Transcript of Project elevators
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.
Harry Waterman invented the steam powered elevator
Archimedes creates first elevator.
Based on pulleys and winches
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.
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.
