The Trabuco has seen very long history. It was originally a weapon of war that was invented in China in 600 B.C. They are similar to the catapult with both used during sieges during the Middle Ages. However, unlike the catapult and its other cousins, the mangonels and ballistrae, the mechanism of The Trabuco was quite uncomplicated.
The simple mechanism of the Trabuco worked by transforming the potential energy into kinetic energy. The Trabuco was used to both smash walls and to fire projectiles. They were built with wheels so that they could be maneuvered around according to the battle strategy. Read more on sinonimos.com.br.
Girded with the Trabuco, those laying siege could launch projectiles 800 meters. It first came to Europe in A.D. 600. It came to England in 1216 on tudo-sobre.estadao.com.br. After beginning the construction of a Tribaco, it took about 12 days to complete it. All manner of projectiles were thrown from these: boulders, parts of ruins, diseased corpses, fire balls, etc. Throughout the history of its use, both very large and very small Trabucos were built and used. In 1304 Edward Longshanks ordered the construction of an especially enormous one which he named “Warwolf.” The average Trabuco was big enough to launch projectiles of 50 to 100 kilos.
The Trabuco stopped being used when gunpowder came into military use. The last record of the military using it was by Hernan Cortez’ siege of the Aztec capital, Tenochtitlan in 1521. And the only reason it was used in that instance is because gunpowder wasn’t available at the moment. However, the world certainly hasn’t seen the last of these guys. Versions of Trabucos are still in use today, but only as a source of fun. For example, there are pumpkin throwing championships that use Trabucos based on youtube.com. The Trabuco is also used by science teachers to demonstrate physical principles.
