An elevator or lift is a vertical transport system designed to move people or goods between different levels. It can be used to ascend or descend in a building or in an underground construction. It consists of mechanical, electrical and electronic parts that work together to achieve a safe means of mobility. The initial reference to an orange county elevator service appears in the works of the Roman architect Vitruvius, who says of Archimedes (ca. 287 BC - Ca. 212 BC).
This electroleva is retractable, ie traveling with cabin retracted not to press the strips of each floor through which passes (which would allow the opening of each of the doors and stopping the elevator). The reverse process occurs when the lift is required on another floor: the electroleva retracts before departure and only expands when it reaches the floor.
In the seventeenth century, there were prototypes in some buildings. Ancient and medieval lifts used drive systems based on crane mechanisms. The invention of another system based on the screw drive was perhaps the most important technology, which ultimately led to the creation of modern passenger variants.
The counterweight is also led by guides. Its function is exactly load balancing to facilitate the work of the engine and not force too much to handle the same load. Tractors crane groups are usually formed by a motor coupled to a speed reducer, whose output shaft is mounted sheave trailing cables by adhesion. In the lower or upper ends of car frame is a safety system, whether instantaneous or gradual.
Cruise control mechanism comprises two pulleys, one installed in an engine room and another vertically aligned with the first in the bottom of a hole. Both passes a steel cable whose ends are connected, one to a fixed point on a frame of cabs, and also to a lever system whose end is at the top of a frame. The cable is attached to a car at all times and is completely independent of traction cables, that is, not involved in securing the car and counterweight.
Oddly enough, Elisha Otis's talent as a designer was discovered while working as a master mechanic in a factory making bed frames Albany (New York State). He invented many labor-saving devices, and so was sent to New York, where he could better use his ability. There he designed and built the first lift with automatic safety mechanism in case there was any fault in a cable.
By 1853 he had established his own business to manufacture elevators, the elevator company Otis Elevator Company, which still exists today and is the first elevator company in the world has since installed 2.5 million elevators and escalators throughout the planet. The following year, Otis made the demonstration of this invention in an exhibition that took place in New York.
This emergency system can also be called "Rescue-matic". In ancient elevators, pressing the STOP button produced an instantaneous stopping of cabin, the traveler may be trapped between floors with no possibility of exit. In current models, this button has ceased to exist on the boards cabin, leaving only the alarm button and emergency device. For use by passengers in an emergency. Sometimes it is connected to a phone line from which you can request assistance in the event of being trapped.
