Choosing Between Pneumatic and Electrical Vacuum Lifters for Glass Processing

As a glass processing factory, transferring glass sheets between different processing stations efficiently and safely is crucial. Vacuum lifters are commonly used to lift and move glass sheets, and they come in two different drive modes: pneumatic and electric. In this article, we will explore the differences between these two types of vacuum lifters to help you make an informed decision.

Pneumatic Vacuum Lifter

Pneumatic vacuum lifters are suitable for indoor use in factories that have a gas source. They use compressed air to create a vacuum and lift the glass sheets. However, the weight and length of the air cylinder limit the maximum capacity of the pneumatic vacuum lifter to 500 kg and the lifting height of the glass. If you need to lift heavier glass sheets, you can replace the air cylinder with an electric hoist.

Japan SMC is a reliable brand for the lifting air cylinder, vacuum generator, one-way valve, vacuum manometer, and other components of a pneumatic vacuum lifter.

Electrical Vacuum Lifter

Electrical vacuum lifters, on the other hand, are suitable for outdoor use and factories that don’t have a gas source. They use an electric motor or pump to create a vacuum and lift the glass sheets. Compared to pneumatic vacuum lifters, electrical vacuum lifters have a higher capacity of up to 1 ton and can lift glass to a higher height.

However, a common concern with electrical vacuum lifters is what happens if the power suddenly goes out. To address this concern, most electrical vacuum lifters are equipped with a voltmeter and barometer to monitor the vacuum pressure. They also have a 15-minute power-off protection and insufficient pressure alarm to warn users before the power goes out.

When choosing an electrical vacuum lifter, look for brands that offer high-quality vacuum pumps and electrical apparatus elements for the control system. USA Thomas Vacuum Pump and Japan SMC are two reliable brands for these components.

Which Vacuum Lifter Should You Choose?

When deciding between a pneumatic and electrical vacuum lifter, consider your specific needs and requirements. If you work indoors and have a gas source available, a pneumatic vacuum lifter may be sufficient. However, if you work outdoors or need to lift heavier glass sheets, an electrical vacuum lifter is the better option.

Other factors to consider when choosing a vacuum lifter include the size and shape of the glass sheets you need to lift, the frequency of use, and the level of automation you require. For example, some vacuum lifters come with adjustable suction cups that can accommodate different glass shapes and sizes. Others have automated controls for lifting, lowering, and tilting the glass sheets.

In conclusion, vacuum lifters are essential tools for glass processing factories to move glass sheets between different processing stations. Pneumatic vacuum lifters are suitable for indoor use and have a lower capacity, while electrical vacuum lifters are suitable for outdoor use and can lift heavier glass sheets to a higher height. Consider your specific needs and requirements when choosing a vacuum lifter and look for reliable brands for the components.
