In almost all modern multi-floor buildings, Passenger Elevator fujihd.net are required to provide universal access.
There are three main types of elevators commonly used: traction with a machine room, machine-room-less traction, and hydraulic. However, there are variations on each type.
Hydraulic elevators are supported by a piston at the bottom of the elevator that pushes the elevator up as an electric motor forces oil or another hydraulic fluid into the piston.
The elevator descends as a valve releases the fluid from the piston.
They are used for low-rise applications of 2-8 stories and travel at a maximum speed of 200 feet per minute.
The machine room for hydraulic elevators is located at the lowest level adjacent to the elevator shaft.
Conventional Hydraulic FUJI Elevator have a sheave that extends below the floor of the elevator pit, which accepts the retracting piston as the elevator descends.
