Electric wire rope hoists serialization problem

   For now, the domestic electric  lift hoist  and other lifting industry developed rapidly, especially in the past two years, as China's economic strength gradually improved, driven by the rapid development of the lifting industry, but in comparison with developed countries, too single product variety lack of technological innovation, the specification is not complete.
       CD1 wire rope hoist is that people most frequently used one of the products, but the structural design, speed reducer, safety precautions, electrical control and other areas to consider our electric hoist comparison with the developed countries have yet to progress.load chain Wire rope hoist fewer varieties, specifications missing. Eg: CD1 wire rope electric hoist weighs only 0.5 t, 1t, 2t, 3 t, 5t, 10t these six types, lifting height coverage for the 6-30m, lifting speed :1-5t single speed of 8m / min, 10t single speed 7m/min. Although some domestic manufacturers on the basis of the development of the 10t 16t, 20t, 30t expansion of large-tonnage electric hoist series, but still can not form a more complete and reasonable wire rope hoist  products, and foreign range 0.25-80t lifting capacity and a variety of play l combination of height and lifting speed compared to there is a big gap.
