding some form of redundancy to the assembly. Retrofits that add redundancy to pin and hanger assemblies include adding a "catcher's mitt"‍—‌a short steel beam attached to the bottom of the cantilevered girder that extends out beneath the suspended girder to "catch" the suspended girder should ...

    en.wikipedia.org/wiki/SLJ900/32

    The SLJ900/32 as aforementioned, is 91 metres (299 ft) long, 7 metres (23 ft) wide, 9 m (29 ft 6 in) tall and weighs around 580 tonnes (640 short tons). [4] Compared to conventional cranes which require clear land and are typically only able to lift a few meters of bridge material per-lift, the SLJ900/32 is capable of lifting an entire large segment of bridging material (some of which weigh ...

  9. Beam bridge - Wikipedia

    en.wikipedia.org/wiki/Beam_bridge

    Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
