Escalators
BY: DAV I D E N C A R N A C I O N
HISTORY
Escalator are a type transportation device that moves people from one level to
another without human physical movement. It’s a moving staircase with steps that
move up or down different levels, that use a conveyor belt and track which keep the
step horizontal for the pedestrians. Thus the escalator began as an amusement and
not as a transportation system that is being use today. The first patent relating to an
escalator-like machine was granted in 1859 to a Massachusetts man for a steam
driven unit. On March 15 1892, Jesse Reno patented his moving stairs or inclined
elevator as he called it.

not change. But the rise and
run of it has change over
time to accommodate
different level of floor height
due to technology.
