Gripping equipment for lifting apparatuses and lifting apparatus provided with such gripping equipment

A gripping equipment for lifting apparatuses comprising:

• a rigid supporting framework which is adapted to be fixed and/or attached to the lifting apparatus;
• one or more manually-operated gripping members which are fixed to said rigid supporting framework and are adapted to grasp and hold a specific object to be moved;
• a revolving joint which is interposed between the rigid supporting framework and the lifting apparatus, and allows said rigid supporting framework to rotate with respect to the lifting apparatus about a substantially vertical, first rotation axis;
• and a mechanical adjustment system that allow to adjust the position and/or orientation of said rigid supporting framework with respect to the vertical;
• wherein said mechanical adjustment system comprises an adjustment assembly which is interposed between the revolving joint and the rigid supporting framework, or between two rigid elements of said rigid supporting framework, for allowing manual adjustment of the tilt and/or misalignment of the rigid framework with respect to said first rotation axis;
• said adjustment assembly comprising a first rigid frame fixed to a first rigid element of the rigid supporting framework;
• an oblong swinging rocker-arm which extends transversely to said first rotation axis is pivoted on said first rigid frame so as to be able to freely rotate about a second rotation axis locally substantially orthogonal to said first rotation axis;
• and at least one manually-operated first tilt adjusting mechanism that connects the swinging rocker-arm in a rigid and manually adjustable manner to said first rigid frame, at a predetermined distance from said second rotation axis, and is capable of adjusting the tilt of the swinging rocker-arm with respect to said first rigid frame while preventing any free movement of the swinging rocker-arm with respect to the first rigid frame.
