The high floors of the city are rising and the floors are getting higher and higher, which brings great challenges to fire rescue. The fire floor equipment on the floor is too high to quickly reach the control of the fire, and can only be allowed to ravage the fire, causing major fire accidents. In response to this problem, we have developed a dual fire-fighting drone that has a large load capacity, strong wind resistance, high throwing precision, and can fire fire extinguishers remotely in a complex fire weather environment. At the same time, it can also spray fire-extinguishing powder at close range. The double fire fighting drone is a special fire fighting drone for high-rise buildings.
It features a folding fuselage design, super-load and anti-shock design, fast access to high-rise fire scenes, high-powered cameras to observe fire, and firearms to launch firefighting drones.
