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.
Underslung (lower-beam) movable scaffolding system used during construction of the Aurachtalbrücke Emskirchen [] (2015). 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 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 ...
The ABLE places a launch rail over the gap and then booms the bridge across, while the bridge is assembled it slowly launches meaning that the bridge requires no pre planning or surveying. the system that is used to launch the bridge can also retrieve the bridge as well. Two Bridging Vehicles (BV) carry the remainder of the bridge set.

A gantry crane has a hoist in a fixed machinery house or on a trolley that runs horizontally along rails, usually fitted on a single beam (mono-girder) or two beams (twin-girder). The crane frame is supported on a gantry system with equalized beams and wheels that run on the gantry rail, usually perpendicular to the trolley travel direction.
