[0002] At present, when the SKD (semi-knockdown) of middle-tonnage excavator is shipped, the lower car assembly must be placed obliquely to meet the shipping requirements. When the lower car assembly is lifted and placed obliquely on the shipping tool using a conventional lifting appliance, the threaded holes of the lower car assembly are difficult to be centered with the fixing holes of the shipping tool, and there is a certain safety risk. There are two general solutions: 1. The position of the lower car assembly is adjusted multiple times. After the lower car assembly is placed for the first time, the misalignment of the two holes is observed, the lower car assembly is lifted again, the position is adjusted, and then placed again until the two holes are centered. 2. The diameter of the fixing holes on the shipping tool is increased to improve the fault tolerance of the centering of the two holes.
