That would be you without an elevator having to climb a 12 floor of a building, when you have time and are late or too many obstacles or reduced mobility of many people. Today, not conceive of life without these devices. In this article, we have the evolution of the elevator. Its past, present and future.
The first reference to the elevator is in the work of the Roman architect Vitruvius, who, in his writings, refers to Archimedes (s. III AC) as the first inventor of the elevator. These elevators had a very primitive system and consisted of booths that were held with rope and were pulled by animals or men to put them into operation. It is believed that these devices would be found installed in Egypt.
Later, in 1000, Ibn Khalaf al-Muradi, in the Book of Secrets, describes the use of a device like lifting system, but in order to raise weight on it and destroy buildings. Already in the seventeenth century in England and France they are the first prototypes lift.
While the aforementioned elevators used based on the mechanisms of a crane systems, systems begin to patent screw drive, which starts changing technology and the future of the elevators. The first model built to transport people Kulibin Ivan patented and installed in the Winter Palace in Moscow in 1793. Later, several lifts are installed in Moscow and in 1823 was opened one in London.
We will have to wait for 1851, when Waterman patented the first forklift. The mechanism was simple: a platform with a cable to carry objects and people. Thanks to this fact were built taller buildings and began to be used on large surfaces later.
The fact that marks the evolution of the elevator is the brainchild of American Elisha G., who designed the first elevator with a jagged system that served to cushion the fall in event of failure of the cable that held it. This improvement in security has increased the success of the invention.
This increased the use of elevators, because increased the confidence of the people. Later, Elisha G. established a company manufacturing elevators and patented one that worked with steam in 1861. The US company exists today and is the largest company of elevators and escalators in the world.
In 1846, another inventor, William Armstrong, change the elevator powered by steam hydraulic machines, which began operating in 1870. The elevator worked by a heavy piston moving in a cylinder by water pressure or oil producing the bombs.
Electric elevators, as known today, began to be used in the nineteenth century thanks to the invention of the German von Siemens in 1880. This inventor added the electric motor in the elevators. In turn, the cabin having up below the engine through gears rotating pinions. In 1887, another elevator with electric motor was invented, but this time worked by a coiled drum in the hoisting rope. elevators with gear bolts connecting the engine with drum used in the following years.
The elevators are increasingly modernized. In 1949, the figure of the elevator and automatic control switches installed. In addition, more security measures are installed in the doors. In 1957, the doors ceased to be manual and became automatic, as you can see today.
All these innovations were able to create the lift that used today and is found in most high-rise buildings around the world. Currently, they include the elevator that goes up the longest distance in the world with 504 meters, the climbing the world's highest at 638 meters; and the fastest in the world, climbing the floors at a speed of 10 meters per second.
Spain is the European country with more lifts. There are over a million lifts currently running. This fact makes 20,000 jobs are created and business figures of more than 2,200 million euros are reached. The structure of the buildings and houses made to become fundamental for life and are ahead of the United States, Italy and France concerning elevators.
The lift, as known today, consists of a cabin, which is subject to an armature that moves vertically by a motor.
It is the visible part of the lift and the most aesthetic, because it is that you will be able to see. It consists usually of floor, ceiling and panels. On multiple occasions, the elevators are used to set advertising both inside and outside. Therefore, this part can be decorated in many ways: stainless steel, mirror inside, advertising, plate colors, etc.
The cabins have various important accessories, such as ventilation, emergency light, the buttons on the floors, the emergency phone, railings and even to include video screens. Generally, most modern lifts are created for enjoyment and are spacious and nicely decorated sites.
As told above, the main feature of the interior is include a set of buttons to turn to a plant and control the opening and closing of doors and distress calls. The cabin is supported by a metal frame that becomes its casing. This frame includes suspension elements and a parachute in case of speeding, which will slow.
2. Machine room.
This space has the drive unit and control panel. This space has fallen precipitously due to advances in technology. This device aims to perform maintenance and emergency maneuvers.
Installation is simple and is placed at the top or bottom part of the elevator.
3. Control box.
This is the brain of the elevator. The drivers allow operation of the device, its monitoring and maintenance. This box allows calls attention and manage the rise and fall, effectively, up to 4 elevator cars.
The future of the elevators is written with magnetic levitation that allows them to move in a vertical and horizontal. These elevators have no cables or structure, they will move in a direction at an angle and to be able to go outside without fear. Thus, a building can be built in any manner and without creativity be restricted by the gap to be left to the elevator. This concept will be much more comfortable and versatile.
The first tests of this lift, which will construct buildings with several towers or houses in unconventional directions, will be conducted in 2017. This may give rise to create cities more typical of science fiction future.
It also aims to create more sustainable buildings through this system, though, at first, the prototype will have a high cost of installation.
What technologies can positively affect the elevator?
1. Biometric Access. This access allows, with only approach the entrance, the device identifies the person by facial, eye or fingerprint recognition and the doors would open. Upon entering, the elevator recognize his voice and follow his orders.
2. Natural user interface. lets you interact with the elevator by gestures and voice or thought can tell what floor you want to go, how fast or call the technician in case of failure.
3. Clean Energy. The elevators in the future are renewable. It is intended to have no impact on the atmosphere with a very low cost and to help improve the living conditions of developing countries.
4. Clean Energy Transportation. It could travel at very fast speeds, so that they could build much taller buildings and could travel in a very short time.
5. Connecting in the cloud. In the future, everything will be connected in the cloud. Therefore, you can access content to learn what you want in the process.
6. Nanotechnology. The lift can repair itself without a technician and any damage or dirt disappear immediately
7. mutant decoration. The cabin can be adapted to the environment you want to create; seats appear, unless you want to stand; It will sound the music you want; and even the light you will want and images and videos you like best be shown.
The elevator has changed the way of life of people. Its rapid evolution has made it a mystery how it will evolve in the future, but currently there are many clues to their future, which will be long and impressive. From AstarLifts, we committed to change and settled in Barcelona the best lifts in the sector.
