Helen Zhe (300201) said during an agency survey on February 28 that the company's wholly-owned subsidiary Grumman's first product was targeted at the firefighting needs of high-rise buildings above 150 meters in large and medium-sized cities, developed tethered drone high-altitude fire extinguishing equipment with leading standards in the domestic industry, and gradually formed a 120-meter, 150-meter, 180-meter, and 200-meter series of products. Currently, certification tests and tests of the prototype are being carried out. The marketing work has been carried out according to the plan, and it is expected that there will be good development this year. Furthermore, the company recently adjusted its organizational structure and established an emergency department. In the future, it will integrate products such as fire emergency response, power emergency, and nuclear emergency rescue, making the emergency industry an important profit growth point in the future.
