目前,各机器制造厂生产机器的重量愈来愈大,中小型机器厂正在生产较重型的机器,重型机器厂则要生产更重型的机器,在生产中出现的一个最突出的问题,就是吊车负荷能力不足。我厂起重能力很大的桥式吊车虽属不少,但由于生产发展的需要,很早就感到吊车负荷能力的不足,因此在最近几年来,自己设计和制造了一种提高吊车负荷能力的装置——吊车抬杠。它的负荷能力有26、52、73、130吨等。经过实际经验证明,使用较为方便而且安全,现在介绍出来,以供其他
At present, the weight of the machineries produced at various machine builders is getting larger and larger. Small and medium-sized machine shops are producing heavier machines. Heavy machine builders have to produce heavier machines. One of the most prominent problems in production is the crane Insufficient load capacity. Although there are a lot of bridge cranes with great lifting capacity in our plant, due to the need of production and development, crane cranes have long been lack of load capacity. Therefore, in recent years, we have designed and manufactured a crane cranes The device - crane lift bar. Its load capacity of 26,52,73,130 tons and so on. After the actual experience that the use of more convenient and safe, now introduced for other
