The Trabuco is a catapult-like siege weapon used in war, particularly in pre-medieval times, to launch stones and other projectiles over the walls of cities. During these times, it was common for cities to be walled or to have a fort wall around the outer limits of the city. Each opening to the city was manned by guards and in larger, more important cities, cavalry was kept nearby, both within and outside of the walled city gates. This triple protection gave the city a highly protected interior.
A Trabuco, the war weapon of choice to use against these heavily fortified cities, was the only type of weapon which could reasonably be successful. By launching rocks, granite stones, and even metallic or primitive explosive devices with the leather sling of the Trabuco, enemy troops could launch effective attacks against the city, reaching far over the city walls and reaching building and citizens inside. Even by attacking a building, a Trabuco can create enough falling rocks and falling debris to wipe out quite a few people underneath. This was certainly an effective military machine on em.com.br.
The Trabuco was made very similarly to a catapult, though it was taller, had a leaner wooden support structure, and a longer leather sling in which to put the rocks and other projectiles. This gave the Trabuco a much farther throwing distance than a regular medieval catapult. The structure was built as a completely circular throwing sling, so that there would be no backlash on the support of the structure when the arm was done slinging. Instead, the arm was able to swing all the way around in a complete arc, thus reducing wear and tear on the Trabuco framework on banco.bradesco.
According to youtube.com, putting a city under siege required immense holding resources and, as long as the city itself did not have any underground tunnels through which to bring extra resources, using many a Trabuco could have almost guaranteed an attacking party success. This is, of course, providing that the city does not have a Trabuco or two of its own with which to retaliate at that distance. An enemy could, theoretically, continue to use stones from the vast resources outside of the city, whereas the city would only be able to catapult back what is being thrown at them, providing it does not break into pieces, or parts of damaged buildings. The Trabuco was, indeed, an effective siege war machine.
