JD Neuhaus introduces standard feature in emergency lowering device

GERMANY's JD Neuhaus' EH range of air operated hoists has included its recent emergency lowering device as a standard feature on their Profi Ti range from 25 to 60 tonnes lift capacity in the event of total air power failure.

They are suitable for working in hazardous areas or potentially explosive environments. They are insensitive to humidity and dust laden atmospheres and can operate at temperatures from -20C to +70C. Instant starting, minimum maintenance and low air consumption are their positive features, coupled with compact low-headroom design.

Other standard features include emergency shut-off valve together with both anti-climb and anti-drop devices. Optional accessories include increased spark protection, overload protection, rack and pinion trolley drive with two speed travel control and filter silencers.

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.

JD Neuhaus is a privately-owned company, founded in 1745, which provides solutions to almost every material handling problem (hoists, winches and cranes) irrespective of the driving medium: from air, manual and hydraulic hoists up to complete crane installations with explosion proofness.
