An assembly kit for cable winches, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, where the assembly kit includes various transmission housing parts for the transmission unit in order to enable the assembly of a cable winch in a C shape or in a quasi-coaxial shape. A method for converting a cable winch, comprising a cable drum, a drive motor, a transmission unit, and a supporting frame, between a C-shape arrangement and a quasi-coaxial-shape arrangement, for which purpose the transmission unit, in the case of the use of different housings, in particular specific housing shells that can be assembled in order to form the different housings, is assembled differently for the C shape or coaxial shape while the same parts, in particular identical shafts, are used within the particular housing.

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.

A cable guide of a cable winch, such as a cable hoisting winch, includes a cable drum having at least one cable groove and a cable guide having at least two base segments expanding into a ring. The two base segments are guided in the cable groove by at least one engaging element and are supported against the cable winch by at least one torque support. Elements for guiding and holding down a cable are arranged on the base segments. To create a simplified and optionally modular design of a cable guide, the base segments may be configured such that at least one torque support and at least one add-on element for guiding and holding down a cable can be secured in a desired arrangement on the base segments.
