Passenger Elevators

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.


Bed Lifts

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.


Freight Elevators

Freight elevators are generally required to display a written notice in the car that the use by passengers is prohibited (though not necessarily illegal), though certain freight elevators allow dual use through the use of an inconspicuous riser.


Hydraulic Lifts

The concept of an elevator is incredibly simple -- it's just a compartment attached to a lifting system. Tie a piece of rope to a box, and you've got a basic elevator.
