| Abstract: | Owing to the fact that in the course of laying the Bog track slabs of the Beijing-Tianjin Inter-Munecipal Track Project,it is highly required that the aligning should be accurate,and the leveling should be finely adjusted,we have the determination of the general structural form of the lifting mechanism of the cantilever portal crane,the technique of lifting from 4 points while keeping 3 points balancedadopted for the lifting mechnism,as well as the determination of the structural forms of the lifting cart a... |
