ABSTRACT:
A maneuvering apparatus for lines such as cables or flexible conduits passing over a direction changing means and having thereon at least one rigid outer accessory with a diameter greater than that of the conduit or cable. The maneuvering apparatus is mounted adjacent the direction changing means, has a retainer and support for the accessory mounted on the conduit, and is moveable with respect to the direction changing means, so that the retainer follows a trajectory outside the direction changing means, from a first position in which the cable accessory is picked up by the retainer upstream from the direction changing means, to a second position in which the accessory is located downstream from the direction changing means and freed from the retainer.
