There are different ergonomic solutions for lifting open boxes with vacuum.
The boxes can be lifted with suction feet placed above the box, as you can see on the video below. Another solution is to lift the boxes from the side with two suction cups, one on either side of the box. This solution is designed for lifting opened boxes in various sizes that needs to be lifted from the sides. The suction cups can easily be adjusted along the tool to lift boxes of different shapes and sizes.
