近年来,我国工程项目建设规模化、装置大型化的趋势日益明显,大型设备数量不断增多,设备吊装的工艺技术也不断改进和提升。近年来,我国工程项目建设规模化、装置大型化的趋势日益明显,大型设备数量不断增多,设备吊装的工艺技术也不断改进和提升。在这种市场规模经济的要求下,一方面类似AP1000三代核电、千万吨级以上炼油、百万吨级以上乙烯、海洋勘探平台以及正在兴起的煤化工等工程,使得建设项目的规模越来越大。
In recent years, the scale of China’s construction projects, large-scale installations increasingly obvious trend, increasing the number of large-scale equipment, lifting equipment, technology also continue to improve and enhance. In recent years, the scale of China’s construction projects, large-scale installations increasingly obvious trend, increasing the number of large-scale equipment, lifting equipment, technology also continue to improve and enhance. On the one hand, the scale of construction projects is more and more demanding on the one hand, such as AP1000 III nuclear power generation, oil refining above 10 million tons, ethylene above one million tons, marine exploration platform and the emerging coal chemical industry on the one hand, The bigger
