Abstract
The invention relates to a combination double bottom hook block in which two pulley blocks () each with a plurality of pulleys are connected to one another by means of a rocker (), 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 () 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 () which is mounted between the two pulley blocks (), the two pulley blocks () also being secured against tilting.
