In 1852, Elisha Graves Otis invented a safety break that revolutionized the vertical transport industry.
In the event that an elevator’s hoisting rope broke, a spring would operate pawls on the car, forcing them into position with racks at the sides of the shaft and suspending the car in place. Otis’ first commercial passenger elevator soon changed the world’s skyline, making skyscrapers a practical reality and turning the most valuable real estate on its head—from the first floor to the penthouse. -
The first skyscraper was built in Chicago and Otis's Elevator was put in the building to make it possible
This was the first installation of this elevator.he 1913 Woolworth Building (792 feet) boasted 26 elevators; the 1931 Empire State Building (1,250 feet) required 58. With new and taller buildings, business at the Otis Elevator Company, later run by Otis's sons, rose steadily. -
Otis developed the gear-less traction system involving cables and electricity that would become the most common way to run an elevator
Elevator, also called lift, car that moves in a vertical shaft to carry passengers or freight between the levels of a multistory building. Most modern elevators are propelled by electric motors, with the aid of a counterweight, through a system of cables and sheaves (pulleys). -
Otis invented an elevator that would become the general design of todays elevators.
The gearless traction electric elevator
could be employed in buildings of
any height and operated at much
higher speeds than steam-powered
elevators. -
57 elevators in the largest buildings.
These elevators typically operate at speeds from 38
to 152 meters (125-500 ft) per minute
and carry loads of up to 13,600
kilograms (30,000 lb). An electrically
controlled brake between the
motor and the reduction unit stops
the elevator, holding the car at the
desired floor level. -
The Otis's Company
The Otis Elevator Company is an American company that develops, manufactures and markets elevators, escalators, moving walkways and related equipment. A pioneer in its field, Otis is the world's largest manufacturer of vertical transportation systems, principally focusing on elevators, moving walkways and escalators. -
The outcome of Otis's invention of the Elevator.
Otis's company is the worlds leading elevator manufacturer. As buildings begin to rise to new heights, so does the technology of elevators and new possibilities for America. Because of his invention upgraded and new and improve elevators are made.
