Transcript of Project elevators

~The earliest record of an elevator was documented to be around 236 BC made by Archimedes. However; the first elevator intended for passenger use was made in 1743; and was made by an unnamed group of french engineers/inventors, who constructed this device for King Luis XV at Versailles. It was nicknamed the flying chair.
Very unsafe, not very advanced.
The passenger elevator required a substancial amount of knowledge of mechanical engineering, and product improvment, and design. This is because, the initial foundation of the mechanics of an elevator, or based upon simple machines, such as pulleys. This concept which had been applied throughout history had to be later innovated for the passenger elevator. As the original early elevator, was too inefficient, and had little capabilities in terms of speed, and carry capacity.

1903
1880
1850
Harry Waterman invented the steam powered elevator

Archimedes creates first elevator.
Based on pulleys and winches
1853
Alisha Otis invents first safety brake system

Siemens introduced first electric power elevator

USA: Traction type current elevator
uses traction power to connect a car to a counterweight by a rope and pulley.



Present
Elevator Timeline
1835:
The "Teagle". Belt driven elevator. Used a counterweight for extra power.
1846: Hydraulic crane.

Water pump supplied water pressure to a plunger inside a vertical cylinder

Use of counterweights increased lifting power

Allowed heavier weights to be lifted
Some effects that the elevator had around the world, were
-stepping stone for making skyscrapers, and tall buildings
-allowed for ease of transportation for the disabled
-In directly helped control over population.
-Major energy consumer.
