Graupner,Umlenkrolle,804.1

Umlenkrolle Graupner 804.1 Can be used with the glider winches, Order No. 804 and 807, to avoid damage to the winch line. The pulley is supported in such a way that it can swing to right and left as well as up (gravity pulley). During the winch launch process the pulley automatically adjusts its position accurately in line with the model´s direction of flight, so the cable cannot chafe on the edge of the pulley. As soon as the model is launched, the cable tension pulls the pulley upward, so that the line does not rub on the ground.
