Abstract

Device for detecting the end of unwinding of a cable on the drum of a winch, this device comprising a crazy roller elastically applied against the turns of the cable and cooperating with a drum control member, characterized: - because the cylinder of the drum has, in front of at least the last unwinding loop of the cable, a throat whose depth is determined so that a distance of detectable level, between this last loop and the other proximal turns, appears; - and because the effective travel of the roller, during which only the control element can be requested, is just equal to this level distance that allows to know with extreme precision the length of cable that remains wound.
