Problems solved by technology

There is also an arm-raising fire truck used for existing fire rescue and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, which is approximately equivalent to a height of 15 floors. Most of the time, fire officers and soldiers can only look at the "fire" and sigh, let alone go upstairs to save people

There is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. If the ground wind reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to rise to work

In this way, once a high-rise building above 50 meters catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, and the fire-fighting facilities of some high-rise buildings are not complete, and the fire hydrant door is used by residents. Various phenomena such as sundries blockage will bring resistance to fire fighting and escaping

In short, in the traditional high-rise escape, elevators are prohibited and dangerous, and there is a danger of being blocked by fire and thick smoke when taking the stairs, an...
