A passenger elevator is designed to move people between a building's floors. Passenger elevators capacity is related to the available floor space. Generally passenger elevators in buildings of eight floors or fewer are hydraulic or electric, which can reach speeds up to 1 m/s (200 ft/min) hydraulic and up to 3 m/s (500 ft/min) electric.
The widths of the main deck and upper deck are 6.50 metres (21.3 ft) and 5.80 metres (19.0 ft) respectively. Passenger capacity depends on the seat configuration chosen by the airline. Current operational configurations show passenger capacities ranging from 379 (4-class layout in Singapore Airlines) to 615 (2-class layout in Emirates).
A double-deck elevator or double-deck lift is an elevator where one cab is stacked on top of another. This allows passengers on two consecutive floors to be able to use the elevator simultaneously, significantly increasing the passenger capacity of an elevator shaft.

While possibly annoying to other passengers on the chairlift, it is preferable to strike the safety gate—that is, it should not be avoided—and stop the lift than be an unexpected downhill passenger. Many lifts are limited in their download capacity; others can transport passengers at 100 percent capacity in either direction. [22]

A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 992 lbs.) [2] Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys.
