  2. LIFT,ESCALATOR AND MOVINGWALKS WHAT ISLIFT? Lift is a type of vertical transport equipment that efficiently moves people or goods between floors or levels of a building, vessel, or otherstructure. • Open Lift (bubbletype) • Closed Lift (typicaltype) TYPES OFLIFTS Passengerlift Goodslift Strecherlift Glasslift Capsulelift Hydrauliclift

  3. LIFT,ESCALATOR AND MOVINGWALKS • HYDRAULICLIFT • A lift where the vertical movement is done by hydraulicforce. • They use an undergroundcylinder • common for low level buildings with 2–5 floors (up to 6–8floors) • have speeds of up to 200 feet/minute (1 meter/second) • GLASSLIFT • give passengers a visually stimulating ride betweenfloors. • The car walls must be constructedwith • laminated glass • the glass lift consist of entrance area and a viewingarea

  4. LIFT,ESCALATOR AND MOVINGWALKS PASSENGER LIFT:A lift designed for the transport ofpassengers. Goodslift

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

  6. LIFT,ESCALATOR AND MOVINGWALKS • DUMB WAITER • total inside ,height and capacity not exceeding 0.9 m2, 1.25 mand 225kg • used for carrying materials and noperson. Dumbwaiter

  7. LIFT,ESCALATOR AND MOVINGWALKS • minimum inside platform area 1275 mm wide x2000 mmlong • minimum clear opening width of 1050mm, • an ambulance stretcher (minimum size 600mm • wide x 2000 mm long) in its horizontalposition. HOSPITALLIFT

  8. LIFT,ESCALATOR AND MOVINGWALKS • Components oflift • Controlroom • Guides • Liftcar • Lift cardoor • Carrail • Counterweight • Controlpanel • Liftpit • Buffer • Hoist way • Hoistrope • Ventilationwindow • Flexiblecable • Drivecrank

  9. LIFT,ESCALATOR AND MOVINGWALKS • LIFT CAR :Platform where passengers or goods istransported. • Passenger elevators shouldbe located at the circulation coreof thebuilding. • minimum width and depthof the car shall be 2000mm • and 1291 mm.(for wheelchair) • Height of the entrance to the lift car shall not be less than 2m. • The rails shall be at least 38 mm clear of thewalls • nominal height of 800 mm from the floor.

  10. LIFT,ESCALATOR AND MOVINGWALKS • alarm button and emergency stop switch shall be at a height of 890mm, • highest floor button no higher than 1.37 m from thefloor. • letters or numbers shall be a minimum of15 • mmhigh • control buttons shall be at least 19 mm min dimensions. • standby power within60 secondsafter • failure of normalpower. • in fire emergency, DO NOT USE LIFT. USE EXIT STAIRS.This • sign shall be in letters not less than 12 mmhigh.

  11. LIFT,ESCALATOR AND MOVINGWALKS LIFT SHAFT:Constructed with reinforcedconcrete. • counterweight: • To grip the liftcar • Reduce the powerof generator • Reduce the braketo • stop the carlifts GEARLESSMOTOR GUARD RAIL: hold the lift from crashing down if the ropebreak.

  12. LIFT,ESCALATOR AND MOVINGWALKS • The width of lift machine room shall be equal to be lift (minimum of 2500mm) • The height shall not be less than 2.30 m throughout under the liftingbeam • the trap door shall not be less than 1.0 m x 1.0m • machine room entrance is less than 1.5m SHAFT PIT – the bottom end ofthe • Lift pits having depth more than 1.6m • shall beprovided shaft is calledpit.

  18. LIFT,ESCALATOR AND MOVINGWALKS • WHAT ISESCALATOR? • An escalator is a moving staircase – a conveyor transport device for carrying people between floors of abuilding. • designed on an incline of 27.3, 30,35 degrees. • If the height is more than 6mthan • incline of 27.3 should begiven • The speed of the escalator, shall not be more than 0.63 m/s for 30o angle ofincline • and 0.50 m/s for 35o angle ofincline.

  19. LIFT,ESCALATOR AND MOVINGWALKS TYPES OFESCALATOR: MULTIPARALLEL PARALLEL: These typeof escalator go up and down simultaneously. CRISS-CROSS: They stacks the escalators that go in single direction and reduces structural space requirement.

  20. LIFT,ESCALATOR AND MOVINGWALKS TYPES OFESCALATOR: 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. SPIRAL TYPE ESCALATORS: Theseare used to enhance the architectural beauty and to save thespace.

  21. LIFT,ESCALATOR AND MOVINGWALKS • COMPONENTS OF THEESCALATOR: • LandingPlatforms. • Truss. • Tracks. • Steps. • Handrail. • Escalator Exterior(Balustrade). • Drivesystem. • Auto-LubricationSystem. • Brakingsystem. • Safety devices. • Electrical & ControlSystems.

  22. LIFT,ESCALATOR AND MOVINGWALKS • Handrail- • operating speed is less than 0.35m/s • the handrail width not more than75mm • Each moving handrail height notless • than 300mm. • BALUSTRADE- • The thickness of theglass • shall not be less than 6mm. • Height 680 mm vertically abovethe nose line of thesteps, balustrade DECK BOARD- These are used for preventing clothing from getting caught and other such problems. deckboard

  23. LIFT,ESCALATOR AND MOVINGWALKS • TRUSS– • The truss is a hollow metalstructure • that bridges the lower and upperlandings. • The ends of the truss are attached to the top and bottom landing platforms via steel or concretesupports. • FLOORPLATE- • flush with the finishedfloor steps • in front of the escalator shall be a minimum of 3m. • STEPS- • Trade shall not be less than 400mm • Riser shall not be more than 220mm. • front and back edges of the steps are each connected to twowheels.

  24. LIFT,ESCALATOR AND MOVINGWALKS • Standard transportation speed ranges between 0.5 to0.65m/s • For a speed of 0.5m/s the theoreticalcapacity • is: • 600mm step width -4500 persons perhour • 800mm step width -6750 persons perhour • 1000mm step width -9000persons/hour • escalators having a vertical rise not more than 6m. • Minimum head room shall notbe • less than 2.3m.

  25. LIFT,ESCALATOR AND MOVINGWALKS • Moving Walk-A power driven, horizontal or inclined, continuously movingconveyor • used for carrying passengers, • horizontally • an incline up to a maximum of 15 degree.

  26. LIFT,ESCALATOR AND MOVINGWALKS • operating speed is less than 0.35 m/s or the width is no more than 530mm. • normal handrail height not lessthan 300mm
