Abstract

The invention concerns a lifting tube as well as a vacuum lifting device with such a lifting tube. The lifting tube has a tube wall extending about a lengthwise axis and enclosing a tube interior, while the lifting tube can be reversibly deformed along its lengthwise axis into an elongated configuration and, with reduction of the tube interior, a contracted configuration. The tube wall has a plurality of outer crease lines, along which the tube wall can buckle to produce the contracted configuration, while the outer crease lines run obliquely to each other so that, when deformed into the contracted configuration, the tube wall experiences a torsion about the lengthwise axis in some sections.
