lifting and holding of the most diverse workpieces is achieve using vacuum. The lifting process is carried out using a spiral tube, referred to as the lifting tube. A load handling device is attached to the end of this tube, which primarily operates with vacuum but can also have a mechanical function. A suction cup is placed on the workpiece to be moved,the air in the suction cap and lifting tube is evacuated and the lifting tube contracts like an accordion, causing the workpiece to stick to the suction cup and be lifted. The load is lowered again when the vacuum drops. Depending on the application, the vacuum is generated either by a side channel blower, a vacuum pump, or a multi-chamber ejector. An operating unit attached to the bottom of the tube lifter is used for manual control. This means that just one hand can control the suction, lifting, lowering and release of the load.
