<p>The lifting jack has a pivoting hydraulic cylinder (2) with a piston that is moved in both directions, where the piston is connected with an extendable and retractable foot section (18) of the lifting jack. The cylinder is moved relative to a retainer (4) over a path (22) between two end points (25). A locking element is engaged with a blocking element in one end point of the path, such that the slewing capacity of the cylinder is blocked.</p> |
