Fittings for Manila or wire rope blocks
In selecting blocks the governing consideration should be the load to be handled, rather than diameter or strength of the rope they will carry. In multiple-sheave blocks the load is distributed among several parts of the rope, whereas the hooks or shackles on the blocks have to carry the entire load. It is not practical to make double blocks twice as strong or triple blocks three times as strong as single blocks, since they would be too heavy and needlessly expensive for general use.
