For example, 35-110KV voltage transformers have these problems during operation. Therefore, in order to transport fragile products with high center of gravity and heavy weight, a Chinese invention patent application with application number CN200910306702.1 (publication number CN101633365A) entitled "A Workpiece Transfer Vehicle" discloses a special transportation tool, especially a workpiece transfer vehicle, for transporting workpieces or articles in the production process, especially fragile products with high center of gravity and heavy weight.
