The pulleys are designed to facilitate the stringing of the pilot
rope by an helicopter. The central wheel guarantees the precise
positioning of the rope, which is backed up by special guides.
Additionally, the wheels of these pulleys are made of aluminium
alloy and are mounted on ball bearings.
The lateral wheels have grooves lined with neoprene rings, whereas
the central wheel's grooves are made of wear-proof interchangeable
nylatron sectors. The frame is made of galvanized steel and the
pulleys are supplied with a fixed connection. Grounding device or
complete conductive sheaves can also be provided upon request.
