<p>The ends (13, 14) of the length beams (12) in the lifting device have at least two stop points (15, 15, 16, 16) for coupling to the open load hooks in the lifting device. The ends of the beams can be releasably coupled to the load hooks using socket pins and without the need for additional tools. Each length beam face is provided with a stop (22). An articulated train is formed by lifting beams which are joined together in an articulated manner and guided along an overhead rail via frameworks. Each lifting beam includes a lifting device and each pair of adjacent lifting devices carries a length beam.</p> |
