<p>The lifting tool has manipulator arms (2, 3) that are rotatably supported at respective pivoting hinges (4, 5) with respective vertical rotation axes (6, 7). The manipulator arms comprise a retaining unit (10) for retaining a load (1). Support drives (8, 9) act on the pivoting hinges for pivoting the manipulator arms. A control device (11) is operatable by a user for controlling the support drives during retaining of the load by the retaining unit. One of the support drives include a moment limitation in the form of a slip clutch i.e. friction gear.</p> |
