Elevator from the past to the present
Since the beginning of history, mankind has been looking for a way to more efficiently transport cargo and passengers vertically to different levels. These devices for carrying goods up and down are known as the first elevators, and its history begins several hundred years before Christ, and the first elevators were called elevators and were moved by human and animal power or sometimes water mechanisms.
Modern elevators were built during the 1800s, and in these early elevators, the power was slowly converted from steam to hydraulic power. The first hydraulic elevators were designed using water pressure as a power source. These elevators were used to transport materials in factories, warehouses, and mines, and often in European factories.
In 1852, Elisha Graves Otis introduced the first safety device for elevators. Otis founded a company to manufacture elevators and went on to dominate the elevator industry. Today, the Otis elevator factory is the largest manufacturer of vertical transportation systems in the world.
The revolution in elevator technology began with the invention of hydraulics and electricity. Motor technology and control methods evolved rapidly, and electricity quickly became the accepted source of power, increasing the safety and speed of elevators significantly. The first electric elevator was built by German inventor Wener Von Siemens in 1880, and in 1889, the first commercially successful electric elevator was installed.
In 1887, an electric elevator with automatic doors that could close the elevator shaft was patented, and this invention made elevators safer.
Today, modern commercial buildings usually have multiple elevators with integrated control systems. In addition, most modern elevators have special group controls.
Today, the latest technology being discussed is related to space elevators, which use the same concept as the classic elevator. These samples will be used to transport people to the space station, and this concept could theoretically significantly reduce the costs of putting a person in space.
