  1. The core components of escalators are two chains, which revolve around two pairs of gears. At the top of the escalator, there is an electric motor drive gear, to turn the chain. A typical escalator USES a 100-horsepower engine to turn gears.
  2. The engine and chain system are installed in the truss, which refers to the metal structure extending between the two floors.
  3. Different from the conveyor belt moving a plane, the chain is moving a set of steps.The most interesting thing about escalators is the way these stairs move.When the chain moves, the steps remain horizontal.At the top and bottom of the escalator, the steps fold each other to form a platform.This makes it easier to go up and down escalators.
  4. Each step on the escalator has two sets of wheels, which move along two separate tracks.The upper device (the wheel near the top of the steps) is connected to the rotating chain and driven by the drive gear at the top of the escalator.Other groups of wheels just slide along the track, following the first set of wheels.
  5. The two tracks are separated from each other so that each step can be kept level.At the top and bottom of the escalator, the track is in a horizontal position, thus flattening the steps.There are a series of grooves inside each step so that they can be connected to the front and back steps in the process of flattening.
  6. In addition to turning the main link, the motor in the escalator can move the handrail.The handrail is just a rubber conveyor belt revolving around a series of wheels.The conveyor belt is precisely configured so that it can move at exactly the same speed as the steps, allowing the user to feel smooth.
  7. Escalator system does not lift people up to dozens of floors like elevators, but it is suitable for short distance transportation.This is because of the high load rate of escalators.When the elevator is full, it must wait until it reaches the designated floor and then returns to the elevator.On escalators, as long as one person reaches the top, they make room for others.
