Product Description

250kg-100ton High Quality Explosion-proof Pneumatic Hoist/Air Hoist
Introduction:
Practice has proved that the pneumatic hoist is the best choice in any environment where safety is the first priority. Compared with the electric driven, the compressed air as the driving medium will not produce any spark. The features of this structure make the pneumatic hoist especially suitable for working in dangerous environment. Our QDH series pneumatic hoist products are very solid, durable and reliable, they are suitable for using in various of heavy industries and have excellent performance in the following industries: aircraft manfacturing and assembly, chemical industry, dairy products processing factory, electroplating factory, fireworks workshop, food industry, foundry, furniture factory, glass industry, cement plant, mechanical engineering, automobile industry, oil depot, onshore and offshore operations, paint shop, papermaking industry, power plants, fine processing plants, shipbuilding industry, space technology, steel mills, textile industry.
