Nuclear Power Technologies
This is another major hoisting of the three generations of nuclear power technologies after Fuqing Nuclear Power Unit 5. The K2 nuclear island dome is the cap part of the steel lining of the containment vessel. Its external shape is a hemispherical shell with an inside radius of 23.4 meters. The hoisting load is 395 tons. It is one of the largest nuclear power plants with the heaviest and heaviest altitudes in the world. It is a high level of adjustment accuracy of equipment, allowing small errors; Second, the huge size of the equipment, the windward surface of the lifting process is very easy to cause equipment shaking; Third, the crane carrying more than 27 meters with a large span, increasing the lifting difficulty; Lifting height and docking accuracy is high, the allowable error of only 2 mm, the crane operating speed must be precise control. All units participating in the construction of China's nuclear construction will make concerted efforts to fully prepare an...
