The Core Parts Of The Escalator

The core part of the escalator is two chains, which circulate around two pairs of gears. At the top of the escalator, there is a motor-driven transmission gear to rotate the chain. A typical escalator uses a 100 hp engine to turn the gears. Both the engine and the chain system are installed in the frame, which refers to the metal structure extending between the two floors.

Unlike a conveyor that moves a plane, the chain moves a set of steps. The most interesting place for escalators is the way these steps move. When the chain moves, the steps are kept level. At the top and bottom of the escalator, the steps are folded to each other to form a platform. So that the upper and lower escalators easier.Escalator

Each step on the escalator has two sets of wheels, which rotate along two separate tracks. The upper device (the wheel near the top of the step) is connected to the rotating chain and is pulled by the drive gear at the top of the escalator. The wheels of the other groups just slide along the track, behind the first group of wheels.Escalator

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 orbit is horizontal and flattened. Each step has a series of recesses so that it is connected to the front and rear steps in the flattening process. In addition to rotating the main chain, the escalator in the motor can also move the handrail. The armrest is just a rubber conveyor that circulates around a series of wheels. The conveyor belt is precisely configured so that the movement speed of the steps is exactly the same, making the passengers feel smooth.Escalator
