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).
He had built a first elevator probably in 236 BC, elevators were mentioned as cabs held with hemp rope and powered by hand or by animals. It is supposed that elevators of this type were installed in Sinai monastery in Egypt. In 1000, the Book of Secrets by Ibn Khalaf al-Muradi, Islamic Spain described the use of an winch and lifting device to raise a heavy weight to hit and destroy a fort.
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.
This system releases wedges against the guides to stop the car in case you get off at the wrong speed limit, preventing the car from falling freely even in the event that all cables are holding the cab are severed. In elevators today and according to regulations in each country or region also slows uphill, ie when the car goes. Sometimes a braking system is also installed in the 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.
Keep in mind that an lift has multiple safety devices to prevent any accidents and if any device fails, the elevator is automatically stopped. Any old lift has contacts on exterior doors, car doors, which break contact of cables. System security is a key element and to maximize this aspect several specific devices are used. An electromechanical door interlock helps access to the floors, making it impossible to open all doors except the floor in the cabin.
