Hydraulic elevators are heavy-duty elevators built for long-term and frequent use. They also have an ultra-smooth ride quality and are generally very quiet. They are among the best elevators due to their durability, higher carrying capacity and the ability to serve a larger number of floors.These elevators are pushed from the bottom by a giant piston, similar to those you see on service station car jacks. Hydraulic elevators are considered the safest option because the cab is never suspended inside the hoistway. Elevators that use a cable-driven system hold the cab suspended in the air when they are above the ground floor. Pneumatic elevators hold the cab at higher floors by using a brake system. Hydraulic elevators are used extensively in buildings up to five or six stories high. Sometimes, but rarely, up to 8 stories high. These elevators, which can operate at speeds up to 61 meters (200 ft) per minute, do not use the large overhead hoisting machinery the way geared and gearless traction systems do. You need at least 20 to 25 square feet of space to install a residential elevator. Minimum space required for residential elevator will include other factors including the space needed for the maintenance room ( if you pick an elevator model that needs a maintenance room).
For most hydraulic elevators, machine rooms can be easily placed above your elevator shaft. Machine rooms can't always sit above the elevator shaft; for larger systems, elevator machine rooms will need to be placed adjacent to the elevator shaft
