Definitions
- the two balancing arms are separated from the double roller blocks, and only one of the two load hooks with its bearing block is inserted into the corresponding bearing connection on the intermediate rocker of one of the two single roller blocks. This reduces the weight of the bottom block to about half and is now only 17 t.
- a maximum weight of 500 tons can be lifted in this way.
- FIG. 2 shows a bottom block variant composed of a part of the components of FIG. 1 for a maximum load capacity that is approximately half as large. For this purpose, only one of the two double roller blocks 4a, b from FIG. 1 is used.
- connection of a load hook 2a with a single roller block 1 a can also take place without the interposition of an intermediate rocker 3a.
