LIFT
ESCALATOR
The " Elevator Or Lift “ Is A Type Of Vertical Transport Equipment That Efficiently Moves People Or Goods
Between Floors Of A Building. Elevator Are Generally Powered By Electric Motors Cables Or
Counterweight Systems Like Hoist To Raise A Cylinderical Piston Like A Jack.
Escalator Is A Moving Staircase – A Conveyor Transport Device For Carrying People Between Floors Of A
Building. The Device Consists Of A Motor -Driven Chain Of Individual, Linked Steps That Move Up Or
Down On Tracks, Allowing The Step Treads To Remain Horizontal.

MAJOR DIFFERENCES BETWEEN LIFT & ESCALATORS?
ELEVATORS
1. Elevator is a lift which accommodate the certain number of people at a time and let them to
move between floors.
2. Elevators are used most of the multi storied buildings such as apartments, offices and bigger
institutions
ESCALATORS
1. Escalators can accommodate more number of people as it continuously moving between the
floors. It is like instead of walking in stair case lets you to top, the staircase brings you to the top.
2. Escalators are primarily used in large people gathering places such as malls, railway station,
etc..,

WHY LIFT/ESCALATOR WERE INVENTED?
1. Rapid Development- Buildings deigned nowadays built vertically due to increased
land cost and population.
2. Comfort-To provide efficient and safe vertical transportation to people in vertical
buildings.
• Special Cases-
• 1. Transportation of patients in hospitals and vertical transportation of handicapped
people.
• 2. To increase working efficiency of offices and large organizations.

DIFFERENT TYPES OF PRODUCTS AVAILABLE IN THE MARKET
DEFINITION | DIFFERENCE | REASON | TYPES | SELECTION CRITERIAS
1. Trade Lift- used in offices, buildings, hotels, etc.
2. Hospital Lift- used in hospitals and treatment centers.
3. Car Lifts- used to lift car in multi - Storey car parks.
4. High Residential Lift- used in flats and other high-rise buildings for efficient transportation of people.
5. Fire Lift-This lift controls a system back in emergency.
Types of Lifts (on basis of USE)
Types of Lifts(on basis of function)
1. Electric Lift- It is basically electro-mechanical enabled gearless traction electric technology to send people to
higher build.
2. Hydraulic Lift-These are powered by piston that travels inside a cylinder. An electric motor pumps hydraulic oil
into the cylinder to move the piston.
3. Pneumatic Lift- The principle operation of the lift is based on the ascending push generated by difference in the
atmospheric pressure on the top of car and under the car. The vacuum required is achieved by turbines
operating as exhaust fans, located at the top of the elevator.

DEFINITION | DIFFERENCE | REASON | TYPES | SELECTION CRITERIAS
1. Parallel Type- These are escalators which are constructed side by side or with some distance
between them. These are usually at metro stations.
2. Multi-Parallel Type- These are the two or more escalators constructed of same nature in parallel.
3. Criss-Cross Type- These are escalators which are constructed keeping the same nature of escalators
on one side.

FACTORS AFFECTING SELECTION OF
PRODUCT:
DEFINITION | DIFFERENCE | REASON | TYPES | SELECTION CRITERIAS
1. Utility- The function must be identified whether lift is for residential,
commercial, or hospital etc.
2. Capacity- This depends on type of building and frequency of access
to lift.
3. Speed- This depends on no. of stops and users.

TECHNOLOGY
• Serial link communication controller
• Advance weight sense
• Connected with elevator companies server which send alert in
case of fault.
• Connected with Building management system
• Password protected specific floor
• Advance encoder for accurate position and perfect floor level
• Automatic cancellation of nuisance calls.
• Diagonal infrared beam which can detect a passenger who is
about to enter in elevator.
• Advance installation for high rise in which lift can be installed
and later on it can be extended to upper floor as per building
progress . It is very useful for high rise construction where they
want to install lift first ( say for 10th story) and increase the lift
floor as per their building progress( 15th, 20th, 25th ……so on). No
need to wait for complete construction of building.
• Jerk less and noiseless riding
• Smooth acceleration and declaration
DESIGN
• Number of floors to be served.
• Floor to floor distance.
• Population of each floor.
• Location of building.
• Specialist service within building.
• Type of building occupancy.
• Maximum peak demand in passengers per
five minute period.
SAFETY
•Safety brakes.
•Door sensors.
•Door closing devices.
•Door restraints.
•Emergency evacuation feature.
•Pit buffers.
•Emergency alarm switches
•Emergency telephones or communications devices
•Emergency lighting

Rounded Handrail Inlet Cap Our
rounded Handrail Inlet Cap
streamlines with the Moving Handrails,
lending a silent elegance to the
boarding and landing areas.
Screw-free Inner Deck
Removing screws from the Inner Deck
side face not only presents an even
softer, more simple look, but also
removes the danger of passengers
snagging their clothes.
Clearly-contrasted Floor Plate
For improved visibility and
smoother passenger flows,
extended areas from the Moving
Handrails feature different pattern
with a clear contrast.
Space Saving
Shortening the Truss by 205mm*
requires less escalator installation
space and increases freedom in
building layout.

TECHNOLOGY USED:
Skirt Guard Lighting*2
Lighting can be provided along
the entire length of the skirt
guard, lighting up the step
demarcation for both visual
effect and passenger safety.
Comb Light
Lighting provided at Comb level
increases illumination, which
further improves passenger
safety around the Step as well as
visual effect.
Handrail Inlet Cap LED Indicator
LED lamps form an arrow to indicate the
escalator’s traveling direction for
boarding, or a No-Entry sign at the
landing areas.
Inlet Sensor
This sensor keeps any passengers or
foreign objects away from the Handrail
Inlet, a warning buzzer and voice
sounding when a person or object
comes close to the Inlet.

SAFETY FEATURES:
Step with Anti-Slip Grooves
Grooves along the corner edge
of each step improve anti-slip
performance and the visibility of
each step for further passenger
safety
Tiered Demarcation Line
Demarcations along both sides
of a step are raised from the
step surface, thereby
preventing passengers from
getting too close to the skirt
guards and preventing clothes
from getting caught between
a step and skirt guard.
Comb with Smaller Angle
Mitsubishi recognizes how critical
the Comb teeth angle is: even a
small gap between the Comb
and Step can result in a serious
accident. Putting our years of
experience and research to full
use, we have made the angle
the smallest it can be (10° to the
horizontal) to keep passengers
and items such as baggage
from stumbling or getting caught
between the Comb and Step.
Brighter Demarcation Color
Attention to the smallest details is
the chief theme of Mitsubishi’s
safety criteria, and the color of
the Demarcation Line is no
exception. The yellow Step and
Comb Demarcation Line comes
as standard and its brightness
has been improved to provide
better visibility of the Step, Comb
and Floor Plate than in our other
models.
