Inside almost every four or more storey building, regardless if it is an office, school, house, or commercial structure, you will notice at least one elevator. This technology is one of the longest running machines that still function as what it was designed for: to provide people and things a lift.
More than Lifting
Elevators can also add as much as 10% more value to your property, according to the contractors of A+ Elevators & Lifts. These are probably among the list of most useful inventions man ever made. An elevator can be custom-made, depending on what the building needs.
Even During the Ancient Times
Some people may ask, “When and where was this machine really invented?” Based on historical records, Egyptians were already using a prototype elevator. They use this to lift heavy limestone in building their enormous pyramids. Other accounts, meanwhile, claim that the first man-powered elevator used to transport people instead of things was invented in the 18th century.
So Near, Yet So Far
Over time, a few more inventors developed the idea. Instead of manually pulling rope to lift the box, they have used a belt and a steam-powered device to raise or drop it. The steam-powered elevators were later replaced by hydraulic machines in 1870s. A heavy piston moving in a tube supports this hydraulic machine. It is operated by water pressure sourced from the pumps.
Contemporary Designs of Elevators
Modern elevators, though, are attributed to American inventor Elisha Otis. He introduced the freight elevator equipped with a safety feature, in case the cables snap. This made elevators more popular with the public. He later developed it further by adding brakes to the safety system.
Although he did not invent the elevator, his design is where modern elevators were patterned to. This brainchild is what made skyscrapers not just a dream. Without elevators, man would probably crowd the grounds and unable to utilize the air space.
