With the ever increasing need for speed and the 24-hour operation of today’s shipping, Hepworth’s 80NM gives an outstanding performance. To ensure a good swept window at 60 knots, the wiper arm design needs to ensure a good blade contact, hence the development of the extra heavy-duty model. Supplied as a fixed arc model for 24 Volt dc. The standard motor has two speeds and a self-parking facility. Insulated earth return and EMC filter are standard. Pantograph and pendulum arms up to 1525mm (60 inches) are available and blades up to 1000mm (39 inches).
