J D Neuhaus’ standard range of air or hydraulically operated hoists are ATEX rated and insensitive to both humidity and dust while operating within a temperature range of -20 to +70°C. An adapted monorail hoist, EH-20, was put on extended testing at -45°C. To ensure smooth starting at such an extreme temperature, it is fitted with a pre-heating device to raise the temperature of the drives to -25°C before operation. The hoist is also equipped with cryogenic hydraulic oil to ensure efficient operation within a temperature range of -45 to +40°C. Supplied for lift capacities from 20 to 100 t, it features controlled load lowering in case of oil supply failure. The hoists are suitable for applications involving explosive atmospheres, and are fitted with sensitive, infinitely variable speed control of lifting/lowering and travel operations. They feature fully enclosed and highly robust gear motors, with extremely low noise emissions and integrated overload protection.
