How An Escalator Work:
The main part of an escalator is a pair of chains which looped around two pairs of gears.
See the picture above as an example (one is for step rollers and one is for handrail).
There is an electric motor at the top that turns the drive gears.
The motor and the chain systems are house inside these metallic structure which they call structure truss.
The machine will create a flat platform at the top and bottom of the escalator.
So it will be easier for you to safely step in the escalator and safely step out the escalator.
The upper steps are connected to rotating chain (based on the picture above) and are pulled by the top sprocket gear.
The bottom sprocket will roll along in a separate track that’s spaced precisely to ensure that steps always remain level.
The step chains in an escalator is the one that move a series of steps.
The handrail is basically to make your ride more stable.
