Abstract: Vacuum elevator is a new kind of elevator, which can realize the up-going and down-going of the car by controlling the differential pressure between the two sides of the car roof. At present, vacuum elevator has formed an industrial chain represented by PVE in foreign countries. In China, vacuum elevator is still in the developmental stage. The related patents mainly focus on three aspects as drive structure modification, accessory parts innovation and control system optimization. Compared with the traditional one, vacuum elevator does not need the pit, wire rope, traction wheel and other devices, and has obvious advantages such as quick assembly, environment-friend, energy saving, fashionable appearance, safety and reliability. Vacuum elevator has very broad application direction and market prospect.

Key words: vacuum elevator, working principle, development situation, advantage and characteristic
