遵照伟大领袖毛主席关于“独立自主、自力更生”的教导,以党的基本路线为纲,在无产阶级文化大革命和批林批孔运动的推动下,由上海工程机械厂、北京市机械施工公司、上海人民电机厂、常德建筑机械研究所及北京建筑机械厂等单位共同研制成功了40t振动沉拔桩机。 Following the guidance of Chairman Mao on “independence and self-reliance” by the great leader, taking the basic line of the party as the key link and under the impetus of the Great Proletarian Cultural Revolution and the Pilot and Pilot Hole Campaign, Shanghai Construction Machinery Factory, Beijing Machinery Construction Company, Shanghai People’s Electric Plant, Changde Institute of Construction Machinery and Beijing Construction Machinery Factory and other units jointly developed a 40t vibration sinking pile driver.
