ABSTRACT

The invention concerns a vacuum lifter to transport loads with an adhesion
surface, comprising at least one suction head suspended from a hoist, said
suction comprising at least one annular seal projecting from its suction side,
the vacuum chamber(s) enclosed by the annular seal(s) communicating with a
vacuum source, a valve furthermore being provided which can be switched
between a suction position wherein the vacuum source communicates with the
pressure chamber or vacuum chambers and a venting position wherein the
communication with the vacuum source is interrupted and the vacuum chamber(s)
is (are) vented or fed with compressed air. To assure venting or
compressed-air supply immediately upon deposition of the load, the hoist is
connected by a fitting 55 to the suction plate 5, said fitting being guided in
vertically displaceable manner between two end positions, a sensor or a limit
switch 59 being provided to detect the lower end position of the fitting 55
and so cooperating with a control means that following lowering of the fitting
55, the valve 20 shall be switched into the venting position if previously
having been in the suction position.
