Central-Mid-Levels escalator , 2,600 feet (790 m): in Hong Kong, tens of thousands of commuters travel each work day between Central and the Mid-levels , a residential district hundreds of feet uphill, using this long distance system of escalators and moving walkways It is the world's longest outdoor escalator system (not a single escalator span).
The floor plate provides a place for the passengers to stand before they step onto the moving stairs, flush with the rest of the floor and usually hinged to allow easy maintenance access, while Speech recognition for lift the comb plate lies between the stationary floor plate and the moving step, so named for the cleats on its edge which mesh with the matching cleats on each step (and resemble a comb).

In the first half of the twentieth century, several manufacturers developed their own escalator products, though they had to market their devices under different names, due to Otis' hold on the trademark rights to the word "escalator." New York -based Peelle Company called their models the Motorstair, while Westinghouse called their model an Electric Stairway.
Safety is a major concern in escalator design, as escalators are powerful machines that can become entangled with clothing and other items. LG Innotek and Clearwin claim that their new sterilizer can wipe out 99.99 percent of germs on handrails through a process known as ultraviolet germicidal irradiation (UVGI).
For example, a single-width escalator traveling at about 0.5 metres (1.5 ft) per second can move about 2000 people per hour, assuming that passengers ride single file. At the top and bottom of the escalator, the two tracks converge so that the front and back wheels of the steps are almost in a straight line.

The Toledo -based Haughton Elevator company referred to their product as simply Moving Stairs. In the Park Pobedy station of the Moscow Metro , the escalators are 126.8 m (416 ft) or 740 steps long, and 63.4 m (208 ft) high. An escalator is a moving staircase which carries people between floors of a building.
The handrail is pulled along its own track by a chain that is connected to the main drive gear by a series of pulleys, keeping it at the same speed as the steps. But, it's not only PR people who are guilty of unfocused and irrelevant storytelling (spam), it's also company executives and founders who lose a bit of perspective during the reality and grind of product development.
