  • Patent number: 4799724
    Abstract: The invention relates to a gripping device for supporting caps or the like supporting tops superimposed on the free upper end of concrete mouldings, such as concrete socket-pipes, standing upright. In order to be able to remove the supporting caps, even with different spacing between the ends of the pipes, in an automated manner, for example using a numerically controlled transport and lifting device, the gripping device comprises at least one group of gripping arms which are supported on a supporting frame and which can be moved inwards, out of an initial position into a position of engagement with a supporting cap by means of a common drive, the gripping arms being capable of being stopped independently of one another.
