Core Viewpoint - The unloading operation at Zhongshan Station by the "Snow Dragon" and "Snow Dragon 2" has been successfully completed, with approximately 2000 tons of supplies delivered in a challenging Antarctic environment [1][2]. Group 1: Unloading Operations - The unloading operation lasted for two weeks, utilizing sea ice transport and helicopter lifting, successfully completing around 2000 tons of material [1]. - The operation faced challenges due to weather conditions, requiring the team to work overnight to prepare supplies [4]. - A total of 365 helicopter lifts were conducted, transporting 1200 tons of materials, which accounted for over half of the unloading work at Zhongshan Station [11]. Group 2: Heavy Equipment Transport - Heavy equipment, such as a large winch and a grader, weighing over 20 tons, posed significant challenges for unloading due to their weight exceeding the maximum lifting capacity of single cranes [18]. - Specially designed giant "shoes" were used to facilitate the transport of heavy equipment across the ice [14][16]. - The unloading team utilized snow vehicles to drag heavy equipment to the Antarctic continent, ensuring safe transport despite the risks involved [12]. Group 3: Team Dynamics and Transition - The unloading team worked long hours, with some members operating under extreme weather conditions, highlighting their dedication and teamwork [9][11]. - The transition of personnel at Zhongshan Station marked the end of the 41st Antarctic expedition, with returning members expressing excitement about returning home [23][29]. - The 42nd Antarctic expedition team is set to continue their journey to other stations, indicating ongoing research and exploration efforts in the region [29].
