Elevator is one of the most important inventions in human history in vertical transportation. Most ancient types of Elevators were driven by man or animal power and were mostly used for the construction of the Pyramid in ancient Egypt.
It is strongly believed that the first drum-type lift was invented in 236 B.C. by Archimedes an ancient Greek mathematician, Engineer, and scientist.
In 1743, the first human-powered counter-weighted personal elevator called the flying chair was designed for King Louis the King of France. This flying chair was built to allow him access to her wife’s quarters on the third floor of the palace.
By the mid 19th century elevators powered by steam or water were available instead of man or animal power.
In 1852, Elisha Otis of New York invented an Elevator safety device (safety brake) which became a revolution in the vertical transportation industry. This safety device was designed to prevent free fall of the elevator platform if the hoisting ropes broke.
With the advent of electricity in the late nineteenth century, electric power was accessible to drive elevator cars. In 1880, Werner von Siemens a German electrical Engineer invented the first electric elevator.
In 1887, Alexander Miles an American inventor designed an elevator that would open and close its doors automatically when arriving or departing from a given floor.
By the early 1900s, with the advancement of motor technology, gearless traction elevators were introduced.
During the last 100 years, the elevator industry evolved and expanded, including more advanced safety and efficiency features. Vertical transportation was made more safer and convenient than ever before.
In 1983, VVVF control Elevators were developed for high accuracy in landing, smoothness in running, and Energy saving.
A compact type Permanent Magnet Gearless synchronous traction machine that is equipped with a permanent Magnet synchronous motor was introduced for elevators which has a high-efficiency factor, low starting current, large starting torque, smooth running comfort, safer, low noise, and compact size.
During that time different types of Elevators were introduced according to different requirements, such as double deck elevators, zigzag elevators, inclined elevators, twin elevators in one shaft, Machine room less Elevators, vertical/horizontal mix elevators, etc.
Also, for different types of buildings, different types of elevators were introduced to meet the building requirements. Such as Hospital Bed Elevators for Hospitals, Dumbwaiters for Restaurants and kitchens, Home Elevators for houses, Freight Elevators for factories, whare houses, manufacturing plants, etc. Observation Elevators for shopping malls, airports, etc.
In fact, today’s Elevators are the safest way in vertical transportation to travel to your destination and transport different types of cargo, equipment, luggage, food trolleys, vehicles, Hospital beds, and stretchers in the buildings vertically.
