The grip arrangement comprises a piston-cylinder device and a number of material gripping devices (3') that can be opened or closed by movement of the piston-cylinder device between two positions. Pivoting support surfaces (12c) in the grip devices cooperate with a circular groove in the cylinder. A separate grip unit (50) can be releasably fitted to the free end (3a) of the grip device. |
