Hydraulic Elevators

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 4 stories and travel at a maximum speed of 1 m per minute. The machine room for hydraulic elevators is located at the lowest level adjacent to the elevator shaft.
