Problems solved by technology
[0002] The disassembly and installation of the existing aircraft landing gear usually adopts a frame structure, and the landing gear is placed in the center of the frame, which mainly has the following problems: 1. The frame structure is difficult to move in all directions, and the attitude adjustment is inconvenient; 2. The landing gear column and the The landing gear wheel is first disassembled, and then the landing gear column and the landing gear wheel are respectively installed on the aircraft or disassembled from the aircraft; 3. The disassembly and installation of the front landing gear and the rear landing gear of the aircraft require two sets of equipment, which is expensive
For this reason, some enterprises that need to disassemble and install aircraft landing gear even have to do it entirely by manpower, which not only increases labor intensity and reduces labor efficiency, but also greatly increases the risk factor of workers' work.
