What Is a Vacuum Elevator and How Does It Work?
A vacuum elevator is a type of elevator that uses air pressure to move the cab up and down instead of traditional cables and pulleys. It works by air entering the elevator shaft, creating a vacuum underneath the cab and causing it to rise. Similarly, when air is released from the shaft, atmospheric pressure pushes the cab down. Vacuum elevators are energy-efficient, space-saving, and require minimal construction work for installation.
