6 ·Hydraulic elevators are supported by a piston at the bottom of the elevator that pushes the elevator up 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
A hydraulic elevator requires on average twelve per cent less shaft space than a cable driven elevator as it does not need a counterweight In the case of back pack elevators a single load bearing wall is sufficient and also allows door openings in three directions Con sequently the streamlined hydraulic elevators can be
·Hydraulic Elevators use hydraulic fluid Hydraulic elevators work by using hydraulic fluid typically oil to power the lift mechanism The elevator car is connected to a hydraulic cylinder and as the cylinder fills with oil the car rises When the car reaches the desired floor the flow of oil is reversed and the car descends
Most elevators you come across will be in two main categories of elevators traction elevators and hydraulic elevators Traction elevators are the most common type using cables and counterweights to move the elevator car up and down Hydraulic elevators on the other hand use a piston to raise and lower the elevator car

Hydraulic elevators are used in low rise applications because they are more affordable on the front end compared with traction as well as cheaper to service For decades hydraulic elevators primarily consisted of an in ground jack and a power unit located in a nearby machine room This is known as a traditional hydraulic
·To recap traction elevators can be geared or gearless Similarly hydraulic elevators can be holed or holeless In a holed hydraulic elevator hydraulic cylinders are placed inside of a drilled hole and allow for up to 60 of travel Holeless hydraulic elevators on the other hand don t need a drilled hole
·During the hydraulic elevator installation process you ll come to find that there are a few different types of hydraulic elevators holed holeless roped and machine roomless Holed Elevators In a holed hydraulic elevator hydraulic cylinders are placed inside of a drilled hole and they typically allow for up to 60 feet of travel
