The embodiment of this invention is a high capacity vacuum suction cup that is very light in weight and can hold up a very heavy load. The light weight construction includes a radial laminated, flexible Kevlar® fabric suction cup reinforced with a rigid outskirt ring. The hoist ring attachment assembly is optimally sized for grabbing the cup but not breaking the cup fabric under minimum weight constraint. The suction cup utilizes a gum material sealer ring to seal vacuum on unsmooth but nonporous surface. The suction cup has a vacuum hose attachment nozzle that allows hooking up of external vacuum hose. A typical high capacity suction cup of this invention weighs about five pounds and can hold up more than 2,500 pounds of load. |
