Work. During the lifting process of steel columns, it is necessary to place skids under the steel columns to effectively protect the steel columns, avoid friction with the ground, and ensure that the lifting points and column foot foundations are at the crane boom during the lifting process. above the arc of gyration; second, the sliding lifting method. When using the sliding lifting method, the lifting equipment needs to be operated at the same time. For example, when lifting steel column materials, two groups of machines need to lift the crane at the same time to complete the hooking operation, promote the sliding of the steel column feet, and then complete the sliding lifting operation. When using this method to hoist steel materials, it is necessary to set up a reasonable taxiway at the construction site to effectively ensure the smooth progress of the taxiing lifting work; third, the delivery lifting method. Usually, when using the delivery lifting method, more than two lifting equipment need to be applied, and the equipment needs to cooperate with each other.
但是对于较大型的工件,起吊部分主要需要考虑大型工件起吊的困难性:是否能够将其抓取;起吊的稳定性:是否在起吊后会不会发生滑落,而大型工件常常存在起吊困难,转运危险系数高等亟待解决的问题。However, for larger workpieces, the lifting part mainly needs to consider the difficulty of lifting large workpieces: whether it can be grasped; the stability of lifting: whether it will slip after being lifted, and large workpieces often have difficulties in lifting and transportation. High risk factors and other issues that need to be solved urgently.
