<p>Similarly working operating cylinder structures (OCS) (3) for both directions of swivel couple to a swivelling part. An operating fluid system (OFS) feeds each OCS. A control circuit affecting the OFS has sensors (16-18) and a control device (6). In the OFS there is a connector line (19) between operating areas (4,5) working in opposing directions and a blockable connector line between an operating area and a reservoir (11).</p> |
