Abstract
A pulling shaft extension (2) is fastened to a pulling shaft (1). This pulling shaft extension contains a driver (13) that protrudes outward similar to a flange and is in the form of a ball bearing. A carrying ring (6) of a gripping device (4) is arranged above the driver (13). If the pulling shaft (1) is moved upward, it drives the gripping device (4) upward as soon as its driver (13) contacts the holding ring (6). An actuating piston (18) makes it possible to move gripping arms (5) of the gripping device (4) into a clamping position such that the crystal block is held by the gripping arms.
