Escalator work
Dec 29, 2016

Escalators are two core components of the chain, which circulates around two sets of gears turning. At the top of the escalator, there is an electric motor-driven gear, with turning chain ring. Typical of escalator using a 100 HP engine to rotate the gear. Engine and chain systems are installed on the truss, frame refers to the metal structure extending between two floors.


Different from the conveyor belt moves a plane, chain circle is a set of stairs. Escalators are the most interesting places these steps move. Chain moves, stairs remain level. At the top and bottom of the escalator, stairs collapsed with each other to form a platform. So that the up and down escalators is easier.


Every step on the escalator has two sets of wheels, rotating along two separate tracks. Upper unit (near the top of the steps of the wheels) connected with the rotation of the chain, and at the top of the escalator-driven gear driven. Another set of wheels just slide along the track, behind in the first set of wheels.


Two tracks spaced, so that each step is level. At the top and bottom of the escalator rail horizontal position, so that step flat. There are a series of grooves within each step, so that during the flattening process and after two steps are connected together.


In addition to turning chain ring, the escalator in the motor can move the armrest. Armrest just a round rubber conveyor belt loops through a series of wheels. The conveyor belt is precisely configured, to speed of the steps are exactly the same, make users feel smooth.


Escalator system is not making up dozens of stories like the elevator, but was adapted to provide short-distance transportation. This is because the high load rate of escalator. Lift after full, had to wait after it reaches the specified level and returns on other people can lift. On the escalator, as long as a person reaches the upper would make positions for others.
