What are the classification of fire engines? What are their uses?

With the continuous development and progress of science and technology, high-rise buildings are increasingly common, and with the continuous and rapid development of the petrochemical industry, high-frequency development of new fire extinguishing agents and the development of transportation are becoming more and more advanced. The former single-type (fire engine) developed in the direction of high performance, high power, multi-series, and multi-species. In addition, in application fields, it has also expanded from traditional towns and industrial and mining enterprises to forest regions, villages, and airports. Wait for the place. In view of the complexity of the fire in the fire scene, various types of fire engines are required to cooperate and cooperate with each other to save. Therefore, depending on the function of various fire engines, they usually focus on different fire extinguishing needs, which is often difficult to accurately classify. At present, classification is generally based on the type, functional use, and chassis load capacity of fire trucks. As the situation has gradually changed, its categories and uses have continued to change.

?, According to the classification of chassis carrying capacity

(1) Light fire engines.

Lightweight foam fire truck

That is, the chassis has a load capacity of only 0.5 to 5 tons of fire engines, including light-research fire engines, light dry powder fire engines, light fire engines, light communication command vehicles, and light foam fire engines.

(2) Medium-sized fire engines.

Denmark's Roskilde's climbing platform fire truck

That is, the chassis has a load capacity of 5 to 8 tons. Such as medium-sized equipment fire engines, propaganda fire engines, smoke fire engines, communications command fire engines, ladder fire engines, dry powder fire engines, water tank fire engines, water fire engines, lighting fire engines, and high-emission fire engines. Ascends the fire engine and so on.

(3) Heavy fire engines.

Heavy water tank fire truck

That is , fire - fighting vehicles with a chassis capacity of >8 tons, such as heavy-duty ladder fire trucks, foam - dry powder fire engines, carbon dioxide fire engines, and water tank fire engines.

Second, according to the classification of the structure type

( A) Van type

(1) Van-type transport vehicles. Firefighting personnel carrier: The vehicle is equipped with protective devices and alarm devices, which are mainly used for transporting firefighters.

( 2) Van-dedicated vehicles.

First, the communications command fire engine. Used as the command of the fire field communications and the command of the fire field. There are telephones, radios and other equipment in the car. There are two types: passenger compartment and cargo compartment.

Second, investigate fire engines. The vehicle is equipped with instruments for the investigation and analysis of fire sites, and video recording equipment and fire rescue tools are also provided. In addition, it is also equipped with rescue tool cabinets, survey boxes and surveying cabinets, equipped with surveyors and analytical instruments such as sounds, liquids, and gases. It can also be equipped with radios, tape recorders, walkie-talkies, etc. according to actual needs. Multi-purpose fire engines for fire, justice and public security systems. For criminal crime scenes, fire scenes, etc., can also be used for factories and mines, geological surveys, universities and other units.

Third, publicize fire engines. Built-in power generation, audio, recording, playback, and video equipment are used to promote firefighting knowledge.

Fourth, the shower car. Built-in shower and hot and cold water supply system, mainly for the field staff to provide shower service.

Fifth, rescue fire engines. Built-in oxygen respirator, stretcher and other medical equipment and supplies are mainly used to help rescue casualties at the scene of the fire.

( II) Filling cars

(1) Water tanker fire truck.

Built blisters, fire water cannon, tank and fire pumps, mainly used to extinguish fires _ like substance. For this type of fire engine, its standard configuration is blisters, water guns and large-capacity water tanks. It not only can independently extinguish the fire, but also can directly save water from water sources, or provide water for other fire engines on the fire site. In water-scarce areas, this fire truck can also be used as a water truck or a water truck. Suitable for general fire fighting.

( 2) Bubble fire engine.

There are built-in foam mixing devices, foam liquid tanks, water tanks, and fire pumps that are used to extinguish the fire. This type of fire truck can use its own foam gun or bubble mixture to fight fire independently, especially those oil fires, which are more applicable. This fire truck is an essential fire truck for oil terminals, airports and petrochemical enterprises.

( 3) Water supply fire trucks.

Built-in large-capacity water tanks are mostly used for the water supply of the fire. This type of fire truck is equipped with a large-capacity water storage tank. In addition, it is equipped with a special fire-fighting pump system. It can save water supply to the front of the vehicle, which is particularly suitable for arid regions.

( 4) Chemical rescue fire truck.

Chemical tanks, fire cannons, and fire pumps are built in, which are mostly used as chemical dangerous goods accident rescue.

(c ) lifting and lifting cars

(1) Platform fire truck.

It is equipped with fire extinguishing devices, manned leveling, telescopic / folding booms, etc., which are mostly used for fighting fires in high-rise buildings. The iconic configuration is a rod-shaped hydraulic boom and its manned platform and fire-fighting spray device. Most of the targets are fires in tall facilities, high-rise buildings, etc. In addition, they are used to rescue valuable materials and rescue trapped persons.

( 2) Lift high jet fire engines.

With fire extinguishing devices, telescopic modular booms, etc., firefighters can remotely control the fire extinguishing device located on the top of the arm on the ground to lift and extinguish the fire. Its iconic configuration is a rod-shaped hydraulic boom and an extinguishing spray device at the top. Firefighters can remotely control the fire extinguishing device at the top of the jib on the ground. They can be used for fire suppression in tall facilities and high-rise buildings, but they cannot be rescued by the accused.

(3) ladder fire truck.

There is a fire extinguishing device. Turntables and telescopic ladders. Its iconic configuration is a telescoping ladder that allows people to traverse up and down. Firefighters can extinguish fires and rescue rescued trapped people. This is especially suitable for fighting fires in tall facilities and high-rise buildings.

Third, according to functional uses classification

(1) Fire extinguishing fire truck.

There are fire extinguishing agents that can independently perform fire suppression. There are dry powder fire engines, CO2 fire engines, foam fire engines, and water tank fire engines.

(2) Airport fire trucks.

California Airport Fire Engine

Fire engines designed for airport fire accidents can fire extinguishing agents in the driving state to extinguish the fire. Mainly divided into airport rescue fire engines, airport rescue pilot fire engines and so on.

( 3) Special service fire engines.

In addition to responsible for fire fighting, he is also responsible for a specific firefighting technology operation. There are mainly propaganda fire engines, fire extinguishers, and lighting fire engines that are commanding fire engines.

( 4) Lift high fire trucks.

Raise the equipment and obfuscation devices to extinguish the fire. The main ones are ladder ladder fire trucks and lift high-ejection fire engines.

(5) Backing fire engines.

Fire vehicles that provide fire equipment with real-time fire-fighting equipment and fire extinguishing agents, including showers, fire-fighting vehicles, fire-fighting equipment, and liquid-supply fire-fighting vehicles.

Fourth, according to the pump installation location

(1) Front pump fire truck.

The front of the fire truck is equipped with a water pump. The advantages of this type of installation are: easy maintenance, and it is more suitable for medium and light fire engines.

(2) Central pump fire engines.

Install the pump in the middle of the fire engine. At present, most of the types used by most fire engines have the following advantages: The vehicle layout is reasonable.

( 3) Rear pump fire truck.

Features for the pump maintenance compared to the home, more convenient.
