What is the principle of vacuum lift?
Learn how a vacuum lift works using air pressure differences to move smoothly between floors—without cables, pits, or heavy machinery.

A vacuum lift (also called a pneumatic lift) operates based on air pressure differences. Here’s how it works:

 

  • Air Pressure Control: The lift uses a vacuum pump to reduce air pressure above the cabin.

  • Upward Movement: Higher pressure below pushes the cabin up.

  • Downward Movement: Releasing air pressure above allows gravity to bring the cabin down.

  • No Cables or Pulleys: The lift is cable-free and uses a self-supporting tube.

  • Energy Efficient: Power is only used while moving up, not while descending.

  • Safe & Smooth: Includes safety brakes and pressure control for smooth travel.
