A hydraulic elevator starts up very suddenly and they make a humming noise when they move. When you hear that ssssssssssssssssh-mmmmmmmmmmmm­mm. The elevator is hydraulic. Hydraulic elevators also level slowly and typically do not serve more than 6 floors. Hydraulic elevator that do serve more than that are called HIGHdraulics. Traction elevator tend to start up gradually and they don't make a loud motor noise, also they level quicker and travel faster.
