Abstract: An apparatus for lifting (or, otherwise handling) objects, involving a plurality of movable contact members spatially arranged on a longitudinally extendible control element in which control element is movably connected with one or more transverse link mechanisms. According to the invention, each transverse link mechanism is comprised of an extensible and constrictable element, (e.g., a lazy tong mechanism) which is supported by a carriage in the lifting device, in turn, is provided with mountings for the control elements which carry and adjust suction cups in the longitudinal direction so that the longitudinal adjustment of the control elements (and thereby of the suction cups) is accomplished by means of movement of the carriage relative to the lifting device or another carriage. The adjustment of the suction cups in the transverse direction is accomplished by extension or constriction of the transverse link mechanism to increase or decrease the spacing of the control elements.
