facts about the invention
elevator by Elisha
Graves Otis in 1852.
AT A GLANCE:
In 1852 Elisha Graves Otis, invented the first safety brake for
elevators. With his installation of the first safe elevator in 1853 he
literally started the elevator industry. His invention enabled buildings
– and architects’ imaginations – to climb ever skyward, giving a new and
bolder shape to the modern urban skyline. Today you can ride an Otis
elevator with confidence, knowing that it represents 150 years of
experience in both safety and quality.

Imagine the skyline of a modern city if the elevator did not exist.
Buildings would be limited to five or six stories. Most of the architecture
of the 20th and 21st century would be impossible. Office towers, hotels and
high-rise apartments would hardly stand in their present form.
The need for vertical transport is as old as
civilization. Over the centuries, mankind has employed ingenious forms of
lifting. The earliest lifts used man, animal and water power to raise the
load. Lifting devices relied on these basic forms of power from the early
agricultural societies until the dawn of the Industrial Revolution.
From ancient times through the
Middle Ages, and into the 13th century, man or animal power was the driving force behind
hoisting devices. In ancient Greece, Archimedes developed an improved
lifting device operated by ropes and pulleys, in which the hoisting ropes
were coiled around a winding drum by a capstan and levers. By A.D. 80,
gladiators and wild animals rode crude elevators up to the arena level of
the Roman Coliseum.
Medieval records contain numerous drawings of hoists lifting men and
supplies to isolated locations. Among the most famous is the hoist at the
monastery of St. Barlaam in Greece. The monastery stood on a pinnacle
approximately (200 ft) above the ground. Its hoist, which employed a basket
or cargo net, was the only means up or down.
The first elevator designed for a
passemger was built in 1743 for King Louis XV at his palace in
France. The one-person contraption went up only one floor, from the first to the second.
Known as the "Flying Chair," it was on the outside of the building, and was
entered by the king via his balcony. The mechanism consisted of a carefully balanced
arrangement of weights and pulleys hanging inside a chimney. Men stationed inside the
chimney then raised or lowered the Flying Chair at the king's command.
By 1850 steam and hydraulic elevators had been introduced,
but it was in 1852 that the landmark event in elevator history occurred: the invention of
the world's first safety elevator by Elisha Graves Otis. The first passenger elevator was installed
by Otis in New York in 1857. After Otis' death in 1861, his sons, Charles and Norton,
built on his heritage, creating Otis Brothers & Co. in 1867. By 1873 over 2,000 Otis
elevators were in use in office buildings, hotels and department stores across America,
and five years later the first Otis hydraulic passenger elevator was installed.
The Era of the Skyscraper followed.... and in 1889 Otis revealed the
first successful direct-connected geared electric elevator machines.
In 1898 overseas business had added to the company's growth,
and Otis Brothers merged with 14 other elevator entities to form the Otis
Elevator Company. In 1903 Otis introduced the design that would become the
"backbone" of the elevator industry. The gearless traction electric
elevator, engineered and proven to outlast the building itself. This ushered
in the age of high-rise structures, ultimately including New York's Empire
State Building, Chicago's John Hancock Center, and Toronto's CN Tower.
Otis is part of United Technologies Corporation, a Fortune 500 company and
world leader in the building systems and aerospace industries. With 1.7
million Otis elevators and 110,000 escalators in operation, Otis touches the
lives of people in more than 200 countries around the world.

The skyscraper, that most durable symbol of modernity, would not have been possible
without the elevator, and the elevator as we have come to know it is largely the product
of the company that Elisha Otis founded in the 1850s.

The Elevator Escalator Safety Foundation
Their mission is to educate the public on the safe and proper use of elevators,
escalators and moving walks through informational programs.
Internet Elevator Service
e*Service combines REM data with technicians’ reports to give customers
access to information about their elevators and escalators directly over the
Internet. Internet monitoring through e*Service helps customers to better
manage their buildings by giving them access to reports showing trends in
uptime, service call types and technicians’ documentation—anytime, anywhere.
HOW IT WORKS:
Engineers claim that all machines can be reduced to the fundamental
components known to the early /Greeks - the lever, the wheel and axle, the
pulley, the inclined plane/wedge and the screw.
