A Weapon Of Mass Destruction For the Middle Ages: The Trabuco

Born out of the tumultuous battles of the Middle Ages, the Trabuco is a powerful weapon used to crush walls, or bypass them completely, flinging all manner of objects to the other side. The cousin of the catapult, but with a simpler mechanism, the counterweighted devices were used not just for destruction, but were actually one of the first instances of biological warfare. It has been reported that, during the Bubonic Plague, Trabuco were employed to hurl disease-riddled corpses into population areas in the hopes of spreading death and disease.

 

A Trabuco operates from the forces of kinetic energy, unleashed by a counterweight, attached to sling-type mechanics. Originally, the devices were designed to be small and moveable, with a throwing capacity of a few hundred pounds. Over time, however, they grew in strength, eventually capable of hurtling 3000 pounds of rock and debris hundreds of feet. The structure of a traditional Trabuco consists of a long arm mounted on a sturdy base, or wheeled cart. A hefty counterweight is used to pull back the arm, and once released, harnesses that energy to launch its contents across great distances. Read This Article for more information.

 

Those first, small Trabuco are thought to have originated in China sometime around 400 B.C., but it was their arrival in Europe, around 1000 A.D., spreading first to the Byzantine and Persian Empires and then into Scandinavia, that saw their widespread deployment. During the tumultuous and bloody period of siege-mentality engendered by the Crusades, the Trabuco rose to its greatest prominence.

 

The Trabuco would remain as a primary weapon of war for centuries. Only with the advent of gunpowder was the Trabuco finally supplanted by more rapid and powerful cannons, sometime in the 15th and 16th centuries. Hernando Cortez, in his conquest of Tenochtitlan in 1521, ordered the last known military deployment of a Trabuco when his men ran out of gunpowder.

 

Today the once-lethal weapons are used for less nefarious purposes, providing a great resource for teaching mechanics, or for contests of a fun, competitive nature.

National Steel Car: New Changes Under Gregory James Aziz

The rolling stock manufacturing industry in Canada is booming, thanks to the effort of Gregory James Aziz. He is the president, chairman, and chief executive officer of the National Steel Car, which he purchased from Dofasco in 1994. Gregory J Aziz stated that the reason why he bought the National Steel Car is that he wanted to see how he would be able to transform the company from the present condition he acquired it. When he bought the company in 1994, he found out that there are still 500 people working who were hired by the former owners. He decided to retain them and asked them to become the mentors of the new employees who will be hired by Gregory James Aziz. The new employees, numbering at 2,500, were later on trained by the older employees of the National Steel Car.

 

 

1Gregory James Aziz knew the secrets to success. As he hired additional people to work on manufacturing train cars, he also targeted a new objective. He advised his employees that they would have to increase their production, and from the normal 3,500 annual rolling stocks made, the newly refurbished National Steel Car managed to increase the number to 12,500 rolling stocks produced every year. Gregory James Aziz is proud of all the employees who are working hard to keep the National Steel Car as one of the most competitive companies in Canada. He even dedicated some of the awards given to him to those who are determined in working hard for the company. Find Related Information Here.

 

 

The National Steel Car is slowly becoming one of the most profitable companies in Canada, thanks to the continuous efforts of Gregory James Aziz to promote the vehicle overseas. Presently, the company’s clients are only American transport companies, but the visionary business genius wanted to change it. He wanted to partner with other countries around the world, so Gregory James Aziz is sending companies in other continents about his business.

 

 

The National Steel Car has experienced so many challenges during their 100-plus year history. Gregory James Aziz stated that it only made the company more resilient and immune to changes. For now, the next challenge that they would have to address is the growing demand for products manufactured by the National Steel Car. Gregory James Aziz must think how he could be able to address the growing number of people who wanted to get hold of their products and making the best out of it.
