SOCIAL IMPACT

Escalators have transformed societies in many different parts of the world.

ENVIRONMENTAL IMPACT

• A common escalator that has a 7.5 horsepower motor,rising 15 feet above the ground,kept running 14 hours a day, six days a week will consume almost 7500 kilowatt hours (kwH) of electricity in a year.

• A larger escalator will consume almost 31000 kwH of electricity a year.

ECONOMIC IMPACT

• The world's first commercial escalator was made at the Otis factory in New York.

• Charles Seeberger, the redesigner of the escalator, sold his patent rights to the Otis Elevator Company in 1910.

OPERATIONAL IMPACT

• Escalators help customers in  supermarkets (e.g. Giant) to transport their trolleys from one level to another, allowing them to shop  more easily.

• Escalators transport a larger number of people compared to the elevator which has limited/ restricted space.
