VII. How it’s work

At the beginning I would like to say that before we face these idea we didn't know how is the escalator work but when we started working on the project under the supervision of Dr. Emad we found it the Way is too easy and smooth you should know that There are four parts in the bask equation which is the outer tube, inner tube, stairs and the meeting point.
There's a piece fixed in this game is not moving which is the outer tube While the movement of the inner tube, there will be a meeting point in the two tracks will be a step in the middle of it .
We did not know before how beautiful these are, in a move the stairs Now we can analyze any movement of any kind of different escalator so, within technology and renewed development of the human mind and creates beautiful things life has to facilitate the automatic

However, we know the benefits of escalators are many. They have the capacity to move large numbers of people, and they can be placed in the same physical space as one might install a staircase.

And because Spiral escalators take up much less horizontal space than straight escalators. However, early spiral designs were failures. For example, one spiral escalator constructed by Reno in conjunction with William Henry Aston at London's Holloway Road Underground station in 1906 was dismantled almost immediately and little of the mechanism survives. The Mitsubishi Electric Corporation has developed successful commercial designs and has manufactured curved and spiral escalators since the 1980s.
