<p>A description is given of a device designed to be suspended from loading hooks or pulley blocks fitted to a bridge crane or the like, which is used for handling cylindrical reels with a horizontal hole axis. It consists of two facing L-shaped jaws (3,3') each having a horizontal support arm slidably inserted inside a seat of matching shape formed in a central body (2). Each of the two arms is operated by a control screw (7,7') which is arranged above and parallel to the two support arms and which consists of a long threaded bar (15,15') rotatably associated with the central body on which a nut screw (19,19') connected to the said support arm moves. A motor-driven thrust block (13) with a vertical axis is arranged above the two threaded bars (15,15'). The two threaded bars (15,15') and the motor-driven thrust block are moved by two drive systems arranged substantially above the motor-driven thrust block and alongside the coupling zone. <IMAGE></p> |
