A passenger elevator is designed to move people between a building's floors.
Passenger elevators' capacities are related to the available floor space. Generally passenger elevators are available in capacities from 1,000 to 6,000 pounds (450–2,700 kg) in 500 lb (230 kg) increments.
Generally passenger elevators in buildings with eight floors or less are hydraulic or traction, which can reach speeds up to 200 ft/min (1.0 m/s) hydraulic and up to 500 ft/min traction. In buildings up to ten floors, traction and gearless elevators are likely to have speeds up to 500 ft/min (2.5 m/s), and above ten floors, speeds begin at 500 ft/min (2.5 m/s) up to 2000 ft/min (10 m/s).
Bed elevators are deeper versions of passenger elevators, and can be used to carry beds or stretchers in addition to passengers. In hospitals that have separate bed and passenger elevators, the bed elevator is usually reserved for patients only.
Most bed elevators are available in capacities of 750 and 1000kg. Most bed elevators' speed are slightly slower than passenger elevators' speed, to make the patients feel comfortable when riding in the elevator.
Service elevators are normally used by building staff instead of other people. Sometimes, they maybe used to carry goods instead of passengers. Most service elevators are slower than passenger elevators.
The service elevators' dimensions can be the same or larger than passenger elevators, or deep like bed elevators, although not as large as freight elevators.
The observation elevator puts the cab on the outside of the building. Glass-walled elevator cars allow passengers to view the cityscape or the building’s atrium as they travel. By eliminating the hoistways, the observation elevator also offers owners, architects and builders valuable space-saving advantages.
