[0002] Tractor trailers are widely used in the logistics field of various industries. They are a convenient means of transportation. In air transportation, in order to transport ground equipment to the aircraft, tractor trailers are usually used to move and transport ground equipment.

[0003] Although existing tractor trailers are capable of moving and transporting equipment such as air conditioners, in actual use, the trailers need to be connected to a vehicle for transportation. When moving alone, they can only be pulled by manpower, which is inconvenient and labor-intensive. In addition, their own moving structure is relatively simple, and their ability to pass through narrow spaces or muddy roads is poor, which can easily affect their flexibility when moving.

[0004] Therefore, in order to address the problems that the above-mentioned existing mobile carrying devices are large in size, bulky in use, and difficult to adapt to different terrains and environments, a labor-saving mobile carrying device for aviation ground equipment is developed. By adding a differential distribution structure, a four-wheel drive structure and a bottom protection structure to the ground carrying equipment, the existing mobile carrying equipment can be used in different ground environments, and the high-power motor combined with the four-wheel drive structure can improve the flexibility of the mobile device in moving when carrying other equipment.
