The detachable pulleys are suitable for stringing two or three bundled conductor lines. The pulleys are made up of a special galvanized steel frame and three single pulleys. The single pulleys can be used separately. The wheels are made of aluminium alloy mounted on ball bearings; the lateral ones have the groove lined by a neoprene ring; the central one has the groove made up of wear-proof interchangeable nylatron sectors. The pulleys are supplied with fixed connection.

Grounding device or complete conductive sheaves are available upon request.
