The results was a complete victory for us both. Saving the day for our customers is always satisfying, but forJDN it's not new. Our hoists have been solving weighty problems in more than 90 countries all over the world. In this case the 100 ton pneumatic hoists were used on site to level these 310 ton cranes. Incredible size and capacity ratio, precision engineering and construction, and their dependability on only 85 PSI compressed air operation made the JDN PR0FI the perfect choice for the job. But this hoist, and the rest of the world famous PR0FI series, can operate at the same performance level mounted overhead on trolleys and in low overhead situations. They are unaffected by dampness, moisture, steam or heat, and the pneumatic operation makes them ideal for situations where sparks and electrical problems cannot be tolerated The ultra sensitive, pull cord speed regulation, built into every PR0FI hoist, was key to this precision Navy operation. The ability of the hoists to be left running indefinitely without damage adds to the exceptional versatility ofthePROFIline. The J. D. Neuhaus Corporation offers a full line with capacities from 500 lbs. to 100 tons, pneumatic hoists, plus a wide variety of trolleys and hoists that operate at 60 PSI or hydraulic power.
