Abstract

A vacuum hoisting device for transporting loads having an adhesive surface has at least one suction head which is attached to a hoisting mechanism and has at least one annular seal projecting on its suction side, the vacuum space or vacuum spaces enclosed by the annular seal or annular seals being connected via a connecting line to a vacuum source with a vacuum generator, and a valve arrangement being provided in the connecting line, which valve arrangement can be switched over between a suction position and an air-admission position. In order to obtain a simple and reliable valve arrangement, the hoisting mechanism is connected to the suction head (5) via a connection piece (41) which is movably guided by a guide (35) in such a way that it can be lifted and lowered between two end positions, the connection piece (41) and guide (35) forming the valve arrangement in the form of a three-way axial valve which is located in the bottom end position in the suction position and in the top position in the air-admission position, the connection piece (41) and guide (35) being coupled via at least one change-over switch (58, 59, 60, 61, 68, 69) which permits an upward movement of the connection piece (41) from the air-admission position into the suction position only after the connection piece (41) is lowered twice into the bottom end position. <IMAGE>
