Do you Know How the Escalator Works Since you Have Been on Escalators So Many Times?

The core components of the escalator are two chains, which revolve around two pairs of gears. At the top of the escalator, a motor drives the transmission gear to rotate the chain ring. Unlike the conveyor belt moving a plane, the chain ring moves a set of steps. The most interesting thing about escalators is the way these steps move. When the chain moves, the steps on the passenger side remain horizontal. At the top and bottom of the escalator, the steps fold over each other to form a platform. This makes it easier to get on and off the escalator.

Each step on the escalator has two sets of wheels, which rotate along two separate tracks. The upper device is connected to a rotating chain and is pulled by a drive gear located on the top of the escalator. The wheels of the other groups just slide along the track and follow behind the wheels of the first group. The two tracks are separated from each other so that each step can be kept horizontal. At the top and bottom of the escalator, the track is in a horizontal position so that the steps are flattened. There is a series of grooves inside each step to connect the two steps before and after it is flattened.

In addition to rotating the main chain ring, the motor in the escalator can also move the handrail. The armrest is just a rubber conveyor belt that circulates around a series of wheels. The conveyor belt is precisely configured to move at exactly the same speed as the steps, making the passengers feel stable.

Escalators are very suitable for providing short-distance transportation. This is because of the high load rate of the escalator. After the elevator is full, other people can only get on the elevator after it reaches the designated floor and returns. On the escalator, as long as one person reaches the upper level, it will make room for others.
