escalator
Automatic escalators are ideal passenger transport means for public places e.g.
metro, railway station, port, department store, office building, hotel, and restaurant
and so on. It can transport passengers continually from one floor to another or
trans-floor. It can operate both up and down. It can not only transport passengers but
also beautify the environment.
The traction machine of chain driven automatic escalator lies in the upper horizontal
truss. The traction machine turns through the main axle driven by two rows of
chains. The main drive sprocket drives the steps by the step traction chain to run in
cycles along the step track of the automatic escalator. At the same time, the handrail
driving chain and hand driving chain wheel drives the friction wheel of the handrail
drive axle by the double-row of chains. There is enough friction between the friction
wheel and handrail by adjusting the spring of the pressing belt device for the sake of
the synchronous running of the handrail and steps.
