In 1857, a passenger lift was installed in a department store located on Broadway, corner of Broome Street in New York City. Steam moved it up five floors in under a minute. Back then, that was fast. In contrast to that, today orange county elevator service in tallest buildings, such as the Sears Tower in Chicago, quickly rise 412 meters (1353 feet) in less than a minute.
Currently, the tallest building world, the Burj Khalifa Tower in Dubai, which is 828 m high has lifts from the Otis Elevator Company climbing the longest distance in the world: 504 meters; also has access lift on the world's highest: 638 meters; and lift the world's fastest double cabin: 10 meters per second.
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.
Parachute failure or imbalance of traction cables (a. Electro-dynamic). Their movement is instantaneous and progressive, and has high and medium speed. It consists of a lever system whose motion actuates wedges or rollers that are in a box along with the guides (box wedges). When the fall of the car is given or exceeds the rated speed, the guides are bitten by wedges or rollers, thus arresting the free fall.
As they were taller buildings, people felt less inclined to climb long steps. Department stores began to flourish, and the need arose for a device that moved customers from one floor to another with minimal effort. The forklift inspired an American Vermont, Elisha G. Otis, to invent an lift with a toothed system, allowing for cushioning its fall in case of an accident. It was the first demonstration of a safety system for passenger cranes.
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.
Currently, lifts operate controls with electronic microprocessors using artificial intelligence algorithms to determine how to manage the response to requests for coordinating the various teams to work together. It was also invented by Otis in 1979. The boxes detect system errors, which in case of failure is displayed by an error code so that the lift mechanic knows the reason for stopping.
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.
