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.
