Background

Natural disasters such as earthquakes, geology and the like frequently occur, and the disasters often cause road blocking and bridge damage, so that post-disaster rescue work is difficult to rapidly develop. The emergency engineering equipment plays a great role in disaster rescue, but due to the factors of large volume, heavy weight, difficulty in disassembly and the like, the existing large engineering equipment cannot be put into a rescue site in time, and the rescue efficiency is seriously influenced. Moreover, the working conditions of on-site rescue operation are complex, the requirements of rescue functions are diversified, and the existing equipment needs various types of machinery to cooperate with each other during operation, so that the rescue efficiency is low.

At present, some manufacturers of engineering equipment develop hydraulic excavators capable of being rapidly disassembled and assembled for disaster rescue, the weight of a disassembling unit is about 3 tons, and the hydraulic excavators are suitable for air transportation of helicopters, but the requirements of the air transportation of the helicopters on weather and altitude are severe, and the hydraulic excavators are uncertain in use. Large-scale equipment can be delivered by adopting water transportation modes such as a slot crossing gate bridge and the like, but certain condition requirements are required for a water area channel and a wharf, and the method cannot be generally applied; light transportation equipment such as a charge boat and the like is flexible to use, but the bearing capacity is limited, and no suitable equipment can be transported and thrown by the light equipment at present.

In view of the above situation, there is an urgent need to develop emergency rescue engineering equipment suitable for multi-way transportation and multi-functional operation.
