The emergency lowering device recently introduced by J D Neuhaus for their EH range of air operated hoists can now also be supplied as a standard feature on their Profi Ti line from 25 to 60 tonnes lift capacity.
Hoists incorporating the emergency lowering device option are equipped with a separate air tank, with two additional buttons also incorporated into the hand controllers. This air reservoir is automatically maintained at the full working air pressure during normal hoist operations. This ensures the availability of a positive emergency braking system when required, and the air tank is also protected by a check valve. Certification by Det Norske Veritas can also be provided on request, to comply with safety requirements involving applications for offshore cranes as well as power driven hoists.
