How does it work?
An electric vacuum pump, or ejector pump, pumps out the air which creates the desired vacuum level.

When a suction foot is placed (airtight) on an object, e.g. a cardboard box, the result is lower pressure. The difference in pressure makes the tube contract vertically and the object is lifted.

Unique safety
Since the suction foot is always dimensioned in accordance with the vacuum lift tube, you don’t risk dropping lifted objects that are too heavy. If the weight is too much, the tube lift will simply not lift it.

This eliminates the risk of personal injury and damaged goods. If the vacuum pump should stop, the depression is retained so that the load can be lowered in a controlled manner.
