A vertical transport equipment that efficiently moves people
between floors (levels, deck) of a building, vessel or other
Generally powered by electric motor, which is driven by
traction cable and counterweight systems like a hoist or
How elevators work?
PUSH VS PULL
Push = Hydraulic Pull = Traction
Machine or Drive system
Rapid development : buildings design nowadays built vertically /higher
because of high land cost.
Basic needs : to bring building user from one level to higher level in building
Comfort needs : working efficiency for office building or large
UBBL : building with more than 6 storey must provide lifts system.
Fire requirements : provide fire lift to be used during fire.
Means of moving an Elevator
Traction elevators (Geared and gear-less) : Geared traction machines are driven by
AC or DC electric motors. Geared machines use gears to control mechanical movement
of elevator cars by "rolling" steel hoist ropes over a drive sheave which is attached to a
gearbox driven by a high speed motor.
Gear-less traction machines are low speed, high torque electric motors powered either
by AC or DC. In this case, the drive sheave is directly attached to the end of the motor.
Hydraulic elevators : Conventional hydraulic elevators, They use an underground
cylinder, are quite common for low level buildings with 2–5 floors (sometimes but
seldom up to 6–8 floors), and have speeds of up to 200 feet/minute (1 meter/
Traction hydraulic elevators : The traction-hydraulic elevator has overhead
traction cables and counterweight, but is driven by hydraulic power instead
of an overhead traction motor. The weight of the car and its passengers,
plus an advantageous roping ratio, reduces the demand from the pump to
raise the counterweight, thereby reducing the size of the required machinery.
Climbing elevators : A climbing elevator is a self-ascending elevator with
its own propulsion. The propulsion can be done by an electric or a
combustion engine. Climbing elevators are used in guyed masts or towers, in
order to make easy access to parts of these constructions, such as flight
safety lamps for maintenance.
Categories (Function based)
Trade Lift : Crucial to the good performance to clients of the trade building.
Hospital Lift : used in hospital & treatment centres.
High residential Lift : For high rise residential buildings such as flat/apartment.
Institution Lift : Used in library, office, classroom or lecture hall located at high
Store Lift : Used to transport heavy goods
Car Lift : Used specifically to lift a car in multi storey car park or showroom.
Robert Schindler established the company in 1874 in Switzerland.
Company began manufacturing elevators in 1889.
Did not have a local market base in India until 1950 by appointing a local
Alfred N Schindler took over the company in 1987; becoming the 4th
generation in line.
1998 : Schindler increased revenue worth $6.6 billion around the world.
Company has over 38,000 employees in 97 subsidiaries.

Destination Technology : Our destination control system delivers
smart mobility. It offers personalised service and access control,
and unmatched performance in new and existing buildings.
An escalator is a moving staircase, a conveyer 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.
Escalators are used around the world to move pedestrian traffic in places where
elevators would be impractical such as shopping malls, airports, hotels and public
They can be placed in the same physical space as one might install a staircase. They
can be used to guide people toward main exits or special exhibits.
Schindler 9300 AE : The flexible mobility solution for mid-rise
commercial and transport facilities. It is the versatile escalator, ideally
suited for commercial applications, it can also be adapted for transport
applications including stadiums, airports and exhibition halls.
Schindler 9700 : A high-performance escalator system for high-
traffic public spaces. It provides mobility solutions for large public
spaces with high-traffic demands such as airports, subways and
