Abstract

The disclosure relates to a method for determining the number of rope reevings of a pulley block with a top block and a bottom block, wherein the rope path of at least one rope line of the pulley block, which is covered during a time window, is detected and compared with at least one rope path of a further rope line covered within the time window and/or with the height difference between top block and bottom block changed within the time window, in order to determine the number of rope reevings of the pulley block.
