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.
The cabin is the basic element of an elevator system. It consists of two parts: the frame or chassis and the box or cabinet, or by a self-supporting cab. The frame is supported by vertical guides. Most lifts use a counterweight mechanism, which has a mass equal to that of its cabin, plus half of maximum permissible load, so that the engine does not have to move the entire mass of the car, but only a fraction. As a result, an empty lift is lighter than the counterweight.
The first model was built by Ivan Kulibin and installed in Winter Palace in 1793, while several years later another Kulibin variant was installed in Arkhangelsk, near Moscow. In 1823, a cabin upgrade was inaugurated in London. In 1851, a man named Waterman invented the first prototype forklift. It was a simple platform attached to a cable to raise and lower goods and people.
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.
The control system operates lift by electronic means in charge of running the direction of movement and selecting the floors in which it must stop. In 1925, the Otis Elevator Company Elevator Company invented the first control system with memory for groups of lifts, allowing automation and bypassing the default system.
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.
