Abstract
A device for swiveling a working unit between a rest position and a work position is disclosed. The unit has an arm and a support structure, one end of the arm being arranged in the support structure in such a way that it can swivel. A swivel arm with an actuating drive is positioned with one end arranged in the support structure in such a way that it can swivel. The other end of the swivel arm has an articulated connection with a lift drive, the second end of the lift drive has an articulated connection with the arm. The swiveling axis of the swivel arm is positioned at a set distance from the swiveling axis of the arm so that the lever arm can be raised. This allows the lift drive to transmit its power to the arm in a working position. This eccentric position of the swivel arm also allows the actuating drive of the swivel arm to switch largely without power when the arm is in the working position. The swiveling device is adapted for use for tap hole plugging machines.
