Lifting device for the transportation of flasks

摘要

Previously known lifting devices for transportation of flasks having lateral trunnions at each end and containing radioactive material were not employable for different sizes of large flasks without considerable adjustments and structural alterations. This invention avoids the necessity for such changes and alterations with a lifting device which consists of a crane hook attachment structure on top of a torsion body having cross pieces on its opposite ends from which hang lug side arms for detachable engagement with the trunnions of the flask. One cross piece is rigidly fixed on the torsion body, while the other cross piece is suspended for tilting on a horizontal axis on the torsion body. The lug side arms are suspended from laterally swingable end portions of the cross pieces and are secured to the cross pieces swivelingly around vertical pivots.
