[0002] Maintenance refers to the process of regular inspection and maintenance of mechanical equipment, vehicles, etc. to keep them in normal operation. It includes preventive maintenance, fault diagnosis and repair. Maintenance can extend the service life of maintenance equipment, reduce the possibility of failure, and improve the safety and reliability of equipment. Through regular inspection and maintenance, potential failures can be prevented and repair measures can be taken in time to ensure the normal operation of equipment.

[0003] When performing maintenance on aircraft, a variety of maintenance tools are needed, and aircraft parts that need to be replaced frequently are also needed to facilitate the rapid replacement of damaged parts. The existing maintenance tool transport trailers can mostly place the small tools needed for maintenance in a tool box for consignment, which is convenient for maintenance. However, maintenance requires the use of large and heavy maintenance tools such as jacks, wheel chocks and tow bars, so that the large maintenance tools need to be taken out separately again, which greatly reduces the efficiency of maintenance operations and increases the difficulty of maintenance personnel. To this end, we specially propose a maintenance tool transport trailer. Summary of the invention
