Abstract

A pulley block for tackles has a pulley surrounded by a covering hood having inlet and outlet openings for a load cable, with a covering element inserted into at least one of the openings and retained by a retaining strip reaching behind an edge of the opening. The covering element has an opening for the load cable that is less than the inlet and outlet opening in the covering hood. The covering element is divided into first and second covering parts such that to mount the covering element on the covering hood with the load cable in a reeved state, the first and second covering parts can be inserted into the inlet and outlet opening via the retaining strips of the first and second covering parts, then reach behind the edge of the inlet and outlet opening, and then be joined to form the covering element in a mounted state.
