我厂广大革命职工在毛主席革命路线的指引下,坚持以阶级斗争为纲,发扬“独立自主、自力更生”的革命精神,在1974年底试制成功一台20吨中级工作制的电葫芦小车双梁桥式超重机,可用在机械加工、维修、装配等车间。它与同吨位同跨度的中级工作制电动双梁桥式起重机相比,总重量减轻40%,既节约了钢材,又减少了加工工时。由于它自重轻,可以充分利用厂房基础的承载能力,因而能提高起重量。
Under the guidance of Chairman Mao’s revolutionary line, our revolutionary workers and workers insist on taking the class struggle as the key link and carrying forward the revolutionary spirit of “independence and self-reliance”. At the end of 1974, we successfully produced a 20-ton intermediate-working electric hoist trolley double girder bridge Overweight machine, can be used in machining, repair, assembly and other workshops. Compared with the same intermediate-working electric double girder overhead traveling crane with the same tonnage, the total weight is reduced by 40%, which not only saves the steel but also reduces the processing man-hour. Because of its light weight, can take full advantage of the plant’s foundation carrying capacity, which can improve the lifting capacity.
