ABSTRACT:
A grasping device for handling equipment has clamping fingers (4) which are movable relative to one another and an actuating device (5) for the clamping fingers which consists of piston-in-cylinder units (9, 17) which are coaxially arranged one behind the other and coupled in force transmitting manner. These piston-in-cylinder units are energized in the same sense by the pressure medium. This space saving construction makes it possible to achieve high clamping forces for a given pressure of the pressure medium while maintaining compact external dimensions of the grasping device.
