How do Escalators Work?

The escalator has a structural support, called the “Truss” and contains all the installed machinery. The propulsion system consists of a pair of chains by the name of “Step Chains”. These loop around two pairs of gears, in the lower and upper sections. They connect to the gearbox of the motor by a chain called “Motor Chain”. The steps chains hold the steps and move when the step chains turns.
On both sides of steps there are shelters for user safety called "Balustrade", made of tempered glass or stainless steel or a combination of both. On the balustrade, there is a belt with a rubber cover reinforced inside by a metal-insert that helps the user balance him or herself, called the “Handrail”.
