Escalators have become an indispensable part of our life.

They are composed of several components, each of which has its own function in the overall operation of the escalator.

The escalator is driven by a motor, which is the main source of power for the escalator. And the motor is connected to a gearbox, which is responsible for converting the motor's rotational motion into an up-and-down motion that propels the escalator. The gearbox is connected to a chain drive system, which is responsible for transmitting power from the gearbox to the escalator steps.

The escalator steps are connected to the escalator step chain, which guide the steps up and down the escalator. The step rollers are connected to a track, which is responsible for keeping the steps aligned as they move up and down.

The track is also connected to a safety switch, which is responsible for stopping the escalator if it senses an obstruction or if the escalator is overloaded.

It is also equipped with lighting fixtures, which provide illumination for the escalator. The lighting fixtures are connected to a timer, which is responsible for turning the lights on and off at predetermined times.

Escalator is also equipped with the handrail, which provides passengers with a means of support while they are riding the escalator. The escalator handrail is connected to a series of sensors, which are responsible for detecting any obstructions in the escalator's path and stopping the escalator if necessary.

Finally, the escalator is equipped with a control panel, which is responsible for controlling the speed and direction of the escalator. It is connected to a series of switches, which are responsible for controlling the speed and direction of the escalator.

There are many other parts that are not mentioned. These components work together to ensure the safe operation of the escalator.Just like the roles we all play in life, connected to each other
