在我矿选矿厂主厂房扩建工程中,需要把二、三吨重的薄腹梁和大型屋面板以及机械设备等吊装在二十几米高的地方。在当时缺乏专用的大型吊装设备的情况下,选厂指挥部充分发动群众,组成三结合的攻关组,利用8根拉紧绳竖起两根吊杆,吊杆之间悬吊钢绳索道,再以牵引钢绳起吊。牵引钢绳可以横向移动。吊杆立在轨道上可以纵向移动(附图)。经一年来使用,效果良好,完成了选厂主厂房的施工安装任务。
In the expansion project of the main factory building of our ore dressing plant, it is necessary to hoist two or three tons of thin webs, large roofing panels, and machinery and equipment at a height of more than 20 meters. In the absence of large-scale special hoisting equipment at the time, the plant headquarters to mobilize the masses to form a combination of three research groups, the use of eight tensioning rope erected two booms, hanging rope suspension between the ropeway, Then pull the rope to lift. Traction rope can move laterally. Boom standing on the track can be moved longitudinally (with photos). After a year of use, the effect is good, the completion of the election plant construction and installation tasks.
