[0004] Then, preliminary positioning is carried out. The engine is slowly moved to the vicinity of the docking position of the cabin shell by using hoisting equipment, the docking interface of the engine is preliminarily aligned with the corresponding interface on the cabin shell by means of optical instruments, laser positioning devices or mechanical guiding devices and the like, and it is ensured that the axes of the two are approximately coincident, and the position and posture of the engine need to be accurately controlled in this process.
