1. Elevator business study
Introduction and Analysis and Outlook

2. Elevator TechnologyClassification
Elevators are classified by their hoist mechanisms
TE: Traction elevators (geared and gearless)
HE: Hydraulic elevators (conventional hydraulic and roped)
PE: Pneumatic elevators

Elevator speeds by technology and building height

3. Low rise buildings (up to 8 floors) 4. TE speeds up to 500 ft/min (2.5 m/s) 5. HE speeds up to 200 ft/min (1.0 m/s) 6. Medium rise buildings (up to 10 floors) 7. TE speeds up to 500 ft/min (2.5 m/s) 8. High rise buildings (more than 10 floors) 9. Speeds from 500 ft/min (2.5 m/s) up to 2000ft/min (10 m/s)
