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.
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 ...
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.
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 ...

A concrete curved-chord through girder bridge, sometimes known as a camelback bridge, [2] [i] is a type of concrete bridge most common in the U.S. state of Michigan and the Canadian province of Ontario. [1] C.V. Dewart, the first professional bridge engineer of the Michigan State Highway Department, designed the type. [3]
The medium girder bridge (MGB) is a lightweight, man-portable bridge that can be assembled without help from heavy equipment. In addition, it is also a deck type, two-girder bridging system capable of carrying loads up to and including main battle tanks (MBT).
A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel, a Belgian engineer who proposed this new bridge girder-type without diagonals in 1896. [ 1 ] Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints .
