TAWI is introducing a newcomer to their series of vacuum lifters and this one has more than one likeness with its namesake, the cobra.
TAWI project supervisor Carlos Enmark tells the story; The vision was to develop a vacuum lifter that would act as if the operator was Merlin, merely having to point his finger to the goods to have it moved to the next position in the distribution line. Not possible, of course, but the basics are quite simple. The VacuCobra uses the vacuum force from an oilfree working, aircooled rotary vane vacuum pump to create a constant upwards striving motion. The operator then uses the same vacuum and a fingertip control to move the VacuCobra down to attach the suction cup to the load. The vacuum force will assure that the suction cup instantly attaches to and holds anything it comes in contact with. To release there are two choices; a finger tip controlled quick-release function for instant action or the more traditional motion of pushing the suction cup down towards the goods and tilting to let air pass under the suction cup. TAWI president Leif Emblad explains further: The fingertip-controls combined with the upwards striving motion of the VacuCobra is a match that offers a very fast lifting aid. Unlimited horizontal rotation of the goods while being lifted is possible using a bottom swivel. This way the goods can be positioned correctly in midair, while being moved, before being placed on a pallet. An angle adapter ensures full freedom of motion when gripping the load. The goods does not have to be lifted from the top. The operator can flip the suction cup upwards to attach to the side of the goods, important in many distribution lines where goods are not always placed in neat lines on top of each other. VacuCobra handles goods weighing up to 35 kg and lifting heights up to 1800 mm. The lifting speed is approximately 1m/s and variable. The vacuum pump works with a motor speed of 1420 rpm and a vacuum of 150 mbar. The VacuCobra has a unique ergonomic design and the two fingertip controls can easily be moved from the left to the right-hand side to fit all operators.
The VacuCobra will be shown at the Glasstec exhibition i Düsseldorf on November 9th until 13th. More than thirty distributors are working in full force preparing the introduction of the VacuCobra to their local markets world wide. TAWI is a swedish manufacturer of lifting equipment such as VacuEasylift, Protema electric lifts and Lyftman overhead crane systems and jib cranes. Leif Emblad concludes: The ability to combine these products to offer the best possible lifting solution for clients world wide has strengthened our position as market leaders on ergonomic lifting equipment for lighter goods.
