What are the Advantages of Screw-Driven Lifts?

A screw-driven lift is a type of home elevator that operates using a large threaded steel screw and a matching nut or drive system. As the motor turns the screw, the nut (which is attached to the elevator platform) moves up or down along the screw shaft, lifting or lowering the cabin. The screw and nut drive system was originally developed in Sweden for use in public places such as museums, railway stations, schools and shops.

Benefits of Screw Driven Lifts:

There are numerous benefits of the screw and nut solution. First of all it is extremely safe, robust and reliable. Secondly it is very space efficient and the solutions as a whole is very compact thus require little space and limited building work. The SWIFT EcoDrive is also very silent and provides a smooth ride. In comparison to conventional elevators a screw and nut drive system requires little or no maintenance. Some other advantages of screw driven lifts are:

• No need for a pit or machine room — ideal for homes with space limitations.
• Simple mechanical design — fewer parts than traction systems.
• Self-supporting structure — often comes with its own shaft.

Screw-driven lifts are used in many residential elevator models and are known for their reliability and ease of installation. However, premium brands like SWIFT usually use traction drive systems for smoother, quieter, and more energy-efficient operation. The maximum speed of 0,15 m/s to 0.3 m/s (outside Europe) is optimal for buildings with just a few floors. If your house has more than 6 floors, and you still want to install a home lift, we recommend other solutions than screw and nut.
