<p>The puller has two arms (1) separated by a spreading wedge (2) that is arranged at an end of a feed shaft (3), where the arms are designed as half-shells. The feed shaft has a threaded section (17) that projects through an opening (6) of a pressure piece (4). A tension nut (5) is supported at the pressure piece, and stops are attached to the feed shaft, where the stops work together with an end stop (16) of each arm for limiting a path of the spreading wedge. The stops are formed by stop cams (14) that are projected into a groove (15) of the arms.</p> |
