Lift.escalator & moving walk

  1. 1. LIFT,ESCALATOR AND MOVING WALKS ARC 05005512
  2. 2. 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 LIFT,ESCALATOR AND MOVING WALKS •Open Lift (bubble type) •Closed Lift (typical type) Hydraulic lift Passenger lift Goods lift Strecher liftCapsule lift Glass lift
  3. 3. LIFT,ESCALATOR AND MOVING WALKS •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 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
  4. 4. Goods lift LIFT,ESCALATOR AND MOVING WALKS PASSENGER LIFT:A lift designed for the transport of passengers.
  5. 5. LIFT,ESCALATOR AND MOVING WALKS FIREMAN'S LIFT •For buildings having height of 15m or more described 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.
  6. 6. LIFT,ESCALATOR AND MOVING WALKS 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
  7. 7. LIFT,ESCALATOR AND MOVING WALKS HOSPITAL LIFT •minimum inside platform area 1275 mm wide x 2000 mm long •minimum clear opening width of 1050 mm, •an ambulance stretcher (minimum size 600 mm wide x 2000 mm long) in its horizontal position.
  8. 8. LIFT,ESCALATOR AND MOVING WALKS 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
  9. 9. 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 mm and 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.
  10. 10. 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 after failure of normal power.
  11. 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. 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) •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

  18. 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. 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. 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.
  21. 21. LIFT,ESCALATOR AND MOVING WALKS 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.
  22. 22. LIFT,ESCALATOR AND MOVING WALKS Handrail- •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 glass shall not be less than 6 mm. •Height 680 mm vertically above the nose line of the steps, •Each moving handrail height not less than 300 mm.
  23. 23. LIFT,ESCALATOR AND MOVING WALKS TRUSS – •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.
