One of the important tools often used by firefighting units to deal with various accident rescue work is fire trucks. The overall development of the domestic fire truck industry is rapid, the number of fire trucks is increasing, and the technology is becoming more and more advanced. In actual rescue, firefighting requires shortening rescue time, improving disaster relief efficiency, and enabling trouble-free rescue in disaster areas. It is also necessary to ensure that fire trucks are in a trouble-free state of preparation. But at present in China, there are not many fire truck repair factories, and the after-sales service of fire truck manufacturers cannot keep up with the demand. There is a lack of equipment for repairing and maintaining fire trucks in the society. Once a fire truck breaks down, it will affect the efficiency of disaster relief and endanger the lives and property of the people. In addition, the "Urban Fire Station Construction Standards" (Construction Standard 152-2011) stipulates that cities above the prefecture level (including) and economically developed county-level cities should set up special service fire stations and combat support fire stations, and each combat service The security fire station should be equipped with a fire truck equipped for emergency repair. The existing fixed-point emergency repair and maintenance of fire stations can no longer meet the needs of disasters and national construction standards.
