Fire Fighting Truck

Also known as fire truck, it is a vehicle specially used for fire fighting or other emergency rescue purposes. Fire trucks can be divided into pump trucks, ladder trucks and other specialized vehicles according to their functions.

Fire trucks in most areas are sprayed with bright red (there are also bright yellow fire trucks in some areas), with sirens and flashing lights on the roof. Fire truck is the general term for all types of fire fighting vehicles equipped with various fire fighting equipment and fire fighting appliances. It is the main tool for the current fire fighting forces to fight fires and the most basic mobile fire fighting equipment.

Fire truck classification

There are many types of fire trucks, divided into the following types: water tank fire truck, foam fire truck, carbon dioxide fire truck, dry powder fire truck, foam-dry powder combined fire truck

Water fire truck

In addition to the fire-fighting water pump and equipment, the water tank fire truck is also equipped with a large-capacity water storage tank, water gun, and water cannon. Water and firefighters can be transported to the fire scene to fight the fire independently. It can also draw water from a water source for direct fire fighting, or supply water to other fire trucks and fire extinguishing spray devices. The water transport vehicle is suitable for fighting general fires and is a standing fire vehicle for the public security fire brigade and the full-time fire brigade of enterprises and institutions.

Precautions for water tank fire truck

1. Sign

Product Signage

The product label should be fixed under the left door in the cab. The product label must have the following content:

a. Product name and model

b. Fire pump flow

c. Water tank capacity

d. Factory number

a. Product certificate (including chassis)

b. Product manual (including chassis)

c. List of tools and accessories

d. Quality warranty card

All doors of vehicles and equipment boxes should be closed and locked or sealed.

The exposed chromium-plated parts should be coated with anti-rust oil, and the exterior lights and warning lights should be wrapped with plastic film. The engine and fire pump should not have excess water, the fuel tank should not have excess oil, and the battery should disconnect the positive and negative connectors.

3. Transport

When using a driving container, you must comply with the regulations in the instruction manual regarding the driving of a new car. When using iron (water) transportation, the relevant regulations of railway (water) transportation shall be implemented.

4. Storage

When the water tanker needs to be stored for a long time, the fuel and water should be drained out, and it should be parked in a fire-proof, rain-proof, moisture-proof, sun-proof and well-ventilated place, and maintained and maintained according to the product manual.

The function of each part of the water tank fire truck

Generally speaking, water supply fire trucks can be divided into four parts according to their functions. The front part of the fire truck is the cab. The driver and the commander sit in the cab; behind the cab are the positions of other firefighters. Behind the first roller shutter of the car body are various tools, including faucets, fire hoses, etc. Behind these tools is a water tank for storing fire water. Near the rear of the fire truck is the water pump room. As the name implies, this is the place where the pumping water pump is placed. Generally, the water pump cabin has roller shutters on three sides. When the rear roller shutter is retracted, you can see the display screen showing the working status of the water pump. In the water pump cabin, there are generally tools necessary for using the water pump.

Special function description of fire truck

The overall streamlined design, novel appearance, the water pump adopts the sandwich power take-off method, to achieve travel, fire extinguishing synchronized action, economical, practical, maneuverable and flexible, it is a new generation of substitute products of the same type of fire truck. This vehicle is suitable for small and medium cities, fire brigade, fire brigade, township fire station and full-time fire brigade of common mining enterprises to extinguish general material fires.

Dry powder fire truck

Dry powder fire trucks are mainly equipped with dry powder fire extinguishing agent tanks and a complete set of dry powder injection devices, fire pumps and fire equipment and other foam-dry powder combined fire trucks. Dry powder is mainly used to extinguish flammable and flammable liquids, combustible gas fires, and fires from electric equipment, and can also extinguish fires. General material fires. For large-scale chemical pipeline fires, the fire fighting effect is particularly significant. It is a standing fire truck for petrochemical companies.

It is mainly equipped with dry powder fire extinguishing agent tanks, dry powder injection devices, fire-fighting water pumps and fire-fighting equipment, etc., mainly using dry powder to extinguish combustible and flammable liquids. Combustible gas fires, live equipment fires, and general material fires can also be extinguished. For large-scale chemical plant pipeline fires, the fire fighting effect is particularly significant. It is a standing fire truck for petrochemical companies.

Maintenance of dry powder fire truck

Dry powder fire trucks need frequent maintenance to keep the truck in normal condition. Drivers are often very concerned about maintenance, because they know that the car will be driven soon without maintenance, but they are heartbroken by the money they paid for maintenance. Under normal circumstances, the engine oil is changed every 10,000 kilometers or once a year. The brake oil is changed every two years, and the gear oil needs to be changed longer. In addition to the relatively fixed maintenance mileage of these three oils, other clutch oils, power steering oil, water tank water, etc. are all supplemented or replaced according to the situation. The purpose of maintenance is inspection, and the purpose of inspection is prevention. In addition to the above-mentioned liquid things, there are some solid things on the car to change, the most common ones are spark plugs and air filters. Generally speaking, platinum spark plugs are replaced once every 100,000 kilometers, while air filters are generally replaced once every 40,000 kilometers. Then there is the timing belt and its idler set. Only the vehicles that use the timing belt need to be replaced, and the engine with the timing chain design probably does not need to be replaced until it is scrapped. The replacement of the timing belt is the most expensive item in normal maintenance, and it must not be saved. In fact, there are so few things that need to be replaced, because the real purpose of maintenance is not to replace these consumables, but to check whether the vehicle is abnormal.

Many people have the wrong idea that maintenance is just changing the oil. But in fact, changing the oil has never been the focus of maintenance, at best it is routine. The biggest purpose of maintenance is to check, check whether the various parts on the car are damaged or need to be adjusted. The actions during these checks will ensure your driving safety. There are many items to be inspected, and most of them are inspections of the engine, the exterior of the car body, and the chassis. Open the hood to check the water tank, engine oil, variable speed oil tank, power steering hydraulic oil, brake oil, wiper water, battery, belt, air filter, etc. Next, check the wiper, wiper washer nozzle, whole car lights, and then Check the brakes and hand brakes, tires, drive shafts, shock absorbers, various oil seal buffer rubber pads, and pay attention to whether there are abnormal oil stains and various abnormal phenomena under the vehicle.

The oil and oil filter are things that must be changed every maintenance. Before changing the oil, draw out the oil dipstick and check whether the oil is consumed and the viscosity is normal or not before draining the oil. In addition to paying attention to whether the amount of water in the water tank is normal, it is also necessary to pay attention to whether the water color is normal. When the water in the water tank is abnormally dirty, all the water in the water tank must be circulated and updated. The gearbox oil is generally checked for the amount and color of the oil, and the power steering oil is also the same. In addition to replacing the brake oil every two years, check the oil volume and color for each maintenance. Don’t add it in a hurry when the height drops a little. It is caused by the brake cylinder being stretched out due to the wear of the discs. Replace with a new one. The oil volume of the film will rise again.

There are two types of batteries for fire trucks, one is the water-free type and the other is the traditional water-filled type. The water-free type usually depends on the check mark, and the traditional water-filled battery requires pure water to be filled to the full water level. Check the battery usually with a battery inspection machine. When the battery voltage drop is too much, it means that the battery is aging and needs to be replaced. The battery life is usually two years. Generally speaking, the air filter core is replaced every 40,000 kilometers, but it will be checked every time it is maintained to avoid damage. Finally, check the exhaust pollution. Usually, if this is passed, it means that the engine is okay.

Chassis inspection is usually the most difficult to do, because there are no jacking machines, brake force detectors and other equipment. The most important thing to check the brakes is the braking force. Generally, a vehicle should be more than 80% of the vehicle’s weight. The second is to check the thickness of the wafer, and replace it immediately if the thickness of the wafer is less than 2mm. The tires should be checked for tire pressure, wear, tire eating and aging. The tire pattern 1.6mm should be replaced immediately. Check the positioning when eating the tire. The tire needs to be replaced even if the tire pattern is deep. Because the tire will lose its elasticity and grip due to exposure to ultraviolet rays, it is generally recommended that the tire be used without More than 4 years. Then there is to check the transmission and suspension system under the vehicle, basically check whether there is any oil seal damage, abnormal oil leakage, etc.

Foam fire truck

Foam fire trucks are mainly equipped with fire-fighting water pumps, water tanks, foam liquid tanks, foam mixing systems, foam guns, cannons and other fire-fighting equipment, which can independently fight fires. It is especially suitable for fighting oil fires such as petroleum and its products. It can also supply water and foam mixture to the fire site. It is a necessary fire fighting vehicle for petrochemical enterprises, oil transportation terminals, airports and urban professional fire brigades.

High-expansion foam fire trucks are equipped with high-expansion foam generating devices and fire-fighting water pump systems. It can quickly spray a large number of high-expansion air bubbles of 400-1000 times of foaming to isolate the surface of the burning material from the air, play a role of suffocation and cooling, and can remove part of the dense smoke. Enclosed construction site fire, the effect is remarkable.

The correct use of foam fire trucks (cannon trucks) in the fire scene is the basis for extinguishing petrochemical fires.

Foam fire trucks (cannon trucks) are necessary equipment for fighting fires in petroleum, chemical, industrial and mining enterprises, and port cargo yards. Because it also has the performance of a water tank fire truck, the correct use of foam fire trucks is a problem worthy of attention for every fire commander. Due to the special performance of foam fire trucks, most of the fire scenes faced by this kind of fire trucks are petrochemical and other dangerous fire scenes. This type of fire has the characteristics of fast burning speed, frequent changes in the fire scene, high probability of explosion and burning, and great threat to fire trucks and combat personnel. Therefore, in order to make the foam fire truck reach a favorable position on the fire scene, it can quickly start a fire fighting. The following points must be noted:
1. Foam fire trucks should use the side and rear to face the fire field, quickly discharge water and increase to appropriate pressure (take Dongfeng fire truck as an example, the pressure is ≥0.686MP when using the PQ8 gun, and the pressure is ≥0.785MP when using the vehicle-mounted gun), then open Press the water cock, then open the bubble tank outlet ball valve, adjust the mixer to the proper position, aim at the center of the flame, and spray the foam liquid.
2. When using foam guns for close combat, the fire truck should be protected as necessary according to the fire situation. Asbestos cloth can be used to cover the car body, and water mist can be used to cover it when necessary.
3. During the entire fire fighting process, the driver must stick to his post, constantly pay attention to the instantaneous margin of the car’s foam liquid, and fill the foam liquid in time. Once the foam liquid is used up and refilled, it will inevitably affect the entire fire fighting operation.

CO2 fire truck

The vehicle is equipped with high-pressure gas storage cylinders of carbon dioxide fire extinguishing agent and a complete set of spraying devices, and some are also equipped with fire-fighting water pumps. It is mainly used to extinguish fires such as valuable equipment, precision instruments, important cultural relics and books and archives, as well as general material fires.

● Foam-dry powder combined fire truck

The equipment and extinguishing agent on the foam-dry powder combined fire truck is a combination of the foam fire truck and the dry powder fire truck. It can spray different extinguishing agents at the same time or use it alone. It is suitable for fighting flammable gases, flammable liquids, organic solvents, electrical equipment, and general material fires.

● Purchase of fire truck

The purchase of fire trucks is mainly divided into two categories: the purchase of guarded fire trucks and the purchase of special purpose fire trucks.

The purchase of guarded fire trucks: mainly refers to fire trucks in fixed operating environments such as warehouses, residential areas, commercial areas, and special equipment storage areas. It should be for various fire-fighting vehicles that are relatively predictable for firefighting operations. The majority of vehicle units can be based on For actual work requirements and fire fighting facilities, choose relatively more used models. For example, foam fire trucks and dry powder fire trucks can be purchased for large-scale finished fuel storage. Schools and communities can buy water tank fire trucks.

While purchasing the types of fire trucks, the vehicle users should review the manufacturing quality of fire trucks from the following points:

1. The production unit and reputation of the power take-off, the pressure power of the fire pump

2. Assembly tightness of heat insulation board

3. The setting of the storage bin in the instrument and equipment box and the implementation of related equipment

4. It is characterized by a large-capacity water storage tank and a fire-fighting water pump system. It is used as a backup vehicle for water supply at the fire site, which is especially suitable for dry areas. It also has the function of a general water tank fire truck.
