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 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 ...
A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles.

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 ...
A wooden lifting gantry on rails was connected to the V-1 lifting lug to hoist and move it onto the launching spot at the lower end of the launching ramp. [ 28 ] Fueling and Charging : [ verification needed ] Via the tank filler cap, 640 litres (140 imp gal) of petrol ( German : B-Stoff ) were added (later longer-range models held more).

A-35 and A-43 were developed for launching short range surface-to-air missiles, the A-50 for the long-range PAAMS air defense system, and the A-70 launcher for longer missiles such as the MdCN naval land attack cruise missile. The numbers refer to the approximate length of the missile which can be accommodated, in decimetres, i.e. the A-43 can ...
