The beginning of a suspended platform inside of a vertical cabin for the transport of people or materials heavy he was described for the first time for Roman architect Vitruvius, in century I B.C.
The rise was gotten using a counterbalance, that went up and went down under the control of a sheave moved for a winch of the side of is of the platform.
It is probable that these elevators have been used in the houses Romans with some floors, where would have been operated for slaves.
The first known elevator was what the king Luis XV ordered to install, in 1743, in the Palace of Versailles.
It bound its aposentos to the one of loving its, madame of Châteauroux, in the floor of low.
The name of the English is not known who, about 1800, thought about using an engine the vapor to move the elevators.
This motor one was installed in the ceiling and controlled rolling and to uncurl around of the handle of a cylinder.
In 1851, the American Elisha Serious Otis (1811-61) invented a security system that he hindered that the handle balanced, arresting it in a track and blocking it with a series of claws.
This also allowed the use of the equipment for people. To show the efficiency of its invention, in 1854, it ordered to cut the handle of an elevator that he himself piloted. The first elevator of passengers was inaugurated by it in 23 of March of 1857 in a store of five floors in New York.
In 1867, the Frenchman Léon François Edoux invented the elevator of hydraulical column.
The same Edoux constructed, in 1889, an elevator of 160 meters of height for the Eiffel Tower.
These elevators were 20 faster times of what its predecessors, who worked with traction.
In 1880, the German company Siemens & Halske used electric energy in the traction of the elevators.
It went up 22 meters in 11 seconds.
The electricity use allowed the introduction of interruptors to control the elevator in 1894.
