The invention discloses a hoisting method for a loading assembly of a large excavator. The hoisting method for the loading assembly of the large excavator comprises the following steps: hoisting equipment hoists a hoisting beam through an adjustable hoisting chain and a hoisting belt, so that the hoisting beam is kept in a horizontal state; the distance between front and rear hoisting points is determined on the hoisting beam; the adjustable hoisting chain is hung at the front end of the hoisting beam, and the hoisting belt is hung at the rear end; and in the step (3), according to the loading assemblies with different specifications, a hoisting shaft is hung on the adjustable hoisting chain, and a hoisting ring is hung on the hoisting belt. According to the method, the distance between the front and rear hoisting points is adjustable, the hoisting beam is balanced and adjustable, the loading assembly is balanced and adjustable, and the hoisting operation can be carried out by adopting a single crane, so that the hoisting efficiency is improved, and the labor intensity and the equipment use cost are reduced.
本发明公开了一种大型挖掘机上车总成吊装方法,包括如下步骤:起吊设备通过可调吊链和吊带将吊梁吊起,使吊梁保持在水平状态;在吊梁上确定前后吊点之间的距离;在吊梁前端挂设可调吊链,后端挂设吊带;在步骤3)中,根据不同规格的上车总成,在可调吊链上挂设吊轴,在吊带上挂设吊环。本方法使吊装作业具备前后吊点距离可调,吊梁平衡可调,上车总成平衡可调,且采用单行车即可进行吊装作业,提高了吊运效率,降低了劳动强度和设备使用成本。
