J D Neuhaus presents a conceptual study of a stainless steel air hoist. The study combines the advantages of using compressed air as a method of operation with the hoist construction material of stainless steel. The products will therefore be resistant to corrosion and high levels of humidity, and also easy to clean and disinfect. As the out-going air is extracted and the chain is protected by a bellows, they can also be used in clean rooms. And because compressed air is used as a method of operation, the hoist will also be explosion protected (ATEX) so that they can be used in potentially dangerous atmospheres or areas where organically flammable chemicals are handled.
