Lifts and Escalators (Schindler)

  1. 1. Lifts and Escalators Hrishi Desai
  2. 2. Lift A vertical transport equipment that efficiently moves people between floors (levels, deck) of a building, vessel or other structure. Generally powered by electric motor, which is driven by traction cable and counterweight systems like a hoist or hydraulic pump.
  3. 3. How elevators work? PUSH VS PULL Push = Hydraulic Pull = Traction
  4. 4. Basic Components Car Hoist way Machine or Drive system Control system Safety system
  5. 5. Importance 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 organisation. UBBL : building with more than 6 storey must provide lifts system. Fire requirements : provide fire lift to be used during fire.
  6. 6. 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/ second).
  7. 7. 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.
  8. 8. Geared and Gear-less Traction Hydraulic
  9. 9. 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 altitudes. Store Lift : Used to transport heavy goods Car Lift : Used specifically to lift a car in multi storey car park or showroom.
  10. 10. Manufacturer’s history 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 distributor. 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.
  11. 11. Models Low-rise hydraulic Schindler 330A : The Schindler 330A hydraulic elevator is the lowest-cost solution for low-rise buildings. Its hole less design and broad range of offerings is practical yet efficient. Low-rise MRL Schindler 3300 : Schindler 3300 machine room-less (MRL) elevator, for low to mid-rise buildings, offers distinct design options, integrated green technology and smooth, quiet performance.
  12. 12. Mid-rise MRL elevator Schindler 5500 : Schindler 5500 machine room-less elevator for mid to high-rise buildings takes configurability to a whole new level with unmatched design and performance features. High-rise elevators Schindler 7000 : Schindler 7000 is Schindler's top-of-the-range elevator system for all high-rise markets worldwide. Destination Technology : Our destination control system delivers smart mobility. It offers personalised service and access control, and unmatched performance in new and existing buildings.

  16. 16. Escalator 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 buildings. 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.
  17. 17. Models 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 railroad stations.
