Lift is a type of vertical transport equipment that efficiently moves people or goods between floors or levels of a building, vessel, or other structure.

WHAT IS LIFT?

TYPES OF LIFTS


•Open Lift (bubble type)

•Closed Lift (typical type)

Hydraulic lift

Passenger lift Goods lift

Strecher liftCapsule lift Glass lift


•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 LIFTA 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

Goods lift

LIFT,ESCALATOR AND MOVING WALKSPASSENGER LIFT:A lift designed for the transport of passengers.

LIFT,ESCALATOR AND MOVING WALKSFIREMAN'S LIFT•For buildings having height of 15m or moredescribed 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.


Dumb waiter

•total inside ,height and capacity not exceeding 0.9 m2, 1.25 m and 225 kg• used for carrying materials and no person.

DUMB WAITER


HOSPITAL LIFT

•minimum inside platform area 1275 mm wide x 2000mm long•minimum clear opening width of 1050 mm,•an ambulance stretcher (minimum size 600 mmwide x 2000 mm long) in its horizontal position.


Components of lift• Control room • Guides • Lift car • Lift car door• Car rail• Counter weight • Control panel • Lift pit • Buffer • Hoist way • Hoist rope • Ventilation window• Flexible cable• Drive crank

LIFT,ESCALATOR AND MOVING WALKS LIFT CAR :Platform where passengers or goods is transported.

•Passenger elevators should be located at the circulation core of the building.

•minimum width and depth of the car shall be 2000 mmand 1291 mm.(for wheel chair)

•The rails shall be at least 38 mm clear of the walls• nominal height of 800 mm from the floor.

•Height of the entrance to the lift car shall not be less than 2 m.

LIFT,ESCALATOR AND MOVING WALKS•alarm button and emergency stop switch shall be at a height of 890 mm,•highest floor button no higher than 1.37 m from the floor.•letters or numbers shall be a minimum of 15 mm high

•in fire emergency, DO NOT USE LIFT. USE EXIT STAIRS. This 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 afterfailure of normal power.


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.


• 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)•The height shall not be less than 2.30 m throughout 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

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 inclineand 0.50 m/s for 35o angle of incline.

LIFT,ESCALATOR AND MOVING WALKSTYPES 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.

LIFT,ESCALATOR AND MOVING WALKSTYPES 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.


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.

LIFT,ESCALATOR AND MOVING WALKSHandrail-

•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 glassshall not be less than 6 mm.•Height 680 mm vertically above thenose line of the steps,

•Each moving handrail height not less than 300 mm.

LIFT,ESCALATOR AND MOVING WALKSTRUSS –•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


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.


Moving Walk-A power driven, horizontal or inclined, continuously moving conveyor• used for carrying passengers, horizontally•an incline up to a maximum of 15 degree.


•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.
