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 launching gantry is used to lift ...
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 Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
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 ...
Three precast segmental exit/entry ramps constructed both by the use of an overhead launching gantry and, for some spans, a heavy duty falsework support system. The dual three lane approaches on either side of the main bridge are 27.8 m (91 ft) wide, the width of the main bridge deck is 28.8 m (94 ft) and the ramp structures are 9.87 m (32.4 ft ...
Launch Post-launch : The steam piston, having separated from the V-1 at the end of the ramp during launch, was collected for re-use (the site nominally had only two pistons). Personnel in rubber boots and protective clothing used a catwalk along the ramp and washed the launching rail with brooms.
The goal of the Starship launch system is to be a fully reusable orbital launch and reentry vehicle. [170] The Starship launch system consists of two stages: a Super Heavy booster and a Starship spacecraft; [171] both have a body made from SAE 304L stainless steel [172] and are designed to hold liquid oxygen and liquid methane. Super Heavy and ...
