It is understood that，The polar crane is a heavy lifting device installed in the upper part of the reactor building.，During the construction phase of a nuclear power plant，The polar crane is used to install heavy equipment in the reactor building.，Uch as a steam generator、Reactor pressure vessel、Voltage regulator、Reactor internals and other equipment，During the operation phase of nuclear power plant，The ring crane is used for various services required for reactor shutdown refueling and equipment maintenance in the reactor building.。

The ring crane girder of Unit 3 lifted this time weighs about 417 tons.，It is the heaviest lifting equipment of Hualong 1.，The total hoisting weight is about 594 tons.。In order to ensure the smooth realization of the hoisting node of the ring crane main beam,，The management team of Hainan Nuclear Power Project still selected the 3200-ton crawler crane of Zoomlion, which has made outstanding achievements in the field of nuclear power hoisting.。

Before，Hoisting of Ring Beam and Ring Rail for Unit 3 of Hainan Changjiang Nuclear Power Plant，Also in ZoomlionZCC3200NPPrecise positioning under stable hoisting of crawler crane，Take the New Year“A good start”。

The main beam of the ring crane was successfully put in place.，Necessary conditions are created for hoisting the dome of Unit 3.，It also provides a prerequisite guarantee for the subsequent installation of main equipment.。Zoomlion will continue to take the initiative、Positive action，Continue to build high-performance benchmarking equipment，To contribute to the high-quality development of China's nuclear power industry。
