摘要： The invention relates to a combination double bottom hook block in which two pulley blocks (2, 3) each with a plurality of pulleys are connected to one another by means of a rocker (1), a load hook being mounted in a pivotable manner on the rocker. If use is made here of two lifting cables, each of these lifting cables is led over a pulley block (2, 3) and, in order to achieve the same loading capability if use is made of just one lifting cable, the latter is led, in addition, over a floating pulley (2) which is mounted between the two pulley blocks (2, 3), the two pulley blocks (2, 3) also being secured against tilting.
摘要翻译：本发明涉及一种组合双底钩块，其中两个具有多个滑轮的滑轮组件（2,3）通过摇臂（1）相互连接，一个负载钩以可枢转的方式安装在摇杆。如果在这里使用两根起重电缆，则每个起重电缆都被引导到滑轮组（2,3）上，为了实现相同的载重能力，如果仅使用一根起重电缆，则后者被引导另外，在安装在两个滑轮组（2,3）之间的浮动滑轮（2）上，两个滑轮组（2,3）也被固定而不倾斜。
