Saint-Chamond (tank)
The Saint-Chamond () was the second French tank to enter service during the First World War, with 400 manufactured from April 1917 to July 1918. Although not a tank by a strict definition of a heavily armoured turreted vehicle, it is generally accepted and described as such in accounts of early tank development. It takes its name from the commune of Saint-Chamond where its manufacturers Compagnie des forges et aciéries de la marine et d'Homécourt (FAMH) were based. Born of the commercial rivalry existing with the makers of the Schneider CA1 tank, the Saint-Chamond was an underpowered and fundamentally inadequate design. Its principal weakness was its Holt caterpillar tracks. They were much too short in relation to the vehicle's length and weight (23 tons). Later models attempted to rectify some of the tank's original flaws by installing wider and stronger track shoes, thicker frontal armour and the more effective 75mm Mle 1897 field gun. Altogether 400 Saint-Chamond tanks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Tank
A heavy tank is a tank classification produced from World War I to the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes. Role Heavy tanks achieved their greatest, albeit limited, success when fighting lighter tanks and destroying fortifications. Heavy tanks often saw limited combat in their intended roles, instead becoming mobile pillboxes or defensive positions, such as the German Tiger I and Tiger II designs, or the Soviet Kliment Voroshilov tank, KV and IS tank family, IS designs. Design Heavy tanks feature very heavy vehicle armour, armor and weapons relative to lighter tanks. Many heavy tanks shared components with lighter tanks. For example, the US M103 (heavy tank), M103 heavy tank shared many components with the lighter Patton tank, including transmission and engine. As a result, they tend to be either underpowered and comparatively slow, or hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holt Company
The Holt Manufacturing Company began with the 1883 founding of Stockton Wheel Service in Stockton, California, United States. Benjamin Holt, later credited with patenting the first workable crawler ("caterpillar") tractor design, incorporated the Holt Manufacturing Company in 1892. Holt Manufacturing Company was the first company to successfully manufacture a continuous track tractor ( Hornsby in England manufactured at least two full length "track steer" machines, and their patent was later purchased by Holt in 1913, allowing Holt to claim to be the "inventor" of the crawler tractor.) By the early 20th century, Holt Manufacturing Company was the leading manufacturer of combine harvesters in the US, and the leading California-based manufacturer of steam traction engines. Holt Manufacturing Company operated from Stockton, California, until opening a satellite facility in Walla Walla, Washington, to serve the Pacific Northwest. In 1909 Holt Manufacturing Company expanded by pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Chamond-Mondragón
In Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but a selected few are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. In many Protestant denominations, and following from Pauline usage, ''saint'' refers broadly to any holy Christian, without special recognition or selection. While the English word ''saint'' (deriving from the Latin ) originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special ...

Rimailho Model 1904TR
The 155 mm Rimailho Howitzer Model 1904TR (or just the 155 CTR) was a medium howitzer used by France before and during World War I. Background The name Rimailho comes from the designer of the gun Captain Emile Rimailho a French artillery officer who was also involved in the design and testing of the famous Canon de 75 modèle 1897. The gun was designed in 1904 and the TR in the name means 'Tir Rapide' or Rapid Fire in English. Captain Rimailho's goal was to produce a medium artillery piece capable of a rate of fire equal to the modèle (Mle) 1897, which was no small feat for a gun of that size. In service a well-trained gun crew could achieve a rate of 15 rounds per minute, however the 1904TR was mechanically complex and its high rate of fire placed a great deal of stress on the gun. Theory of operation * After each round is fired the gun's breech is opened automatically . * While the gun runs back into battery the breech is held open. * The crew places a cartridge and sh ...

Railcar
A railcar (not to be confused with the generic term railroad car or railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (or carriage, car, unit), with a driver's cab at one or both ends. In its simplest form, a "railcar" may also be little more than a motorized railway handcar, draisine or railbus. Some railway companies, such as the Great Western, termed such vehicles " railmotors" (or "rail motors"). Self-powered railcars were once common in North America; and termed Doodlebugs. Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called " rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). Alternative use In Australia, the term is sometimes also used as an alternative name for the small types of multiple un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holt Tractor
The Holt tractors were a range of continuous track haulers built by the Holt Manufacturing Company of Stockton, California which were named after company founder Benjamin Holt. Between 1908 and 1913, twenty-seven of the first 100 Holt caterpillar track-type tractors were used on the Los Angeles Aqueduct project, which provided a good proving ground for these machines. Military use They were widely used by the British, French and American armies in the First World War for hauling heavy artillery including the BL 9.2-inch howitzer and the BL 8-inch howitzer. Around 2,000 Holt 75s along with 698 Holt 120s and 63 Holt 60s saw military use during the war. The French Schneider CA1 and Saint-Chamond and German A7V tanks were based on Holt tractors. Specification There were at least three models used for military purposes: the Holt 75, the Holt 120 and to a lesser extent the Holt 60. The Holt 75 was first produced in 1913. It used two tracks for steering. It had a maximum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levavasseur Project
The Levavasseur project was an early project for a tank designed in 1903 by the French Captain Léon René Levavasseur (1860-1942) of the 6th Artillery Battalion, described as a "self propelled cannon project" (French: ''Projet de canon autopropulseur''). It is considered as the first description, made by a soldier, of what would come to be known as the tank. Levavasseur was a graduate of Ecole Polytechnique, of the promotion of 1881. According to ''Armoured Fighting Vehicles of the World'': Submission The project was submitted to the French Technical Artillery Committee (''Comité Général d'Artillerie''), and after two years of study was presented to the Army Minister by the General President of the Committee. The general described the project in letter No.135, dated 1 February 1905: Design The locomotive mechanism is then described as a type of continuous track, supporting an armoured box with a weapon: Reception The Artillery Technical Committee raised three major obje ...

President Of The French Republic
The president of France, officially the president of the French Republic (), is the executive head of state of France, and the commander-in-chief of the French Armed Forces. As the presidency is the supreme magistracy of the country, the position is the highest office in France. The powers, functions and duties of prior presidential offices, in addition to their relation with the prime minister and government of France, have over time differed with the various constitutional documents since the Second Republic. The president of the French Republic is the co-prince of Andorra, grand master of the Legion of Honour and of the National Order of Merit. The officeholder is also honorary proto-canon of the Archbasilica of Saint John Lateran in Rome, although some have rejected the title in the past. The current president is Emmanuel Macron, who succeeded François Hollande on 14 May 2017 following the 2017 presidential election, and was inaugurated for a second term on 7 May ...

Baby Holt
Benjamin Leroy Holt (January 1, 1849 – December 5, 1920) was an American businessman and inventor who patented and manufactured the first practical crawler-type tread tractor. The continuous-type track is used for heavy agricultural and engineering vehicles to spread the weight over a large area to prevent the vehicle from sinking into soft ground. He founded with his brothers the Holt Manufacturing Company. Early life The youngest of four brothers and eleven siblings, the children of William Knox Holt and first, Eliza Jane Virgin, and later Harriet Parker Ames of Concord, New Hampshire. William Knox Holt owned a sawmill that made hardwood for wagon and coach construction. In 1864, Benjamin's brother Charles H. Holt arrived in San Francisco, California where he founded C. H. Holt and Co. The company produced wooden wheels for wagons and, later on, steel streetcar wheels. Brothers William Harrison Holt and Ames Frank Holt arrived in 1871. The company sold hardwood, lumber, wag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
