As early as 336 B.

C., elevators are already known to have been in use in Ancient Rome. During the Middle Ages, “basket” elevators were used to transport goods to several mountains. During this time also, some secluded monasteries has no land access, that’s why elevators are already of great use.The etymology of the word “elevator” is derived from the modern Latin word ‘elevare,’ which means ‘raise’.

Elisha Graves Otis introduced the first safety contrivance of elevators in the year 1852. Then, Wener Von Siemens, a German inventor, invented the first electric elevator in the year 1880. Eventually, an easier way of using elevators was invented. It comes with automatic doors and it was patented in 1887. The first commercially installed electric elevator was during the year 1889.The early elevators are said to be open cars, compared to that of today which are enclosed ones. The early elevators are operated either manually (by people or animals) or by water-driven mechanisms. The source of power of some of these elevators is through water, as hydraulic elevators were also invented.

Hydraulic elevators require water pressure.Aside from hydraulic elevators and electric elevators, vacuum or also known as pneumatic elevators were also invented. Unlike hydraulic elevators which requires water as its source of power and electric elevators which are of great use today, vacuum or pneumatic elevators doesn’t require a machine to function.

As it is called vacuum, suction is used to transport the elevator in between floors.There are different types of elevators and each has a unique way of operating mechanism. It also varies in size, depending on where an elevator is to be constructed.The counterweight capabilities as elevators work in easy hoists. The elevator is balanced via a big counterweight that weighs the equal quantity because the elevator is half of loaded. Or in different words, 40-50 percent of the entire weight and the elevator.

And the counterweight functions whilst the elevator goes up the counterweight is going down, vice versa. Which enables the motor to effortlessly enhance or decrease the auto. due to the counterweight, the motor now’s the use of less pressure to either flow the automobile up or down. The elevator is greater secure, due to lesser pressure changed into used and much less strains on the cables. The counterweight additionally reduces the elevator amount of braking. a fully loaded elevator could be simply difficult to tug upwards if there have been no counterweights. The counterweight makes the manage of elevator vehicle easier.

 The safety brake is stopping the elevator car from crashing to the floor ground. there has been a spring loaded with hooks at the top of each automobile. It sprung in the direction of the metal tooth within the rail, locking and making the automobile accurately in function. the velocity governors is a regulating system with a heavy flywheel with big mechanical fingers inside it. The arms are within the flywheel with the aid of a spring.

some governors are mechanical and others are electromagnetics, others still use collectively mechanical and electric powered components.modern elevators safety gadget have more than one protection systems. Like a suspension bridge cable, cables in an elevator is made of numerous metal strands of wire twisted collectively so if a failure takes place, it will now not motive any troubles.

modern-day elevators now have a separate cables helping every automobile, so when one cable fails others are still functioning properly. despite the fact that all of the cables ruin, this device will still aid or keep the elevator in location. cutting-edge elevators now have a hydraulic gasoline spring to cushion the effect if the safety breaks will fail to make you a great deal safer inside the elevator.

Along with the many advancements today, technology can impart a big role in the development of even better elevators in the future. Nanotechnology is one of the several factors that can be taken into consideration to improve the use of elevators in the future. By nanotechnology, the elevators no longer need a technician because it can already repair itself of any damage or dirt. Nanotechnology can help in aiding the problems of elevators immediately.Another factor that can be considered is that elevators can travel at a faster speed.

Thus, it can travel at a faster speed especially to taller buildings but at a shorter span of time.Also, with the use of clean energy, future developments in elevators can already be renewable. It can no longer affect the environment and can be obtained at a very low cost. It can also help in improving the living conditions in some
