With the increasing concentration of urban buildings, fire-fighting facilities are increasingly valued and well-known by people. The concept of firefighting is very wide. From fire fighting to flood relief, oil tank explosions, and even children being trapped, fire protection can be seen in these scenarios. The figure of officers and men today came to recognize the very important fire-fighting ascents in fire fighting equipment. The fire-fighting ascending car is a disaster-relief vehicle used by firefighters to rescue people trapped in high places by the fire, transfer the property of the affected people and ensure the safety of the affected people. The fire escape vehicle is equipped with a lift device, otherwise the fire escape vehicle loses the necessary conditions for high altitude rescue. The accuracy of the fire-fighting ascends the level, which directly affects whether fire officers and soldiers can successfully rescue the affected people. Helping to find a breakthrough point for disaster relief can save prime time for disaster relief. The fire elevation must be properly maintained and maintained at a certain level on the affected high floor. The fire exalt truck is an indispensable part of the urban fire protection system. The quality of the fire exaltation truck cannot be ignored. The normal length of the fire excavation vehicle on the market is 12 meters and the width is about 3 meters. The height due to type and disaster site is not fixed. The most common is 50 meters. A fire truck can carry a maximum of about 100 kilograms. This number is critical, and the efficiency of carrying and disaster relief is directly proportional. Although the fire-climbing vehicles can quickly eliminate fire during the fire and save the affected people, the narrow alleys cannot satisfy the existence of the fire-climbing vehicles. Therefore, the use of fire-extinguishers is also required. There must be a fire exit or a broad one. It is easy to work on the road. If there is no condition for fire engines to enter, no matter how good the fire-climbing car can not solve the problem for the first time, on the issue of the scene of the fire-climbing car, many communities are now in the early design stage to prepare a green channel for the fire-climbing vehicle to prevent dangerous situations. occur. Fire-fighting ascending vehicles are indispensable fire-fighting equipment. High-quality fire-fighting ascending vehicles can not only reduce the damage caused by disasters, but also quicken the rescue of people affected by the disaster. Moreover, good fire-fighting ascension trucks are also an extra layer of safety for soldiers who perform tasks for us. Safeguard!
