CES Blocks for Helicopter Stringing

These single blocks are suitable for stringing the pilot rope by a helicopter. The pilot rope is automatically positioned in the (central) wheel. Special guides ensure the correct positioning of the rope during stringing operations. The wheels are made of aluminum alloy mounted on ball bearings.  Lateral ones have the groove lined with a neoprene ring. The central one has the groove made from wear-proof interchangeable nylatron sectors. The frame is made of galvanized steel. The blocks are supplied with fixed connection.

Grounding device or complete conductive sheaves are available upon request.
