Zig Zag Pneumatic Lift project is developed for the users to lift any weight using air pressure. High pressure air is stored in a tank. A cylinder with piston arrangement is connected with a zig zag pattern.

Two pipes connected with ball valves connects the air tank with the cylinder. When one valve is opened, the air rushes out into the cylinder. Therefore the piston moves in one direction.

The rod connected with the piston pushes the zig zag frame so that the lift moves up. When the other ball valve is opened, the air inside the cylinder is released. Therefore the lift comes down.


• Air tank

• Cylinder with piston

• Ball valves

• Zig zag frames


This setup is very cheap.

This uses no electric or hydraulic power
