Walkalator
1. is a slow moving conveyor mechanism that transports people across a
horizontal or inclined plane over a short to medium distance. Moving
walkways can be used by standing or walking on them. They are often
installed in pairs, one for each direction.
2. The first moving walkway debuted at
the Worlds Columbian Exposition of 1893,
in Chicago, Illinois.
Two Divisions:
1. passengers were seated
2. riders could stand or walk
The Great Wharf, Moving Sidewalk
3. Six years later a moving walkway was also
presented to the public at the Paris
Exposition Universelle in 1900
Three Elevated Platforms:
1. stationary
2. moderate speed
3. six miles an hour

4. The first commercial moving walkway in the
United States was installed in 1954 in Jersey
City, NJ, inside the Hudson & Manhattan
RailroadErie station) at the Pavonia Terminal
• Named the "Speedwalk“
• built by Goodyear
• it was 277 ft (84.5 m) long
• moved up a 10 percent grade at a speed of 1.5 mph
(2.4 km/h)
5. The first moving walkway in an airport was installed
in 1958 at Love Field in Dallas, Texas.

Walkways.
b- Up to 15 degrees inclination “Inclined” Moving
Walkways.

8. 2. According To the Flat Moving
Surface
a- Pallet Type
A continuous series of flat metal plates mesh
together to form a walkway. Most have a metal
surface, though some models have a rubber
surface for extra traction.
10. b- Moving Belt
These are generally built with mesh metal belts
or rubber walking surfaces over metal rollers.
The walking surface may have a solid feel or a
"bouncy" feel.
Both types of moving walkway have a grooved
surface to mesh with comb plates at the
ends. Also, all moving walkways are built with
moving handrails similar to those on
escalators.
12. 3- According To the Speed
a- Slow- speed Standard type
The speed of these walkways is determined by
the need for safety upon entry and exit, which
generally limits it to approximately half normal
walking speed, or 30–40m/min. The slow
speed of the walkway causes impatience, and
passengers often walk on the walkway itself or
on the adjacent floor rather use the slower
walkway.
13. b- High-speed walkways
Using the high-speed walkway is like using any other moving
walkway, except that for safety there are special procedures to
follow when joining or leaving.
On entering, there is a 10 m acceleration zone where the
"ground" is a series of metal rollers. Riders stand still with both
feet on these rollers and use one hand to hold the handrail and
let it pull them so that they glide over the rollers. The idea is to
accelerate the riders so that they will be traveling fast enough
to step onto the moving walkway belt. Riders who try to walk on
these rollers are at significant risk of falling over.
At the exit, the same technique is used to decelerate the riders.
Users step on to a series of rollers which decelerate them
slowly, rather than the abrupt halt which would otherwise take
place.
16. The moving walkways are identical to
escalators in the basic components of their
construction, but they differ in the following:
• Moving walkways may run horizontally or on
an incline of up to 15 degrees.
• The flat moving surface of the moving
walkways may consist of a continuous rubber
belt or a series of jointed treads.
19. Airports
Moving walkways are commonly used in
larger airports, as passengers – often with heavy
luggage in tow – typically need to walk
considerable distances. Moving walkways may be
used:
• in passageways between concourses and the terminal
• within particularly long concourses
• as a connector between terminals, or
• as access to a parking facility or a ground transport
station.

Airport, United States.

international terminal at Los Angeles
International Airport in Los
Angeles, California, United States.
21. Museum exhibits
Moving sidewalks may be used:
• to ensure that a museum exhibit is viewed in a
certain sequence
• to provide a particular aesthetic effect
• to make sure the crowd moves through at a reliable
pace.
22. The National Gallery of Art in Washington, DC uses a
moving walkway to connect the two main galleries.
23. Zoos
Similar to museums, some zoological
park exhibits have a moving walkway to ease
guests through an animal display or habitat.
• An aquarium at the Mall of America does this with a
moving walkway made up of specially rounded pallets
that enable it to change directions and route
• The San Diego Zoo uses moving ramps to help guests
ascend steep grades.
25. Theme parks
Some amusement park rides, such as continuous-
motion dark rides like Disney's Haunted Mansion, make use of a
moving sidewalk to assist passengers in boarding and
disembarking rides and attractions. Some examples include:
• the Ultra Twister, a roller coaster at the now
closed Astroworld in Houston, Texas. (It had a moving walkway with no
handrail for passengers to step on prior to boarding their car. The
walkway would move at the same speed as the approaching cars,
allowing passengers completing the ride to step off and for boarding
passengers to enter the car. A loudspeaker announced "Moving
conveyor, please watch your step" to warn of the moving walkway.
• the exit from the Space Mountain attraction at Walt Disney World has a
long moving walkway which changes inclination multiple times.
• the exit from the Pirates of the Caribbean attraction at Walt Disney
World has an inclined moving walkway leading towards a gift shop.
• the exit from the Haunted Mansion attraction at Walt Disney World has a
straight moving walkway which leads to the ride's exit.

27. Theatre
The Phantom of the Opera by Andrew
Lloyd Webber uses a travelator in the number
'The Phantom of the Opera' (act one, scene
six), to give the illusion the Phantom and
Christine are traveling the catacombs below the
Paris Opera House a great distance to the
Phantom's lair on the subterranean lake.

29. Public transport
Moving walkways are useful for remote platforms in
underground subway/metro stations, or assisting with
lengthier connections between lines, for example:
• Waterloo Underground Station in London, United Kingdom, and
between Central and Hong Kong stations on Hong Kong Island, Hong
Kong, as well as between Tsim Sha Tsui and East Tsim Sha Tsui
sitations in Kowloon, Hong Kong.
• Similar walkways exist in Singapore's Bugis MRT Station, Dhoby Ghaut
MRT Station and Serangoon MRT Station. In Glasgow,
Scotland's Buchanan Street subway station a moving walkway is used to
connect the Subway station with Glasgow Queen Street Station.
• In Toronto, Canada, a moving walkway existed between Spadina station
on the Bloor-Danforth subway line and Spadina station on the Yonge–
University–Spadina line. Installed in 1978, this series of moving
walkways has since been removed (2004) and patrons are now required
to walk between the stations.
31. Skiing
Moving walkways known as Magic
carpets are also used in ski resorts. Skiers can
place their skis on the walkway which is
designed to provide a strong level of grip.
Since the walkways cannot be too steep and
are slow compared to other aerial lifts, they are
used especially for beginners or to transport
people over a short uphill distance, such as to
reach a restaurant or another lift's station.
Moving walkways can also be found
at chairlifts' entrances to help passengers in
the boarding process.
