<p>A container-lifting device includes a cam, and lifting elements. Each lifting elements has a container carrier on a slide element, a deformable fluid-pressure actuation element, and a guideway, separate from the actuation element, for guiding the slide element. The lifting element moves between first and second lifting positions. The control cam interacts with the slide elements to move them into the second lifting position. The actuation element, when pressurized, pretensions the slide element into the first lifting position. The actuation element has a wall that delimits an interior chamber to which the fluid pressure is applied. The actuation element is a ball-type element, a membrane-type element, or a bellows-type element.</p> |
