The vacuum handling system at PolyOne Th. Bergmann GmbH in Gaggenau consist of a vacuum tube lifter JumboSprint 35 with a universal sack gripper, a vacuum generator "Schmalz Blower SB-M" and a wall-mounted slewing crane with a jib length of 3,500 mm. The sacks, which are made of heavy plastic material, are relatively easy to grip, lift, move and position, since there is little deformation of the sacks. Thanks to the new high-performance blower SB-M, a worker can quickly lift and move the sacks with the aid of the vacuum tube lifter. This results in a considerable improvement in the throughput without demanding excessive effort on the part of the worker. The reliability of the vacuum handling system and the economical and ergonomical benefits of the system were so convincing that PolyOne quickly equipped all of the relevant production and filling  stations with JumboSprint 35 devices. Today, seven such devices are in use.
