There are many different types of elevators and technologies to choose from; traction elevators, hydraulic elevators, belt-driven elevators, vacuum elevators, or screw-driven elevators.
All elevator types have their pros and cons and there are many more different kinds of lifts than can be mentioned here. However, to take a few examples, conventional hydraulic and traction elevators can travel fast, from 2 feet/s to 40 or 50 feet per second, but they also take up a lot of room, given that they require a deep lift pit, a lot of headroom, and a separate machine room and/or control room. Hydraulic elevators also often need a large hydraulic tank. Vacuum elevators, on the other hand, are space-efficient, but the technology is expensive and their lifting capacity is limited.

Our screw-driven elevators travel at a speed of 0.5 feet/second (0.15 m/s), but take up a lot less room than hydraulic elevators and traction elevators, given that our elevators can be installed without a pit and have a top height of only 88 ³⁷/₆₄” (top height is the height of the lift on the top floor). The machine and control room are fitted inside the elevatorshaft, which also makes the whole construction very compact and space-efficient compared to conventional elevators.
