Abstract: The unloading of expedition materials at Zhongshan Station in Antarctica is the key work for all Chinese Antarctic expeditions. Materials are generally transported over the ice, however, during China's 40th Antarctic Expedition, unloading of materials could not be carried out by ice transport because the sea ice was too broken up. The large hatch cover lifting method refers to a transport method using helicopters to lift cargo directly from the hatch cover of the Xuelong to Zhongshan Station. This method was applied at a large scale during this expedition, accumulating technical experience and relevant data for subsequent applications.
