  • Patent number: 10486949
    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.

    Abstract: A cable puller assembly includes a housing assembly, a motor assembly and an anti-fouling device. The motor assembly is secured to the housing assembly and has an output shaft extending outwardly therefrom. The output shaft is rotated about an axis of rotation by the motor assembly. The anti-fouling device has a capstan and a body. The output shaft is operatively associated with the capstan in order to rotate the capstan about the axis of rotation. The body is positioned around an end portion of the capstan proximate to the housing assembly. The body defines a sloped surface that biases incoming rope that wraps around the sloped surface down onto the capstan.
