Project invention

Hello everyone! today I will introduce you to an
escalator

An American, Charles D.
Seeberger, produced the
first commercial moving
staircase to transport
people in the 1890s.

Charles D.Seeberger
1857 –1931

He called this invention
an ʻescalatorʼ, taking
the name from the
Latin word ʻscalaʼ,
which means ʻladderʼ

Escalators
move people
up and down
short
distances.

Lifts do the
same, but
only move a
small number
of people

Escalators have
the capacity to
move a lot of
people at the
same time, and
they can be placed
in the same space
as one might
install a staircase.

A non-functioning
escalator can be
used as a normal
staircase, whereas
many other
conveyances
become useless
when they break
down.

Towards the end of the
nineteenth century,
cities were becoming
more crowded and the
first escalators were
built at railway stations
and in big department
stores so that people
could move about more
quickly

Today we see escalators everywhere.
