Abstract

A vacuum hoisting device for transporting loads having an adhesive surface has at least one suction head which has several projecting annular seals on its suction side with vacuum spaces being formed which are enclosed by these annular seals and are connected to a vacuum generator, the vacuum generator being connected to the outer vacuum space or outer vacuum spaces via valves which are controlled via feelers scanning in each case the size of the adhesive surface of the load. So that sudden breaking-away and in particular unintentional, renewed lifting of the load after it has been set down are avoided under all conditions, a compressed-air device (51, 52, 53) is allocated to at least one of the vacuum spaces (13), and a control device is provided which switches on the compressed-air device (51, 52, 53) for a certain time after the interruption in the connection to the vacuum generator (16) has been detected and after air has been admitted to this vacuum space (13), a blocking valve (22) being provided for interrupting the air admission. <IMAGE>
