What is a common application of pneumatic systems to lift materials?

Vacuum suction is a widely used application in pneumatic systems for lifting materials due to its efficiency and versatility. This method relies on creating a difference in air pressure, where the ambient air pressure pushes against the material to be lifted, adhering it to a suction cup or similar apparatus. This application is particularly effective in industries where handling items like sheets of glass, packages, or other flat surfaces is required.

The strength of vacuum suction comes from its ability to manipulate air pressure to create a strong grip on objects without the need for mechanical grips or claws, making it ideal for scenarios where delicate handling is necessary to prevent damage to the material. Pneumatic systems utilizing vacuum suction can adapt to varying shapes and sizes, significantly enhancing productivity in material handling operations.

The other methods mentioned, like using air motors and hydraulic support, while relevant in certain lifting scenarios, are not as direct or efficient for lifting materials through the principle of adhering them as vacuum suction is. Compression cylinders indeed use pneumatic principles, but they are generally more utilized for actuation and movement rather than direct lifting through the vacuum effect.
