EFA (mobile Bridge)
The EFA or Engin de Franchissement de l'Avant (forward crossing apparatus) is a field-deployable river crossing vehicle, used by combat engineers in the French Army. Unlike a bridge layer, which transports a bridge that is deployed off of the host vehicle, the EFA itself is a combined pontoon bridge and amphibious vehicle, enabling much more rapid redeployment of the mobile bridge structure and an additional use as a ferry (at the cost of being useless in returning to service damaged bridges). When needed, multiple EFA's can be combined in a series to create a traditional pontoon bridge. It has been built since 1989 by Chaudronnerie et Forges d'Alsace (CEFA), located in Soultz-sous-Forêts in the Bas-Rhin. Characteristics A single EFA, in ferry configuration, has a length of 34.55m on a loading surface of 96 m2 is ready in less than five minutes for the transportation of up to 70 tons of goods. In one hour it is able to make about 10-12 crossings over a of 100m length and eigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astern Propulsion
Astern propulsion (as applied to a ship) is a maneuver in which a ship's propelling mechanism is used to develop thrust in a retrograde direction. Astern propulsion does not necessarily imply the ship is moving astern (''in reverse''); astern propulsion is used to slow a ship by applying a force in the direction of the bow of the ship, instead of the stern. The equivalent concept for an airplane is thrust reversal. In a sailing ship astern propulsion can be achieved by the appropriate manipulation of the sails. In square-rigged ships 'backing the sails', that is, aligning the sails so that the wind impinged on the bow surface, could provide sufficient retrograde thrust to slow or reverse the ship. This maneuver had to be carried out with care as the rigging of masts and yards was principally designed to accept and transmit thrust in the forward direction. In a ship with a gas turbine A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Vehicles Of France
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruction, pro ...

Armoured Vehicle-launched Bridge
An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines, when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located, or sufficiently sturdy, a substantial concern when moving 60-ton tanks. The bridge layer unfolds and launches its cargo, providing a ready-made bridge across the obstacle in only minutes. Once the span has been put in place, the AVLB vehicle detaches from the bridge, and moves aside to allow traffic to pass. Once all of the vehicles have crossed ...

Bailey Bridge
A Bailey bridge is a type of portable, Prefabrication, pre-fabricated, Truss Bridge, truss bridge. It was developed in 1940–1941 by the British Empire in World War II, British for military use during the World War II, Second World War and saw extensive use by British, Canadian and American Military engineering, military engineering units. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without the use of a crane. These bridges were strong enough to carry tanks. Bailey bridges continue to be used extensively in civil engineering construction projects and to provide temporary crossings for pedestrian and vehicle traffic. Design The success of the Bailey bridge was due to the simplicity of the fabrication and assembly of its modular components, combined with the ability to erect and deploy sections with a minimum ...

Bas-Rhin
Bas-Rhin () is a department in Alsace which is a part of the Grand Est region of France. The name means 'Lower Rhine', referring to its lower altitude among the two French Rhine departments: it is downstream of the Haut-Rhin (Upper Rhine) department. Both belong to the European Upper Rhine region. It is, with the Haut-Rhin (Upper Rhine), one of the two departments of the traditional Alsace region which until 1871, also included the area now known as the Territoire de Belfort. The more populous and densely populated of the pair, it had 1,152,662 inhabitants in 2021. The prefecture is based in Strasbourg. The INSEE and Post Code is 67.

Pontoon Bridge
A pontoon bridge (or ponton bridge), also known as a floating bridge, is a bridge that uses float (nautical), floats or shallow-draft (hull), draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon bridges in civilian use that can carry highway traffic; generally, the relatively high potential for collapse and sinking (e.g. due to waves and collisions) and high continuous maintenance costs makes pontoons unattractive for most civilian construction. Permanent floating bridges are useful for sheltered water crossings if it is not considered economically feasible to suspend a bridge from anchored Pier (architecture), piers (such as in deep water). Such bridges can require a section that is elevated or can be raised or removed to allow waterborne traffic to pass. Notable permanent pontoo ...

Soultz-sous-Forêts
Soultz-sous-Forêts (; ) is a commune in the Bas-Rhin department in Grand Est in north-eastern France. The French revolution In December 1788 Mary de Bode who had been born in England and her German born husband Baron de Bode arrived in Soultz-sous-Forêts. The Baron was given the fiefdom of Soultz-sous-Forêts by the Archbishop of Cologne ( Maximilian Franz of Austria). Mary described Soultz-sous-Forêts as a land "flowing with corn and oil and wine." They hoped that the French Revolution would not affect them, but at the end of 1794 the Baron and Baroness de Bode moved out of the town, before they mistakenly returned. They were lucky to make a quick escape over the mountains, but they left all their riches and five of their children behind them. Clement, one of their sons, and his son tried unsuccessfully, for seventy years, to regain the rights and riches they lost in the 1790s. In June 1854, the case of the de Bode family was debated in the British Houses of Parliament ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
