Multi-lift crane synchronization is based on the characteristics of modern military equipment designed, it is the use of two or more smaller sets of frequency control hoisting crane at the same time more hanging points and to ensure synchronization of the number of crane and lifting safe and reliable. <br>  <br> <br>200-1500t large-tonnage cranes, due to electrical, mechanical and many other reasons for the restrictions, it must be more than hanging electric lift cranes to meet the demand from the weight, so multiple-lift cranes used for lifting large equipment, such as the hydropower industry to use on large generating units (100 tons -1.0 thousand tons) lifting, equipment and maintenance. <br>32t-1500t simultaneous multi-point crane lift the technical performance of products ranks the international advanced level, leading domestic level. The product won the second prize of scientific and technological progress in Henan Province is a national invention patent product, high-tech products. <br>Starting weight: 32t-1500t <br>Span: 10.5m-31.5m <br>Hoisting Speed :0.25-2 .5m/min <br>Trolley running speed :2-20 m / min
