为了尽快实现建筑施工机械化,解决垂直和水平运输问题。我厂广大职工在毛主席“自力更生,艰苦奋斗”的伟大方针指引下,在批林整风运动的推动下,组成了以老工人为主体的“三结合”小组,大搞技术革新。在1965年试制成功的“江西—Ⅲ号”四能轻型塔式起重机的基础上,经过几次改型制成了目前这种QT_6—1型塔式起重机。 In order to realize mechanization of construction construction as soon as possible, vertical and horizontal transportation problems are solved. Under the guidance of Chairman Mao’s principle of “self-reliance, hard work and struggle” under the guidance of Chairman Mao Zedong’s Great Rectification Movement, the majority of employees in our factory have formed a “three-in-one” group with old workers as the main body and engaged in technological innovation. . On the basis of the trial-produced “Jiangxi-III” four-energy light tower crane in 1965, after several modifications, this type of QT_6-1 tower crane has been made.
