efficiently moves people or goods between floors
or levels of a building, vessel, or other structure.
WHAT IS LIFT?

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

sign shall be in letters not less than 12 mm high.
•control buttons shall be at least 19 mm min
dimensions.
•standby power within 60
seconds after
failure of normal power.

11. LIFT,ESCALATOR AND MOVING WALKS
LIFT SHAFT: Constructed
with reinforced concrete.
counterweight :
•To grip the lift car
• Reduce the power of
generator
• Reduce the brake to
stop the car lifts
GEARLESS MOTOR
GUARD RAIL: hold the
lift from crashing down
if the rope break.

12. LIFT,ESCALATOR AND MOVING WALKS
•Lift pits having depth more than 1.6 m
shall be provided
•The width of lift machine room shall be equal to be lift
(minimum of 2500 mm)

under the lifting beam
•the trap door shall not be less than 1.0 m x 1.0 m
SHAFT PIT – the bottom end of the
shaft is called pit.
•machine room entrance is less than 1.5 m

18. LIFT,ESCALATOR AND MOVING WALKS
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.

19. LIFT,ESCALATOR AND MOVING WALKS
TYPES OF ESCALATOR:
PARALLEL: These type of
escalator go up and down
simultaneously.
MULTI PARALLEL
CRISS-CROSS: They stacks the escalators that go in
single direction and reduces structural space
requirement.

20. LIFT,ESCALATOR AND MOVING WALKS
TYPES OF ESCALATOR:
SPIRAL TYPE ESCALATORS: These are
used to enhance the architectural beauty
and to save the space.
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.
