A vacuum gripper comprises a rigid base element and a loop-shaped vacuum seal element. The base element has first and second opposite sides. The seal element is attached at least indirectly to the second side and protruding therefrom in a direction away from the first side. The seal element comprises a contact surface that at least partially contacts with an object surface and an encircling surface oriented transversely to the contact surface so as to define a chamber. The seal element is elastically deformable at the contact surface to enable conforming to the object surface when pressed thereagainst. The vacuum gripper comprises an air extraction means mounted to the first side to be in fluid communication with the chamber through the base element, and configured to continuously extract air from the chamber to cause the contact surface to be urged towards and grip the object surface when pressed thereagainst.

A compressible lip for a suction cup has in its engagement area one or more sectional areas, each of which comprises a flow passage capable of forming a flow restriction together with a surface of an object to be engaged by the lip. The flow restriction formed restricts airflow from the sectional area, thus allowing a suction cup provided with such lip to maintain an overall high vacuum level despite of pressure loss in one, or some, of its sectional areas. A suction cup having such compressible lip is also disclosed.

Battery gripper (12), for attracting by suction and handling starter batteries (26) of, in particular, motor vehicles, having a housing (56), in which a vacuum chamber which can be loaded with vacuum is provided and which has suction openings (84, 84) on the suction side thereof (54) which faces the starter battery to be attracted by suction, wherein the suction side is assigned a flexible lining (82) for contact with the starter battery, wherein the housing has a T-shaped cross section which runs parallel to the suction side, wherein the cross section has a bar section (64) and a web section (66) which extends transversely from the bar section, in such a way that the web section extends between the battery poles (68, 70) of the starter battery when the starter battery is attracted by suction to the battery gripper.
