Abstract: A gripping equipment for lifting apparatuses includes a rigid supporting framework which is adapted to be fixed/attached to the lifting apparatus. The equipment has one or more manually-operated gripping members that are fixed on the rigid supporting framework and are adapted to grasp and hold a specific object to be moved. A revolving joint is interposed between the rigid supporting framework and the lifting apparatus and allows the rigid supporting framework to rotate with respect to the lifting apparatus about a substantially vertical, first rotation axis. At least one adjustment assembly is interposed between the revolving joint and the rigid supporting framework or between two rigid elements of said rigid supporting framework and allows the position/orientation of the rigid supporting framework with respect to the vertical to be manually adjusted.

Abstract: A magnetic gripping device having a magnetic assembly in turn having an outer magnetic core, and an inner magnetic core mounted inside the outer magnetic core so as to rotate, about a given axis of rotation, between a first operating position, in which the inner magnetic core prevents the outer magnetic core from attaching magnetically to the surface of a generic part of ferromagnetic material, and a second operating position, in which the inner magnetic core allows the outer magnetic core to attach magnetically to the surface of the part; the gripping device also having a torque-control actuating device, which, on command, rotates the inner magnetic core in such a manner as to set it selectively to the first or second operating position, while controlling the value of the twisting torque employed in doing so.
