湖北省均县三六○七工厂的铸造车间,由于厂房条件的限制,不少工部(如炉体折装、造型材料运送及配辗等)因位于吊车的跨度与行程之外,故工人的劳动强度大,生产效率低,且很不安全。为此,根据现场条件采用定点吊装,并自行设计制造了一台最大起重量为一吨,吊臂长为五米,能作圆周运动的旋转式悬臂吊(右图)。吊体结构简单,操作灵活轻 Due to the restriction of factory conditions, many workers (such as furnace body refurbishment, transportation of molding materials and rollers, etc.) are located outside the span of the crane and the journey, so the workers in the foundry workshop of 3607 Factory in Jun County, Hubei Province, The labor intensity, low productivity, and very insecure. To this end, according to the site conditions using fixed-point lifting, and to design and manufacture of a maximum capacity of one ton, jib length of five meters, can make circular motion rotary cantilever crane (right). Lifting structure is simple, flexible operation
