LIFT,ESCALATOR AND MOVING WALKS
TRANSPORTATION SYSTEM
IN HIGH RISE BUILDINGS

WHAT IS LIFT?
A vertical transport equipment that efficiently moves people between
floors (levels, deck) of a building, vessel or other structure.
Generally powered by electric
motor that drive by traction cable and
counterweight systems like a hoist or
hydraulic pump.
Open Lift (bubble type)
Closed Lift (typical type)

•They use an underground cylinder
•common for low level buildings with 2–5
floors (up to 6–8 floors)
•have speeds of up to 200 feet/minute (1
meter/second)
HYDRAULIC LIFT
A lift where the vertical movement is
done by hydraulic force.
GLASS LIFT
• Give passengers a visually stimulating
ride between floors.
• The car walls must be constructed with
laminated glass
•The glass lift consist of entrance area and
a viewing area

Passenger elevators should be located at the circulation core of the building
and be grouped into banks when this is necessary and desirable.
• The required umber of elevators is determined by:
Building type
Building height
Number of stops
Floor use
Passenger volume
PASSENGER ELEVATORS
Elevator designed to carry goods, rather than
passengers.
Freight elevators are typically larger and capable of
carrying heavier loads than a passenger
elevator, generally from 2,300-4,500 kg.
GOODS ELEVATORS

Strecher elevator also cater to the health sector by
providing specialized range of Stretcher Elevators
suited for application in hospitals, health centers
and other similar places
STRECHER ELEVATOR
CAPSULE ELEVATORS
Capsule Elevators act as Architectural highlights on
prestigious buildings. They can be called the
ornaments of a building as they enhance its beauty
and bring life into it

A car elevator is installed where ramps are considered
space-in conservative.
Car elevators are usually used in parking the vehicles at
different floors, automobile show rooms, automobile
service centers etc.
Panoramic elevators , panoramic lift are designed
basically for malls and other commercials buildings.
It has an overlook over other elevators
AUTOMOBILE ELEVATORS
PANORAMIC ELEVATORS

FIREMAN'S LIFT
•For buildings having height of 15m or more
described below :
•Lift car floor area of not less than 1.44 sq.m
• Loading capacity of not less than 544 kg (8
persons).
•Lift landing doors shall have minimum fire
resistance of two hours.
•The lift speed shall be 1.0 m/s or more
•Reachable time to the top floor from the ground (or
entrance) floor within 60 seconds.

Machine room-less (MRL) elevators
• Most of the components fit within the shaft containing the elevator car;
and a small cabinet houses the elevator controller. Other than the
machinery being in the hoistway, the equipment is similar to a normal
traction elevator.
• Benefits
• Can operate at faster speeds than hydraulics but not normal traction
• Creates more usable space
 Use less energy (70-80% less than hydraulic elevators)
 Uses no oil
 Slightly lower cost than other elevators
 Units.

An escalator is a moving staircase –
a conveyor transport device for
carrying people between floors of a
building.
WHAT IS ESCALATOR?
•Designed on an incline of 27.3, 30, 35
degrees.
•If the height is more than 6m than
incline of 27.3 should be given
•The speed of the escalator, shall
not be more than 0.63 m/s for 30o
angle of incline
and 0.50 m/s for 35o angle of
incline.

Types of escalators

7 lighting under upper and lower landing steps.

UP” ESCALATOR NEXT TO STAIRCASE : It
is preferred that staircases be located
adjacent to the escalator if the escalator is
the primary means of transport between
floors.
30° inclination This inclination
provides the highest traveling
comfort and maximum safety for
the user.
35° inclination The 35° escalator is
the most efficient solution as it
requires less space and can be
implemented more cost-effectively.
However, this inclination is
perceived as too steep if rises
exceed 5 m – particularly in
downward travel.

COMPONENTS OF THE ESCALATOR:
• Landing Platforms.
•Truss.
•Tracks.
•Steps.
•Handrail.
•Escalator Exterior (Balustrade).
•Drive system.
•Auto-Lubrication System.
•Braking system.
•Safety devices.
•Electrical & Control Systems.

Handrail-
•the handrail width not more than 75mm
BALUSTRADE-
DECK BOARD- These are used for preventing
clothing from getting caught and other such
problems.
balustrade
deck board
•operating speed is less than 0.35 m/s
•The thickness of the glass
shall not be less than 6 mm.
•Height 680 mm vertically above the
nose line of the steps,
•Each moving handrail height not less
than 300 mm.

TRUSS –
•The truss is a hollow metal structure
•that bridges the lower and upper landings.
• The ends of the truss are attached to the top
and bottom landing platforms via steel or
concrete supports.
FLOOR PLATE-
•flush with the finished floor
• in front of the escalator shall be a
minimum of 3 m.
•STEPS-
•Trade shall not be less than 400 mm
•Riser shall not be more than 220 mm.
•front and back edges of the steps are each connected to two wheels.
steps

• LANDING PLATFORMS:
• 2 plat form
• Tracks:
• The track system is built into the truss to
guide the step chain, which continuously
pulls the steps from the bottom platform
and back to the top in an endless loop.
COMB PLATE
• The comb plate is the piece between the
stationary floor plate and the moving step.

For a speed of 0.5m/s the theoretical capacity
is:
•600mm step width -4500 persons per hour
•800mm step width -6750 persons per hour
•1000mm step width -9000 persons/hour
•Standard transportation speed ranges
between 0.5 to 0.65m/s
•Minimum head room shall not be
less than 2.3 m.
•escalators having a vertical rise
not more than 6 m.

WIDTH OF ESCALATOR CROSS-SECTION OF AN ESCALATOR

ESCALATOR WIDTH
In accordance with a worldwide standard,the width of
the step to be used is 60 cm
(for one person), 80cm (for one-to-two people) and
100cm (for two people width)

SAFETY
• Safety is also major concern in escalator design.
• Fire protection of an escalator floor-opening may
be provided by adding automatic sprinklers or
fireproof shutters to the opening, or by installing the
escalator in an enclosed fire-protected hall.
• To limit the danger of overheating, adequate
ventilation for the spaces that contain the motors
and gears must be provided.
• It is preferred that a traditional staircase be located
adjacent to the escalator if the escalator is the
primary means of transport between floors.

Escalators construction

• A moving staircase used to
carry people from one floor of
a building to another.
• Can be placed in the same
physical space as one might
install a staircase.
• Escalators are quite convenient
due to the fact that they are
quite safe in case of a
emergency.
• On top of that a escalator can
transport a large amount of
people at the same time.
• Can always walk up on one side
to get to the top faster if you
want.
• Escalator takes up more
space because it is built in
a incline which stretches
out a certain length
depending on how high it
needs to reach.
• It is not safe to take a
stroller, walker or even a
cart on an escalator.

Moving Walk-
is a slow moving conveyor mechanism that
transports people across a horizontal or
inclined plane over a short to medium
distance.
. They are often installed in pairs, one for
each direction
• Used for carrying passengers,
horizontally
•An incline up to a maximum of 15
degree.

1. According To Inclination Angle
2. Horizontal and Inclined Walkways
a- Zero degrees inclination “Horizontal” Moving Walkways.
b- Up to 15 degrees inclination “Inclined” Moving Walkways.
Types of Moving walkways

•normal handrail height not less than
300 mm
•Operating speed is less than 0.35 m/s or the
width is no more than 530 mm.

Proper inclination Moving walks
• Inclinations of 10°, 11° and
12° are the common
international standard for
inclined moving walks.
• Users find that a 10°
inclination provides the most
comfortable ride. A 12°
inclination is used whenever
the space available is limited.
• Horizontal moving walks can
generally be provided for
inclinations between 0° and
6°.

According To the Flat Moving Surface
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.
Pallet Type Moving walkwaysMoving Belt
These are generally built with mesh metal belts or rubber walking surfaces over
metal rollers.
Moving Belt Moving Walkway

According To the Speed
Slow- speed Standard type
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.
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.
High-speed walkways

• 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:
• 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.

• Zoos
Similar to museums, some zoological park exhibits have a moving walkway to ease
guests through an animal display or habitat.
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:

• 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.
• Public transport
Moving walkways are useful for remote platforms in underground subway/metro
stations, or assisting with lengthier connections between lines, for example:

Underground subway moving walkway
Metro stations moving walkway
• Skiing
• Moving walkways known as Magic
carpets are also used in ski resorts

• Supermarkets
• Hyundai
