ABSTRACT:
The gripping device has two gripping arms which are directly connected to one another in a pivotable manner about a common axis. A stop member is positioned in front of the pivot axis. Both gripping arms are pivotally connected to a piston rod of a piston-cylinder unit via toggle levers. The piston rod is displaceable relative to the pivot axis so that the gripping arms can be extended in a single displacement movement and pivoted into their gripping position.
